• pass fails with a missing resource pool alert

  Hi, I have a server dell power edge r510, with ESXi 5.0 is installed in it.

  in one of the virtual machines within this server, I installed Vcenter (I think that it is Version 5.1) everything was stable until the vcenter database gets 10 GB and crashed and I couldn't fix it. So I installed a new windows with vcenter 5.5 inside vps. and for this new vcenter reconnected to the server. so, I've reconfigured resource pools and VPS users again in this new vcenter.

  Watch ESXi host now as does not not to the vcenter. but all virtual machines inside the esxi server work without problems.  I can't reconnect to the host in vcenter, and I can't connect directly to the ESXi via vsphere client and root password.

  but I can log on to the esxi via ssh or console.

  from the console, I restarted the management services, but it does not help.

  the SSH, I ran the following commands:

  status /etc/init.d/vpxa #.

  vpxa is running

  status /etc/init.d/hostd #.

  pass is not running.

  When I restart pass, it is said has started, but after a few minutes still pass fails.

  How can I change the list of resources of the VM to ssh when esxcli do not work?

  I am facing this problem recently, almost all the 5 days the server will respond is not in vcenter, restart the entire esxi server can solve the problem but it apears again.

  I think that resource in vcenter pools doesn't sync properly with the configuration of esxi, as when I connect to the server directly with root/vshpere it shows different configuration than what I see in vcenter!

  and I can't upgrade esxi host because there are about 10 VPSes important and stable running on this server which is my main server and I can not have time on this server or migrate virtual machines to a different server/IPs.

  because I'm not sure of the compatibility of the versions of drivers/bios nic with ESXi 5.5 and I fear that if I update the ESXi from 5.0 to 5.5 I face other questions strangers/downtime.

  I had the server up and running again, by editing this file: /etc/vmware/hostd/pools.xml

  then I found the VPS with id of the pool of resources 11 evil, changed for another pool of resources as the other virtual machines.

  and then made a

  restart the /etc/init.d/hostd

  all started working again without restarting the whole esxi server and turn off virtual machines, I have searched for about 1 day to solve this simple thing!

  even once when I made a few changes in the vcenter, and then restarted resource pool settings move it in ssh, it fails under vcenter changed the VM resource for a bad configuration pool.

  so I changed the resource pool manually xml and restarted spend, while vcenter can connect to the esxi host.

  then vcenter, again removed all the resource pools and created new resource pools. and this question of time is set.

  There was some resource pool configuration that was imported from esxi host to vcenter which was no longer available and has not been deleted in syncronizations between esxi and vcenter when changed resource pools. and the list of the missing resources caused problems.

• Issue of booking Resource Pool

  We used vSphere for a long time and this is the first instance where we watched in the use of resource pools to manage cluster resources.  What we try to do is pool funds from several different material groups buy and then distributed in equal shares of resources between these groups, but allow others to expand beyond what their fair share guaranteed if the resources are not being used by other groups.  And if the other groups are starting to need these resources in return, we want vSphere to restore "ready" transparently resources without causing any VM power issues etc.

  I'm pretty sure resource pools set reservations equal to assignment to a specific group is the way to go here.  If I understand correctly, resource pool bookings do not behave as the reserves of the VM, and even though I had to reserve 100% of cluster across pools resources collectively, a resource pool could grow beyond its reservation as long as there was no pretense.  When the contention starts, additional resources to a pool of resources will be taken away, but only to him guaranteed booking.

  Is my understanding of this is all correct?  Am I sure can cause problems, or a better way to accomplish this task?  Thanks in advance.

  It's the way I used to teach on reservations - think a restaurant which has 100 chairs - like the power of virtual machines on they have a number of chairs that they reserved - if the virtual machine needs more chairs he will get more chairs as long that other virtual machines do not use chairs they reserved - not what happens if all the chairs are reserved - the virtual machine will be not able to come into the restaurant (power on) even if there are empty chairs - if expandable restaurants reservations are activated a call is made to the room dining upstairs (the parent pool) to see if there are chairs available - this works in the same way for memory and cpu but memory has the ability to use the by vm vmkernel swap file and continue my analogy if all chairs are so reserved and a virtual machine appears they could sit on the patio, which can make the conversation (hard affect performance).

  When a virtual machine is turned off (leave the restaurant) it will come out of his reserve make room for several virtual machines.

• Good candidates for the resource pools?

  Hi, I do not currently use resource pools, but often the impression that I should watch more in him.  We have our four node 5.1 cluster 16 web servers (among others in the virtual computer) that are exactly the same and serve the same function.  I was wondering if those who would be good candidates to be added to a pool of resources, so they can take resources needed?  I tend to approve statically the RAM and CPU on these "just in case", but maybe it's stupid, if there is a better way.  Thank you.

  Also consider that if you have no compelling reason to prioritize resources for all virtual machines on one of the virtual computer, then you really don't have a reason to use the resource to all pools.  In this case, each virtual computer will be given some memory he needs on demand, DRS will balance the load between the hosts if a host is out of balance, and there will be fairness when ESXi pray return of VMs pages when there is a conflict.

• 'Custom actions' of the CPU in the Resource Pools: should I also set the VMs child on "custom"?

  Hello world

  Imagine a VMware vSphere 4.1 cluster managed, of course, by vCenter Server, with some 4.1 ESXi hosts.

  This cluster has 3 Pools of resources: development, Production, quality

  Now consider that the Resource Pools have been initially implemented in the following way, about the 'actions' for 'CPU resources':

  -Development: Shared low =

  -Quality: Sharing = Medium

  -Production: Sharing high =

  Several virtual machines were placed in the Resource Pools. Some virtual machines are single vCPU, but others are vSMP ones: some have 2 vCPU and some of them have 4 vCPU.

  Now, I read the following articles of the (large) put at disposal by Duncan Epping, VMware, in his blog "Yellow brick", on "Resource Pools" and actions:

  The Resource Pool priority-Pie Paradox - yellow bricks [written by Craig Risinger]
  http://www.yellow-bricks.com/2010/02/22/the-resource-pool-priority-pie-paradox/

  Actions on Resource Pools

  http://www.yellow-bricks.com/2010/12/14/shares-set-on-resource-pools/

  Actions on a Resource Pool, custom scripted

  http://www.yellow-bricks.com/2010/02/24/custom-shares-on-a-resource-pools-scripted/

  Now, imagine that I have manually changed several Pools of resources from low/normal/high "Custom" and gave them the following values:

  -Development: 3000

  -Quality: 6000

  -Production: 9000

  The virtual machines inside each Resource Pool appear to be all set up to 'Actions' = 'Normal '.

  I want to know is this:

  1 - since I changed Resource Pool shares 'Low' / 'Normal' / 'High' to 'Custom', I should / need to change the 'actions' in each individual VM from "Normal" to "Custom"?

  2 - I'm guessing that the sum of the actions of all virtual machines in a Resource Pool must be equal to the actions that I gave to this Pool of resources. Am I wrong?

  3 - I also guess that the only practical way to make this change to Virtual PCs, if necessary, is to generate scripts, preferably using PowerCLI. Friend, I have right?

  Thanks in advance!

  See you soon,.

  Ricardo

  Whatever resources the resource pool level are applicable to this pool of resources and will get the part accordingly. So that resources will be divided between the virtual machines according to the shares they hold.

  Example:-two pool of resources A and B.

  Total cycles CPU = 10000 Cycles CPU

  A part (custom set) = 6000 CPU Cycle.

  Part B (custom set) = Cycle CPU 4000.

  Now a resource pool has three virtual machines powered with shares.so high normal and low on this desire to cycles CPU 6000 cases divided among them in 4:2:1

  VM1 have = 4 * 6000/7 = 3428 cycles cpu.

  VM2 will get = 2 * 6000/7 = 1714 cycles cpu.

  Vm3 will get = 1 * 6000/7 = 857 cycles cpu.

  so according to your requirement, you can change your actions at the level of the virtual machine.

  PS:shares come into picture when there is a conflict.

• DRS rules and Resource Pools

  Is it possible to assign the DRS rules to Resource Pools instead of creating groups of DRS and adding to the DRS group VMs and then creating a rule
  I ask this question because of a problem that I currently have
  I am far from being an expert as you'll see soon and back to the use of support groups
  If it I'll give you my scenario
  I have 4 ESX host in my test group
  2 hosts are connected to zFCP
  And all 4 are connected to independent contractors
  I have a resorce pool call FC and another called ISCSI
  We constantly evolve around VM between these 2 pools
  The highest availability VM remains on the rest on ISCSI FC
  I would like to create a rule that States if a virtual machine is in the RP FC then he must reside on host A and B, and if it resides on ISCSI it can reside on any host
  I realize that there is still other issues involved here as data themselves warehouses
  but it is another matter that he owns the rights
  We migrate VMs and the data store when we leave the virtual machine to another RP 1
  If the rule would be always true
  I would like to hear from you
  on this topic
  for now I just use rules and groups of DRS
  Thank you

  I don't think this is possible from the point of view of rule affinity DRS, as he has no relationship with resources or VM disk pools. This seems to be a single-use resource pools.

  You could probably do with a set of scripts PowerCLI who would check two resource pools and ensure that the virtual machines to the breast have their records on the correct data store and if not do a svMotion.

• Understanding of the resource pools

  I thought I knew pools of resources but realize that my interpretation is wrong and despite reading the documentation and navigation

  messages on this site, I'm still confused and hoping someone can help.

  I thought that:

  1. set up a reserve of 256 MB of Ram on a pool of resources means that each virtual machine has been awarded to a minimum of 256 MB of RAM and that if this

  was not available, then the VM not illuminate.

  2. If the limit has been set to unlimited (or even a limit capped to say 90% of the available RAM) a VM would use more RAM if needed.

  3. the allocation of memory in the definition of a virtual machine in the settings was not relevant because the vm used as much ram has been defined by the resource pool.

  However, I can see my graphics that some virtual machines, while using very little memory, resemble the memory is limited.

  What I mean is that when I look at vcentre: resource - VMS-> guest mem % pool. I see a percentage high and in some cases

  the bar indicator changes from green to yellow. I do not know what threshold is reached - possibly the amount of RAM allocated to the VM in its

  configuration settigs.

  So should I do the following:

  1 build a virtual machine and to allocate as much RAM as I think that the VM needs

  2. set the memory reserve on a pool of resources as being the sum of which has been attributed to each virtual machine

  3 or the reservation to be what I think, that each virtual machine will usually use the value

  4. If done correctly, then vms uses more memory in the limits imposed.

  Is none of this?

  TAM

  1 build a virtual machine and to allocate as much RAM as I think that the VM needs

  Of course, it is better to give more ram and maybe avoid swapping

  2. set the reserve memory on a pool of resources as being the sum of what

  have been allocated to each virtual machine

  Of course, you can, it depends on if you have too many commissioning

  3 or the reservation to be what I think, that each virtual machine will usually use the value

  Resource pools have just two functions restrict or warranty. Constraint is that if you overprovised a virtual computer, you can stop hunger on the other

  VMS. Or guarantee the current host does not have enough resources both by the DRS vmotion virtual machine to another host

  4. If done correctly, then the vms uses more memory limits

  imposed.

• Question about Lab Manager and ESX Resource Pools

  Hello world

  I was wondering if I can get feedback from some of the members of the community.  We used Lab Manager very strongly in our support organizations and it has proved to be a valuable tool.  Recently, we collaborated with the Department of technical training and started hosting online seminars and classes for them using Lab Manager.  Last week we had a fairly large class of users (approx. 45), each duty deploy 2 rather Beefy VMs that were very intensive resources (Jboss, SQL, Mail to name a few).  My colleague and I went through a lot of trials and planning to ensure that our infrastructure can handle the load while allowing our users to date at the same speed and reliability, so that they are used.

  Our Lab Manager ESX server pools made up of the following:

  5 HP DL380 G5 servers with 2 x Quad Core 2.8 GHZ processors (8 cores each) with 32 GB of RAM each

  2 HP DL580 G5 servers with 4 x Quad Core 2.8 GHZ processors (16 cores each) with 128 GB of RAM each

  When the class is running and everyone has made their 2 machines, we noticed for some reason, he was all on ESX2 and 3 deployment (380 s).  Then came the ESX alarms, use of 90% of memory, then more than 100% bringing the disk page.  The CPU usage was at a all time high.

  I look at the 2 580 s and there are about 4 virtual machines deployed on them.

  So my question is...

  How does he know where to launch a Virtual Lab Manager machine?  There's no sense 2 servers have been brought to the red zone, and almost overloaded when the 2 most powerful servers in my farm are nearly dormant.  I noticed sometimes in the past, but not this bad.  Normally, we have about 45-50 computers deployed at some point and it seems to spread them out properly.

  This group of training has access to the same LUN and ESX server with Betclick as any other organization that we have.

  We have decided hosting several sessions of training may be greater than this one and would like to know that the virtual machines will be distributed properly.

  I would like to know your opinion on this

  First to answer your question, then make guess what happens.

  As indicated in response Ilya, LM distributed VMs differently with active DRS resource pools and pools of resources without active DRS.

  LM place VMs when the DRS is not used.

  When DRS is used, we use the DRS admission control to select the host to place virtual machines.

  DRS is turned off, LM uses its own placement routine:

  For each virtual machine, LM filter all managed servers that cannot run the virtual machine. A complete list of patterns are:

  • The managed server has not enough memory or quota for virtual machine to run the virtual machine.

  • The host is not connected to the data store that is the virtual machine.

  • The virtual machine has active state (suspended) and the CPU of the server managed by the waking state has been captured is not compatible with the managed server currently considered.

  • The virtual machine has been a guest on 64-bit and the managed server is not 64-bit capable.

  • The virtual machine has more processors than the managed server.

  • The managed server is not accessible or is set to "prohibit deployments." Not reachable may mean that the lm-agent or its not to ping queries is not answer (this is visible in the list of managed server page).

  Once we have the complete list of eligible servers, we place the virtual machines on the host including the smallest (MemoryReservation % + CPUReservation %). By default, we reserve not CPU on LM VMs, this internship will be largely due to the memory on the host computers if you have not changed the settings of reservation of CPU on your virtual machines.

  For closed deploy to the PF3, force us all virtual machines to go on the same host, so if any virtual machines have any special data store / CPU type specification, all virtual machines is forced to go on this host. If there are conflicting requirements between different virtual machines in the same configuration, deployment will fail. Closed VMs also have another condition to check that is rarely achieved in practice: number of closed networks available on the managed server. By default, this is 20 and you will need more than 20 different configurations closed running on a managed server before you who will strike.  (LM4 allows Cross fencing host, so this does not apply in LM4).

  To make a guess blind because of your distribution problem - if you use the saved state and fencing, it's probably the type of processor.  Processor type can be checked on the host properties page.

  If you not are not I would check that the images can deploy on the 580 s by disabling the 380s and trying to deploy them.

  If you use DRS (which you're not), it could be due to deployment of virtual machines too fast for the algorithm of control for the entrance of VC.  An easy solution for this is to extinguish the DRS on the cluster manager of laboratory.

  We tested load internal repeatedly, the product QA in different laboratories, we run (LM has been used in VMworld Labs for the past couple years and internal systems of training and demonstration for our Organization implemented SE), so no need to worry about this.  I assure you that the first 'real' performance problem you will encounter will be almost certainly due to an overload of your storage array (too many IOPS / s)... and for that you have to distribute content in data warehouses and use techniques of creating paths to balance the load.

  Kind regards

• VM / resource pool Configuration

  Now that I've answered my own question, and the little light in my head is enabled, I have a better understanding of the relationship between the virtual machines and Resource Pools.  But a follow-up question that I hope that experts can answer that for me is this: after I have create a pool of resources and define the limits of the resources, what I have to change anything on the virtual machines?  In other words, if the virtual machines are configured for unlimited CPU and memory, they are limited by the amount of correct pool?  What would be the reasoning to restrict the VMs and the memory, if I can control it by a pool of resources?  At least for me and please correct me if I'm wrong, if I put limits on virtual machines why I would put in resource pools?

  limits/actions/reservations for the virtual machines are now applied to resources being provided by the resource pool - for example - if you have 10 GB limit set for the pool of resources out of 64 GB of the bunch, it's-if you have a limited memory set to unlimited for the virtual machine in this resource pool the maximum amount of memory for the virtual machine will never be able to get 10 GB is However if the resource pool memory limit has the unlimited value of the virtual machine will be able to go to 64 GB

• Resource pools & reservations?

  Hello

  My question pools of resources. I'll cut right to hunt.

  If a resource pool is created and a reserve of memory is set to say that this means-4069 MB each VM on the host is allocated physical memory 4 GB when it starts?

  When its given a reserve of say 4 GB it never will give the host it's memory if it is not needed?

  What happens if a guest is only given 2 GB of memory, but the reserve is set to 4 GB. It will only take 2GB or take all 4 GB host?

  Here is my scenario:

  An ESX host is given to 8 GB memory.

  4 VMs were created and given 2 GB of memory each.

  A Resource Pool is created and a reserve memory is set to 4 GB of memory.

  This VM average only 2 can be powered on at the same time? Or all 4 machines can be powered on?

  I wonder because someone went and created a bunch of pools of resources like this to my work. I'm new to the technology, but it seems as if they were incorrect installation. My guess is that they were created after the virtual machine has been powered...

  If a resource pool is created and a reserve of memory is set to say that this means-4069 MB each VM on the host is allocated physical memory 4 GB when it starts?

  N ° this means that the POOL reserves 4 GB to apply to these virtual machines.  ALL VM sharing the resource in a POOL.  Up to 4 GB is shared between the virtual machine in this pool.

  When its given a reserve of say 4 GB it never will give the host it's memory if it is not needed?

  NOPE.  Not once it is used, it is reserved.  If you want to share, just use stock instead of reservations for the swimming POOL.  Increase the priority and this POOL will have a higher priority.

  What happens if a guest is only given 2 GB of memory, but the reserve is set to 4 GB. It will only take 2GB or take all 4 GB host?

  YES.  Once reservations are applied, they don't get until they are not necessary.  Once a virtual computer in that pool gets hold of the memory, he won't give it back unless it is turned off.  But since you apply the reserve to a POOL it is immediate, so if your cluster has 32GB of memory, this POOL booked 4GB, leaving 28 GB to share the rest of the cluster, but only this POOL keeps at least 4 GB of memory to ensure that enough memory is given to its members.  This will be guaranteed to members of this POOL of memory.

  This VM average only 2 can be powered on at the same time? Or all 4 machines can be powered on?

  Well what is happening, is that the booking of the pool takes these and its guarnateed to get memory.  Other virtual machines are going to starve (if not left) until this pool is granted to ALL memory.  Once the pool is enough resource, reset of struggle of pools/VM without reservation on the remaining memory.

  Until you are absolutely certain that your VM do NOT get what they need, I would turn off reservations.  They should be used with caution if you don't know what you're doing, you can really tilt performance and cause problems.  So change the settings of the shared pool, back not book memory and monitor the performance of the virtual machine.  If there seems to be some conflict later, you can always reactivate.

• The list of all the Resource Pools that are part of a group of ESXi

  Hello

  I'm trying to get a piece of code work that will list all the resource pools that are present in a cluster of ESXi.

  • I know I can find what list of resources of a virtual machine resides in.  I don't want that.

  // Find a matching resource pool on an ESXi hosts
    var esxiCluster = esxiHost.parent;
    var esxiClusterResourcePools = esxiCluster.resourcePool_ResourcePool;
  
  
    System.log("what is the ESXi cluster: " + esxiCluster.name);
    System.log("vimtype: " + esxiCluster.vimType);
    System.log("what pools exists: " + esxiClusterResourcePools);
  

  So I know that the vimType will come back with what I expect (ClusterComputeResource).  The question I have is the object "resourcePool" is reference to the root resource list (in my case, it is 'resources').

  What I want is all DRS resource pools are configured.  I need something like "resourcePool_ResourcePool.children".

  Any help is appreciated.

  Thank you

  Hello

  Check if this code example that works in your case:

  var esxiCluster = esxiHost.parent;
  var esxiClusterResourcePools = esxiCluster.resourcePool_ResourcePool;
  var pools = System.getModule("com.vmware.library.vc.resourcePool").getAllChildResourcePool(esxiClusterResourcePools);
  
  // dump names of child pools
  for each (var pool in pools) {
    System.log(pool.name);

• Resource pool limit Datastore Quota

  Hello

  I need to limit the quota of data store for a specific group, e.g. they can only allocate 1 TB to 10 TB data store for their virtual machines.

  CPU and RAM are possible with resource pools, but how can I accomplish this with data warehouses?

  what you are asking for can be easily achieved in vRealize Automation or vCloud Director.

  But in the vSphere environment, you have to achieve by using roles and permissions, where you create datastore with limited storage space and assign permission to users wished to not to exceed the use of storage space after certain limit. That way they won't see all data warehouses and they will not be able to use all the space.

• Resource pools

  We have 3 guests in a cluster, 2 x 16 hearts @ 2 200 mhz and 1 x 20 hearts @ 2 300 MHz, which gives us a total of 116 400 MHz. The maximum limit that I can refer to a resource pool is 103 000 MHz, where would lose us the other 13 400 MHz?

  It is the hypervisor above, which is basically the amount reserved for the hypervisor processes run safely.

  It is editable. There is a nice article where Tom Fojta talking.

• Monitor the IOPS / s in a Resource Pool?

  Hello world

  I am quite new to vROM and just get your feet wet for me.  I've been delving into the book "Mastering Operations Manager vRealize" useful and which was helpful, but I'm trying to understand an important piece on:

  We have pools of different resources for different departments within our Organization, and I try to get a good graph for IOPS / s in each resource pool.  I was able to get a list of all virtual machines in a resource pool by creating a dashboard with the widget resource pool game object selector, then use "Diagnose e/s disk of the Virtual Machine list" view to see all the virtual machines within the list of resources and then for the summary allows you to SUM add them all together.  This gives me a number, but does nothing for this over time.  I'd like to be able to see that number over the next few months (even if it means just go ahead of data today onward, not historical).

  Any ideas?  I think I must be missing something, like the Resource Pool looks like it would be a good way to measure the impact of the drive.  Folder of the Virtual Machine might work also, but is not as clean as I would like.

  Hello world

  Right after I got this resolved so I thought I would mention it here in case anyone else is curious.  It has to do with the SuperMetrics.

  The formula I created is as follows:

  SUM (${adapterkind = VMWARE, resourcekind = VirtualMachine, attribute is virtualDisk | commandsAveraged_average, depth = 1})

  It takes the sum of all virtual machines to a level under the resource pool.  I also used average and Max values, because this helps to show trends and you have aberrant VMs eating a ton of IOPS / s.

  I received lots of help from Iwan Rahabok virtual red point.  Specifically, this thread here: http://virtual-red-dot.info/any-vm-abusing-your-iaas-by-doing-excessive-workload/

• Reservation of CPU Resource Pool

  Hello everyone

  I need feedback on pools of resources, and in particular for the CPU share uses.

  I read the "Mastering Vmware vSphere 5.5" and I understand how Vmware works for the share of the CPU.

  I have the a customer who want to buy me a resource pools for this virtual machine management. He will buy vCPU 26 and 64 GB of RAM.

  I know how to set up the RAM, but I did not how to do for the CPU.

  I started by 26 multiples by the clock of the CPU, but the value is higher or lower than 1 ESXi. So I think I made a mistack.

  Can someone help me to understand how do for the CPU resource pool.

  Thanks in advance for your help.

  Best regards

  Hi Matt,

  Personally, I put a limit of 2 GHz by heart. CPU host have 3.0 GHz. On this way a big vm as you can 'kill' the host and other virtual machines on it.

  When you use the same limit, you will need to set the limit at 52000 MHz (26 x 2000 MHz Cores).

  Kind regards
