vCenter Resource Pool Configuration Question

• 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

• 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.

  l # /etc/init.d/hostd restart

  then I started reading the server logs and found this error output of vm-support: hostd.log

  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.

• Configuration issue Resource Pool

  We do currently not pools of resources within our environment. What we seek to do is implement with reserves resource pools memory based on our VM sizes. For example, we will create a pool of resources of 4 GB for virtual machines with 4 GB of memory, a pool of resources for virtual machines with 8 GB of memory, 8 GB etc. We would then define the reserve of memory halfway (the virtual machine) for each pool. Thus, the 4 GB VM will have a reserve of 2GB. Our goal in doing this is to reduce the size of our swap files. We have a few virtual machines spread in our environment that are configured independently. For example, a 12 GB VM with a reserve of 6 GB has a 6 GB swap file. At the global level, it could save us a lot of space to store data.

  A few questions while doing this, however. What will happen for the VMs who have already activated bookings? The resource pool overrides the individual VM settings?

  And no one sees this as having harmful effects on an HA event? We had problems in the past in a different environment with reservations (big 38 GB +), and when we lost a multitude of virtual machines have been unable to turn on because there was no more available resources.

  Resource pool reservations have no effect on the reservation of the virtual machine in the pool - they are independent

  Difficulties with HA is a question - another is by assigning reservations to all VM you can come to the point where an ESXi host won't have enough memory to satisfy the reserve causing the VM does not start.

• 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

• Question of Resource Pool

  Hi all

  Small question about resource pools. If I create a resource pool, the CPU and memory, I reserve will continue to be shared in the entire cluster until the virtual machines in the pool so require? Or once that I reserve of 20%, the main pool by default (the other virtual machines in the cluster) will no longer have this resource?

  Thank you very much

  Dave

  Hello

  This part of the documentation is not, however, in the main section its in the SDK/API section.

  This is straight from the vSphere 5.5 resources management pdf

  

  This stipulates that if you put a reserve on the list of resources, it will be discounted from the full resources of the parent. The resources are then considered reserved.

  The video came from VMworld 2012 which was all about the launch of vSphere 5.1 then I guess that his reference to this version.

• N + 1 configuration with 4 physical blades that are assigned to a single resource pool

In addition, I want to make it worth the custom action that ensures that the resource pool gets all the time shared four physical hosts in contention.

  Here is the command I use to customize this value. All I need to know is how to customize the number of shares to ensure that he is the owner of all the time the equivalents 4 blades in our cluster.

  Please look at the picture to see the stats on the host machine. Thanks in advance for the help.

  As far as I know, the number of shares of CPU of a resourcepool is a relative number you should see with regard to the number of shares of the other resourcepools CPU.

• Question about Resource Pools

  Hi guys,.

  I studied pools of resources in my lab at home in preparation for the review of VCP 4.  I read the pdf pools resources management:

  http://www.VMware.com/PDF/vSphere4/R40/vsp_40_resource_mgmt.PDF

  I'm a bit confused, I hope someone can clear this up for me.  A practical question indicates that a virtual machine will always fail to turn on if reservation of the virtual machine cannot be guaranteed, however in the KB article below he states that admission control can be disabled.

  http://KB.VMware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1007006

  It is, so I think I understand the fact of not being able to guarantee a reservation of the machine does not necessarily prevent machine market because admission control can be disabled.  Is this correct?

  Reservations must be guaranteed as directed by your comment. Which relates to resource pools.

  Admission control is specifically related to HA and ensure that a virtual machine cannot be turned on if it's availability can be ensured according to admission control policy. HA can use reservations VM more memory General fresh in these calculations.

  Disable the admission control would allow you to power on a virtual machine even if the availability of this virtual machine could not be provided by HA, that is a different situation when the virtual machine lives in a pool of resources.

  Just because you use HA does not necessarily mean that you use resource pools or DRS

• vCenter security - limiting the devs to a Resource Pool

  I want to set up a role limiting a team of developers to the resource pool.  I would like that they are able to create virtual machines and modify, download files to data warehouses, and all the devs thing is usually necessary to do, but keep them in a sandbox is limited to a pool of resources.  I don't want them to be able to play with virtual machines in other pools of resources, or have admin access stuff in vCenter data centre.

  Is it possible, or should I create a second data center and use it for developers?

  I'm fairly new to vCentre, so feel free to correct all incorrect concepts in my mind

  Hello

  Yes it is possible. I do it myself.

  The key is to make a record that matches your resource pools that the permissions on the resource pools don't always translate permissions on the virtual machines. Since you talk about virtual machines and resource pools you need of several buildings.

  The first is to limit what resource pools, they can even see, that by placing a role and permission on the specific resource pool.

  The second is to limit what VMs, they can even see/affect, that placing a role and permissions on the specific folder that mimics the resource pool.

  In addition, you want to apply the network and other permissions, restricting what vswitches what they see when they create a VM, etc..

  Everything is possible but complex quite quickly.

• 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

  B

  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);
  }
  

• Understand how resource pools really work

  In the research on how to properly nail using the resources for the resource pools in our groups, I found that there are nuances that are not specifically documented about 'Booking' vs 'Limit' that relate to Resource Pools. If someone is an expert Resource Pool please chime. I am specifically looking for validation of what we believe is true.

  Here's the deal:

  So based on my interpretation of the response and our conception of resource pools, it looks like the 'limit' is always an important value that decided the full amount of the memory of the virtual computer (reserved memory + swapped memory shared memory + virtual memory) in a pool of resources to all virtual machines and does not imply that memory is drawn from a pool of resources of the parent.

  In our environment, we allow 'extensible booking '. Our question was, 'the value limit of importance. " We assumed that with the 'extensible' NOT VERIFIED that the value reserve limit didn't matter, even if it is not grayed out. So if the limit is not grayed out, it allows resources to be charged to the parent? I understand that this is not the case. In our case, the limit does not mean that the resources drawn from the parent, but seems rather this sets the cap of the memory of all virtual machines in the pool resource can use (reserved memory, expanded memory, shared memory + virtual memory).

  Example (1): we have a pool of resources called "Exchange-RP' 10 GB reserved, not expandable, and a limit of 20 GB. If we have 11 VMs each configured with 2 GB of ram (individual virtual machines have no reservation but the virtual machine is configured to 2 GB).

  We can power on the first 10 virtual machines (10 x 2 = 20 GB) but the 11 will not because it exceeds the limit.

  In this example how the 10VMs become the 2 GB? I guess everyone gets 1 GB of physical memory and consists of 1 GB of virtual memory (swap, shared, etc., not physical ram). At no time is issued physical memory of the mother.

  Example (2): given the exact scenario above. If the unlimited checkbox is enabled (limit is grey = unlimited), it would mean that the VM 11 would now be allowed to be turned on and booking of physical memory it is just must be shared by all the virtual machines in the pool. It seems that once that we receive too many virtual machines powered that there is too little physical ram per virtual computer and we will begin to see the excessive ballooning and swapping then in turn affect performance.

  Please confirm the above examples is accurate of how memory is managed.

  We are looking to validate that the RP limit value is always important as a strict limit of all memory used by the VMs, not only physical (reserved memory). None of the VMware documents speak to this.

  Thank you

  Welcome to the Forums - example 1: I understand, it's the list resources should act as a host that you oversommit the memory assigned to the list of resources - so you should be able to on this 11th VM - with 11 VM all who are in need of 2 GB and with the limit set at 20 GB - if all VMs using their 2 GB and no page sharing occurring I expect to see ballooning by VM vmkernel swap files - now used if you have 2 GB reservations you would be able to turn on 5 VMs in this example because with 5 virtual machines would use you all 10 GB of memory reserved - value and the vmkernel will not power on a virtual machine if it cannot guarantee its reserve-

  Example 2 - see above - even with alimit together, you will be able to oversommit the memory in the RP - the only thing you will earn if you have the limit set to unlimited is that you be Basel to put multiple virtual machines and impact on all users on the ESx host or cluster -

• The provision of Resource Pool error

  Hello, I use VDM Administrator 2.1.0 build-596 and VirtualCenter 2.5.0 Build 147633.

  I created a resource pool in VDM which worked for a few months.  Now I get "error duringdeployment...". date time stamp...: refused permission to perform this operation. "I tried to get this to work with two different users.  One is an administrator at the level of the VM and models.  The other is an administrator at the data center level.  It looks like a problem of permissions for me, but the two users are administrators at each level.  Can someone please point out what I'm missing.  Any help will be appreciated!

• Root user cannot create VMS within the Resource Pool after you rename the Cluster

  Currently, vCenter manages two clusters. I renamed a single cluster and the root user seems now are not allowed to create a new Virtual Machine in resource pools to the title of the group with the changed name. I tried to change the name of the cluster to its original name... no luck.

  The root user can still create a VM under the individual cluster nodes, but not in a resource pool.

  The cluster that has not been renamed yet can be managed completely with the root user. Resource pools it allow me to create a virtual machine.

  I found this last issue and checked on each cluster node that the ACEDataRoleId is-1 for each section: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1031192

  I am at a loss, any help would be greatly appreciated! Thank you!

  I think it's a bug. When I created a new data center and migrate all nodes in cluster about him, the permissions problem I was experiencing did not follow.

  Thank you for your help.

• How can I restrict a resource pool to a single data store?

  I am setting up an environment to exercise for different groups of users and you want to limit/permissions to users in each resource pool so that they see only the data store where their enclave of virtual machines.  I was able to configure the actions of CPU and RAM correctly, but access to storage is stumping me.  Clarification: I'm not worried about storage i/o, just permissions/quotas on the data store itself.  Did anyone done this before?  Any help would be greatly appreciated.  Thank you.

  Exactly what I need.  Thank you very much.

• 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.
