• 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.

• 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.

• 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

  Matt

  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

• CLI command (or script) to determine if a resource pool has enough resources to a virtual machine

  Is there if a VMS resource pool has enough resources available to start the virtual machine WITHOUT triggering an error of vSphere PowerCLI script - or a series of commands - which can be used to determine?

  For reasons of performance test, we use a pool of resources with maximum rates for RAM and CPU.  Each virtual machine in the pool has a reservation for CPU and RAM.  Test automation will try to start VMs as much as possible in the pool during the test.  The CLI will return an error when you start the virtual machine may exceed the amount of allowed resources.  When this happens, an error on the console vSphere "insufficient resources".  Instead of constantly from the virtual machine, fault and generates error - is there a way to check to see if there is enough space?

  Thank you

  Jason

  Hi Jason,

  You can try if the following PowerCLI function is what you need. The function does not resemble stretch bookings.

  function Get-VmStartPossible {
    param($VM)
  
    $VM = Get-VM $VM
    $ResourcePool = $VM | Get-ResourcePool
  
    $CpuReservationUsed = $ResourcePool.ExtensionData.Runtime.Cpu.ReservationUsed
    $VMCpuReservation = $VM.ExtensionData.ResourceConfig.CpuAllocation.Reservation
    $ResourcePoolCpuLimit = $ResourcePool.ExtensionData.Config.CpuAllocation.Limit
  
    $MemoryReservationUsed = $ResourcePool.ExtensionData.Runtime.Memory.ReservationUsed
    $VMMemoryReservation = $VM.ExtensionData.ResourceConfig.MemoryAllocation.Reservation
    $ResourcePoolMemoryLimit = $ResourcePool.ExtensionData.Config.MemoryAllocation.Limit*1MB
  
    if (($CpuReservationUsed + $VMCpuReservation -gt $ResourcePoolCpuLimit) -or ($MemoryReservationUsed + $VMMemoryReservation -gt $ResourcePoolMemoryLimit))
    {
      $false
    }
    else
    {
      $true
    }

  You can call the function with:

• 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.

• 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

  Jase

  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 -

• 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.

• Issue of Resource Pools

  I'm relatively new to the VMware Infrastructure. I read a lot of documentation available, but I'm having a hard time getting my head around Resource Pools. I was wondering if someone could point me to documentation that includes examples of how and why the Resource Pools are used in a real production environment. In the meantime, if anyone could answer the following questions, I would appreciate it:

  It seems to me that the RPs have been created to distribute resources according to how many resources needs of an organizational unit. For example if a unit is in need of 5 machines running at 2 mhz each with 2 GB of ram, then a suitable unexapandable PR for this unit would include 10 mhz and 10 gigabytes of ram and if any machine would be created which depleted resources, the machine would not be able to start. Is this correct? If so, then how the RP can manage how much mhz CPU using each machine? If all 5 machines were launched at the same time, would not be the limit of 10 mhz be quickly exhausted? The machine would be stopped / stop? Or would the machine just run with > less < mhz?

  RPs affect DRS or HA? How can he? Because the DRS moves a machine so she uses a fixed amount of resources on a machine, ESX, how RPs come into play if they are universal to the cluster?

  Thank you very much

  psynophile,

  Relevant issues. RPs are used "Undernet world", Yes, but I've not seen too real implementations using it. But everything I've seen, they work very well for purposes of limitation and booking. Answer your questions:

  "any machine would be created which depleted resources, the machine would not be able to start": it depends. The limitation will be strong for the RAM (the sixth VM fuel not on), but for CPU the ESX will try to share the 10 GHz (I guess than the typo in the MHz) with all the virtual machines on the RP - always count you can provide each machine with a reserve of CPU, so if the reservation is greater than the limit , then you may not be able to power on the nth VM.

  If so, then how the RP can manage how much mhz CPU using each machine? If all 5 machines were launched at the same time, would not be the limit of 10 mhz be quickly exhausted? : it depends on the use of each virtual computer processor. The performance will be degraded IF the limit of 10 GHz is not sufficient to them.if you 5 database within this RP servers, they will probably present a performance degradation. But will never halt/stop.

  RPs affect DRS or HA? : as the RPs are on a group level, they do not. DRS will change virtual machines one ESX to another depending on the host CPU/RAM usage. HA won't be affected, only that your reservations can reduce the amount of servers for failover, you have set up for it.

• 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 seem unusually slow?

  So I do a VDI poor-team where I have half a dozen hosts XP running on the ESXi server and each client has a direct mapping of RDP to a XP host.  Works well.  Whish I had a broker for connections for connections to Robin, but it works well!

  I created a list of resources for workstations limit to 1000 MHz and 1024 MB of RAM and dropped each XP guest in this pool.  All of a sudden the XP hosts are dirty slow!  They are not machines busy and each uses on average around 250 MHz and 512 MB of RAM.  However, while the machines are in the resource pool, they are just slow pig!  By clicking the menu start takes 10 seconds to come.  If I take the machines our list resources, does not change the use of more than 10%, but they are fast as lightning?

  Any ideas?

  -brian

  I think the resources in a resource pool to limit the use of ALL virtual machines in this pool.  So when you limit your pool to 1000 MHz and 1024 MB of RAM, you say that EACH virtual machine gets a lot, you are saying that all 6 VMs must share 1000 MHz and 1024 MB of RAM.  On average, this is equivalent to 167 MHz by VM and 170 MB of RAM per virtual computer.  I have not tried running XP on nothing less than a P3 processor within a certain time, but you can see how that can be awfully limiting resources.  Also, keep in mind that ESXi will do when you limit the amount of RAM in a resource pool is to force swapping to disk.  Therefore, it is not that the o/s in each virtual machine will limit the use of memory for applications to 170 MB, is that the virtual machine can handle only 170 MB of RAM and the rest of the memory affected virtual machines is be swapped to disk.  Who is going to be terribly slow...

• 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);

• 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/

• 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.
