• 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);
  }
  

• 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.

• '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,.

  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.

• CloneVM_Task fails on the resource pool when cloning tempalte

  I'm trying to use the CloneVM_Task to clone a template, but it keeps failing because no resource pool.  We have a cluster with no pool DRS/HA or resources configuration, we use the cluster for the VCA mode.

  I have a reference to the host server, but I don't know what is needed for the pool of resources, given that we have not one.

  While

  cloning a virtual machine from a template, the resource pool is a required parameter.

  It specifies the resource pool that this virtual machine should be attached.

  Incase you do not have a resourcePool hierarchy, you must specify the root

  resourcePool 'Resources' as a resourcePool. It's the resourcePool

  managed your ComputeResource object. A ComputeResource always has a root

  ResourcePool associated with him.

  Hi Ishaq,

  Please make sure you remove the card "Crypto" off the coast of the Interface by doing a ' no card crypto toVPNs no interface out ' and then add the necessary commands before reconnecting the Crypto map. Usually when we add a new command "toVPNs xx ipsec-isakmp crypto map" without removing the Crypto Card it starts encrypt all traffic passing through the PIX. After you make the required changes, reapply card Cryptography.

  Hope this helps,

  Kind regards

• 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.

• 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.

  Discover the vSphere resources management Guide, you will find everything you always wanted to know about the Pools of resources and any other topic of management resources in general.

• Remove the Resource Pool

  I looked through the documentation for the SDK and connnot find a method to remove a parent resouce pool. For example, one who is just a level below a Cluster object. I forget just the method?

  http://pubs.VMware.com/vSphere-50/topic/com.VMware.wssdk.apiref.doc_50/Vim.ManagedEntity.html#destroy keep in mind this operation destroyed generally all items in the list of resources as well.

• Use of the Resource Pool with vSphere Essentials

  A silly question but I have to ask anyway:

  I have a license of vSphere Essentials with my two hosts ESXi4.  I knew that he was not in vSphere DRS.  What was not so obvious to me, it's that you need DRS activated in order to create a pool of resources to the cluster level vSphere without it.  (The option to create a new cluster is grayed out). http://kb.vmware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1004098

  So my question is:

  Are there benefits to creating a cluster if you do not have DRS?  I now have to double and create pools of resources at the level of the host for two guests, who is an administrative burden.  In addition, one of the main reasons I have used resource pools was to facilitate the access rights based upon roles to specific virtual machines.   These two will now have to be defined for each host.

  We greatly appreciate your comments on this

  Other than the ability to use the VCA mode and setting up the location of the pagefile.  According to me, there isn't much more to a cluster if you use no HA or DRS.  Since you do not have DRS yor cannot create pools of resources that span multiple hosts within a cluster.

  You will need to create individual pools of resources on each host by taking your host from a cluster and have just in the data center.

• Get the resource pool structure

  If I get the virtual machines on each resourcepool in the list above, I'd be unable to distinguish if Tier1 is from the branch of a branch of Department2\Prod or Department1\Dev.

  How can I get that information, that is to say, the 'level 1' resourcepool (ResourcePool-resgroup-296) is in which parent resource group.

  Thank you

  There are 2 things to consider before attack us the script.

  (1) resource pools can be created in 2 different locations, under a Cluster and a standalone host

  (2) in the vSphere environment, there are some hidden files. One of them is the pool of resources of the parent 'resources '.

  You can find this file under each group and each stand-alone host.

  The script uses a function called Get-RpPath, which makes it much easier to recursively down the structure of resource pool

  The script now prints the hidden folder "Resources" as the beginning but this can be replaced by the name of the cluster or standalone host just above.

  The script begins with the collection of all of the 'Resources' folders that are hidden in your vSphere environment and recursively then descends from the quest of sub-resourcepools.

  $indent = 4
  
  function Get-RpPath{
       param($rp, $level)
  
       Write-Host ($rp.Name).PadLeft($level + $rp.Name.Length, "-")
       foreach($child in $rp.ChildConfiguration){
            $nrp = Get-View -Id $child.Entity
            if($nrp.GetType().Name -eq "ResourcePool"){
                 Get-RpPath $nrp ($level + $indent)
            }
       }
  }
  
  $clusters = Get-Cluster
  $hosts = Get-VMHost | where {-not ($_.ParentId -like "Cluster*")}
  
  $RProot = $clusters | % {
       Get-Inventory -NoRecursion -Location $_ | where {$_.gettype().Name -eq "ResourcePoolImpl"}
  }
  $RProot += ($hosts | % {
       Get-Inventory -NoRecursion -Location $_ | where {$_.gettype().Name -eq "ResourcePoolImpl"}
  })
  
  $RProot | Get-View | % {
       Get-RpPath $_ 0
  }
