• Get the effective distribution of Esxi VCpu

  Hi all

  1 I want to get the effective distribution of VCPU on host. For example: when I run the command esxitop I can see the assignment of vcpu runtime.  I googled on this topic, but find scripts with total vcpu account which includes powered OFF Vm more who use any host VCPU.

  
  

  2. it's just to say this attribution of real VCPU on esxi same counting vcpu of powered on VM host?
  

  I know my question is newbie, but any help will be appreciated. Please provide you powercli for the same thing get the effective distribution of vcpu.

  You can do something like this

  Get-view ViewType - HostSystem-property name, VM |

  Select Name,

  @{N = 'vCPU'; E = {}

  Notice-EEG-Id $_. VM-property Runtime.PowerState, Config.Hardware.NumCpu |

  where {$_.} Runtime.PowerState - eq "receptor"} |

  %{$_. Config.Hardware.NumCPU} |

• Virtual machines by IP range, containing vCPU vRAM, VMDK Info

  I need to create a script PowerCLI, to search for all the virtual machines in a range of specific IP (for example 172.26.x.x) in vCenter, containing the following:

  • data of vCPU
  • data to vRAM
  • Data VMDK

  This information will be used to determine adequate capacity as VMs reside on legacy hosts and so need to be migrated to a new cluster.

  Any help would be much appreciated?

  You should be more specific about what exactly you want with vRAM/vCPU/VMDK 'data '.

  Assuming that you want the basic parameters of the inventory, use something like this:

  Get-VM | Where {$_.Guest.IPAddress -like '172.26.*'} | Select Name, NumCpu, MemoryGB, UsedSpaceGB | Format-Table -AutoSize
  

• VCPU appropriate Configuration

  Hi guys,.

  I'm new to VM configurations is currently considering options for the deployment of the VM.

  On a CPU (8 cores on each) 2 physical server (total of 16 cores, 32 with HT), which vCPU configurations are allowed?

  for example can I create 8 vCPUs with 4 virtual cores on each due to Hyper Threading? Or the fact that I have just 2 physical CPU limit us?

  Also about the add feature Hot CPU, if I create a virtual machine with for example 1 vCPU with 4 virtual cores, can I add additional core 4 vCPUs while the machine is running at a later stage? Also with this function it then would allow me to keep adding untial of vCPU all 32 hearts have been exhausted?

  Thanks a lot for the clarification of these issues.

  Best regards

  On a physical server on the (8 cores on each) 2 CPU (16 cores in total, 32 with HT)...

  Without HT you will have 16 LCPUs and with HT technology, you'll have 32 LCPUs

  When you create the VM, you will be able to add up to (with HT) 32 vCPU with a single VM in all combinations, such as 8 Virtual Sockets and 4 cores per socket or sockets virtual 4 and 8 cores per socket or... etc

  About the CPU hot pluggable, as a guest within the VM is happy, activate this feature and use.

• Mix single vCPU with Mutiple vCPU VMs VMs

  Hello

  Is there any impact to the unique blend vCPU VMs and mutiple vCPU virtual computers on the same host ESXi?

  Kind regards

  No, no matter how mix you VMs vCPUs different counts. Each vCPU/VM is planned individually from each other.

  As long as you approve too vCPUs (busy) on a host computer, you are right, of course, which applies no matter whether or not all the virtual machines have the same amount of vCPUs.

• can I assign vCPU 32 if the physical host is to have 20 hearts that hyperthreading is disabled

  Dear team,

  I just want to confirm I can assign 32vCPUs to a virtual machine, if a physical host is to have total 20cores and hyperthreading is disabled.

  Please let me know assign vcpus VM is depend on the version of ESXi or VM HW version or is it dependent on ESXI licenses

  need your help on the same.

  Hey Linjo,.

  Indeed, it's picky

  I just test it. The drop of webclients vCPU 5.5 only shows the number of logical cores available on the selected host.

• Get the number of vCPU (hearts by shocket) for vCenter VM

  Hello..

  I'm changing vCPU number scale using a script. I succeeded when the number of cores by shocket is 1, but this does not work if the number of cores, it's more than one, so I want to check the number of cores per VM shocket.

  Please help me get number of vCPU (hearts by shocket) for vCenter VM. Answer as soon as possible it's urgent...

  Thank you!!

  Looking for: vm.config.hardware.numCoresPerSocket where vm is an VC:VirtualMachine object.

  Your total number of cores would be (numCoresPerSocket x numCPU)

• Percentage of loans processor multi vCPu VMs threshold

  Hello

  I'm trying to get some understanding on how to calculate VM CPU ready based on this as best practice white paper page 5:

  Key indicators to measure and track

  Ready (RDY %)

  -% of time a vCPU was ready to be programmed on a physical processor but could not because of the contention of processor

  -Threshold recommended: 10% per vCPU

  
  

  Assuming I'm using ESXTop to get the value of %, made this means that if the percentage of % CPU ready for:

  • 1 x vCPU VM should not be greater than 10%
  • 2 x vCPU VM should not be greater than 20%
  • 4 vCPU x VM should not be greater than 40%
  • 8 x vCPU VM should not be greater than 80%

  is my interpretation correct?

  Hello

  I think and I know, calculation of % CPU RDY for all VM CPU not for a core.

• PowerCLI script to display the number of vCPU by VMhost use

  Hi all

  I'm looking to get help here with powerCLI script to list each total number of ESXi vCPU host that is used to determine if there are any ESXi host CPU is more engaged.

  According to suggestion of performance in some blog vExpert, is around 1: 3 of Jepp core ratio: vCPU allocated, then how to display the report with the powerCLI for something like this:

  PRODESXi01
  Total of nuclei available: 32
  Used by the virtual machine: 28

  PRODESXi02
  Total of nuclei available: 32
  Used by the virtual machine: 38

  So according to the result above, the PRODESXi02 is more committed by 6vCPU allocated to the virtual machine.

  Note: The available total carrots is taken from the value of logical processors from the contents tab, when you click on the vSphere console.

  How to get this report using PowerCLI?

  Thank you

  You mean something like this?

  {Foreach ($esx in Get-VMHost)

  $vCPU = get-VM-location $esx | Measure-object-property NumCpu-sum | Select - ExpandProperty sum

  $esx | Select Name,@{N='pCPU'; E={$_. NumCpu}},

  @{N = 'vCPU'; E = {$vCPU}},

  @{N = "Ratio"; E = {[math]: Round ($vCPU / $_.)} (NumCpu, 1)}}

• Correct allocation of resources to VM CPU with hyperthreading VCPU ESXI 5.5

  Hello

  I've read various articles on trying to size of the allocation of CPU for virtual machines and performance of subjects with overcommitting, but still can't seem to find a definitive answer with hyper threading involved for this particular configuration and hoped that someone could clarify for me.

  Example 1 - Exchange Server 2010

  1 x 6 Core Processor (12 logic with hyper threading)

  There are currently 1 socket and 6 hearts are attributed to him on a possible 12.

  There is only 1 virtual machine running on the server. I would benefit from an increase in the nuclei of one of the following:

  1 outlet, 12 hearts

  6 sockets, 1 core

  12 Sockets, 1 core

  any other configuration?

  Example 2 - server has 2 x 6 Core processors with Hyper threading enabled. (12 cores, 24 logic)

  I want to attribute 2 physical cores to VM1, VM2 4 physical hearts and 6 physical cores to VM3

  Who would do the following:

  VM1 - 1 taken, 2 hearts VM2 - 1 socket, 4 cores VM3 - carrots 1 Socket 6

  VM1 - 1 socket, 4 core VM2 - 1 socket, 8 cores VM3 - 12 hearts 1 socket

  VM1 - 2 taken, 1 core VM2 - 2 Sockets, Sockets 4 hearts 2 VM3, 6 cores

  VM1 - 2 taken, 2 hearts VM2 - 2 taken, 8 cores VM3 - 2 taken, 12 hearts

  VM1 - 2 taken, 1 taken VM2 - 4 kernel, 1 core VM3 - 6 sockets, 1 core

  VM1 - 4 taken, 1 core VM2 - 8 Sockets, 1 core VM3 - 12 Sockets, 1 core

  any other configuration?

  No, you can allocate more vCPU you have. what you said it is fine. I usually go for a ratio of 6: 1. for example, with 12 cores, we have up to 72 vCPUS (it's all compared to the workload type and the size of the virtual machine through)

  I said that you never allocate a unique virtual machine more than the physical cores as the guest on the virtual machine OS think there full hearts to play with no hyper threaded no carrots...

  But hyper threading can give use better ability to commit the resources of the processor because it intelligently uses the additional threads when the performance will not be affected. as long as all virtual machines will not work 100%, then you can add more with no real impact. If you have listed these 3 VMs had to use 100% each you'd be using 100% CPU host not 50%. never use logical cores when it comes to calculations of ability only physical cores

  See you soon

• Maximum VCPU

  Hi all

  I have the following Setup

  Intel xeon CPU

  2.3 GHz processor speed

  Socket CPU 2

  Core processor for socket 4

  Hyper Threading enabled

  Logical processor = 2 Sockets physical * 4 cores per socket * 2 (from HT active) = 16 logical processors

  The calculation above, I understand that 1 - VM can have a maximum of 16 vCPU.

  What is the maximum vCPU limit?

  Is there any report of rule of thumb (Ex 01:12 or 1:8)

  16 * 8 = 128 (where VM 128 I can create at least 1vCPU)

  Kind regards

• vCPU and MS SQL 2012

  Hello

  Could someone tell me how can I set the parameters of vCPU.

  I'll install this machine to 3 virtual servers. 1 Win 2012 Server + MS SQL Server 2012 which point in the most important and most difficult. 2 Win 2008 DC (low voltage). 3 Win 2008 FTP (low voltage).

  

  

  I think, I will give 2 servers. and 3. 1vCPU and 1core. And 4-8GB mem by server.

  But how can I configure SQL Server for best performance?

  JM

  Hello

  First, check the current configuration of the you with new software and if the new software has poor performance on the virtual machine, and then add core to this.

  The subject of memory, try to start with the minimum recommendation and then add memory until the performance is not good for you.

  Finally on vCPUs, he is not different between 2/2 or 1/4 because ESXi 4 hearts to your virtual machine, but it's different for the guest operating system because guest OS see the casings and carrots.

  You should consider it for your licence application, for example a license applications is by socket and you must purchase a license for each socket.

  I recommend, add 1 Plug and 4 hearts to your new virtual machine.
