• Using Windows 7 processor on ESXi 4.1

  Hello

  If I assign a guest Windows 7 6 logical processors in ESXi it shows only 2.  I think it's because Windows 7 does support only 2 Sockets.  This means - it does not use the other 4 processors?  If so is there anyway I can set it to several carrots as a single logical processors?

  Thanks for the help.

  David

  This message indicates that you are looking for because I think.  It shows how to move the VM to carrots instead of processors.

• Logical processors against vCPUs per ESXi host

  Hello

  I am watching the host ESXi Configuration of maximum and to matters that I don't know what's the distinction between the logical processors for each ESXi host (160) and vCPUs per ESXi host (2048). Any explanation is greatly appreciated. Thank you!

  Hmm...

  OK I'll try to explain.

  1LCPU can be pinned to several virtual machines.

  If I have 1 quad core CPU, I have 4 LCPUs

  I can create as many virtual machines

  (1) 1 VM with vcpus 1

  (2) 1 VM with 2 vcpus

  (3) 1 VM with 4 vcpus

  1st VM will be pinned to 1 LCPU.

  2nd VM will be pinned on the 2nd, 3rd LCPU.

  3rd VM will be pinned to LCPU 1,2,3,4.

  If the processor reqquest comes from 1 VM and VM 3rd at the same time, she will be the process queue and do accordingly!

  I hope you have it now!

• Logical processors

  Hi guys,.

  Maybe this is a stupid Question.

  If I have a cluster that has 4 hosts. Each host has 4 x Quad Core Processors (not Hyper Threading), that gives me 16 logical processors for each host a total of 64 logical processors in my Cluster.

  Does that mean that I could create only 16 VMS with 4 CPU?

  Thank you

  VMware currently recommended as a guide for vSphere - 4-8 vCPUs per core - 6 usually. so a box Quad-cores should accommodate 96 VMS, assuming there is enough memort, disk and network - but you're right more resource consuption the virtual machine requires less of these virtual machines you can host on a single ESX/ESXi server - this is why it is essential to have the resources the VMS invited-

• HP DL360 gen9: logical processor of difference

  Hello

  I have a question about our DL 360 Gen9 server with windows 2012 r2 installed.

  On a single server detects the processor:

  Intel Xeon CPU E5-2630 v3 @ 2.40 GHz, 2397 Mhz, 8 Lossnay 8 logical processors

  While the other server with the same type and same operating system detects:

  Intel Xeon CPU E5-2630 v3 @ 2.40 GHz, 2397 Mhz, 8 Lossnay 16 logical processors

  Y at - it a setting or something I've missed, or it comes with the Board it self?

  Thaks,

  He solved, sorry.

  These Hyperthreading is disable, you must activate from the Bios.

• How do you calculate the logical processors in vmware

  When I see via Vcenter console to below two hosts:

  first host via vcenter console found Dell R900 there 4 physical CPU taken each socket supports 6 hearts. The Socket is Intel Xeon x 7640 it shows 24 logical processors.

  The second host via console found R910 Dell vcenter, she has 4 CPU sockets physical each socket supports 6 cores. The Socket is Intel Xeon x 7540 it shows 48 logical processors.

  why there is difference of logical processors. and how it was calculated.

  The difference is that on the second host hyperthreading is enabled - a logical processor is a physical core or the Hyperthreaded where a virtual cpu will be scheduled.

• How can I add processors in ESXi?

  How can I add processors in ESXi?  I have a quad-core processor, but once I allowed my server, it only allows me to use two now.  I guess I need another button, or buy some add-on?  I use ESX Server 3i, 3.5.0 123629.  Any help would be greatly appreciated.  I'm in love with this product!

  ESXi is licensed per socket. So 2 quads counts as two processors.

• What is a difference between 'Logical processors' and 'logical processors for each host?

  Hi all!

  In the official document VMware "vsphere-51-configuration-maxima" or "vsphere-55-configuration - maximums.pdf" in the section "ESXi host maximum rates------Maximums calculation" exists in the elements:

  "Maximum CPU------logical CPU for each host ' (vSphere 5.1: 160;)   vSphere 5.5: 320)

  and

  "Machine virtual maximums------virtual CPU by host ' (vSphere 5.1: 2048;)    vSphere 5.5: 4096)

  Question: what is the difference between the two?

  And a more complex thing to maximum rates:

  Virtual machines per host: 512

  Number of hosts per cluster: 32

  Therefore, the cluster may be Virtual Machines (maximum): 521 * 32 = 16384

  But in the document, we have only 4000 VMs in maximum.

  Why?

  Thank you

  Ramirez,

  I understand your question as difference between 1. logic virtual CPU vs / by the hosts and 2. cluster/host Max County VM.

  Consider the case below;

  2 servers ESXi - 20 mV

  ESXi taken 1-4, 2 cores / socket

  ESXi 2-8 Sockets, 2 cores / socket

  Now here number of CPU logic-(4 x 2) + (8 x 2) = 24

  20 virtual machines - 2 jacks, 2 core / socket

  Virtual CPU count - 20 x (2 * 2) = 80

  Hope your first confusion is clear now.

  And a more complex thing to maximum rates:

  Virtual machines per host: 512

  Number of hosts per cluster: 32

  Therefore, the cluster may be Virtual Machines (maximum): 521 * 32 = 16384

  But in the document, we have only 4000 VMs in maximum.

  Why?

  This means that even if you have 32 Guest and each host can accommodate 512 VMs each the maximum number of virtual machines per cluster may not exceed 4000. And it does not mean that you can have a maximum of VMS (512 * 32).

• Server has 80 logical processors, but I can only use 8 cores for a virtual machine

  We have a host of ESXi 4.1 with four 10 processors and we want to give a VM 20 vCPUs for a test, but I can choose only 2 virtual Sockets with 4 cores per socket or 1 virtual socket with 8 cores. What is the maximum I can do? I'll attach screenshots so you can see what I'm looking at.

  With vSphere 4.1 eight-way virtual SMP is the maximum that you can configure with the Enterprise Plus license. With vSphere 5.1 the maximum has been increased to 64 channels for businesses more (32 channels for the company).

• Support processor for ESXi 5.0?

  Our company is currently using vSphere deployed on ESXi 4.1 servers and we are looking to try out the new 5.0 before actually buying the upgrade, but we wanted a devil of a time finding a server it will run on. When I try to install on our servers, they say that the LAHF and SAHF CPU instructions are not supported on this processor. It's probably expect that the waiters are about 5 years, so I decided I would build my own server to test with. Looking at the page system requirements 5.0 ESX http://kb.vmware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1003661 looks like it is said the Intel Xeon 3100 series is supported.

  So my question is: is the supported Intel L3110 processor for sure?

  I got the specs on this processor from: http://Ark.Intel.com/products/32709/Intel-Xeon-processor-L3110-%286M-cache-3_00-GHz-1333-MHz-FSB%29

  You can perform a search in the hardware compatibility matrix below

  http://www.VMware.com/resources/compatibility/search.php

  But Ko say its taken care of, so it will be supported, give it a try and see... But as the hardware compatibility of vmware matirix said not his only supported on esx (i) 4.1 and lower version, could be the case, the HCL site is not updated. See the link on intel xenon 3100 and the version of esxi supported below

• Logical volume Read ESXi-Host - RAID level

  Hi all

  is it possible to read the RAID of a via PowerCLI ESXi host level?

  I would check multiple ESX hosts, if they are built on a RAID.

  Hello-

  You're not quite call things correctly.  There are 2 two different things you need to do:

  1. "point source" the .ps1 file in which the function is defined by doing something like: ".." c:\temp\functionDefinitionfilename.ps1 ".
  2. _then_, you must call the function name (not the name of the .ps1 file) and can pass parameters (such as "Get-VNVMHostLogicalVolumeInfo - VMHostName myvmhost0.dom.com"

  To article 0, you _must_ include the period and the space before the name of the file in which the function is defined.  This action is what makes the "Get-VNVMHostLogicalVolumeInfo" function available in your PowerShell session.  It is the "supply point".

  Then, for question 1, which is the function name, "Get-VNVMHostLogicalVolumeInfo", not the name of the definition of the function (the .ps1 file) file.  Until you do these two things, you will continue to get zero results.  You follow?

• Codec DivX 6.8.5 (4 logical processors) problem. Need help!

  
  

  Hi Yangtze,

  For the codec problem - I would recommend test avi different filters and see which works best.  To see what filters you have available on your computer, use the GetAVIFilterNames and this will fill a list for you.  From there, you can test to see which gives you the desired playback performance and compression.

  For the problem of Eve - in your VI, call an AVI fence and fence IMAQdx?   It sounds like you might not close all your references, and if you leave them open, even closing LabVIEW is not guaranteed that this.   Tryadding to your program.

  See you soon,.

• CentOS 5.5 100% CPU use 50% of the CPU of the host - very simple config

  Hello.

  On an upgrade on ESXi 4.0u1 - & gt; ESXi 4.1, I got a CentOS 5.5 32bits with VMware tools and local storage SCSI RAID5.

  Host: IBM x 346 Intel Xeon 3, 4 Mhz single core, hyper-threading, dual-CPU 10 GB of RAM.

  VM: CentOS 5.5 32bits, kernel 2.6.18 - 194.11.1.el5 #1 SMP

  VM resources: 4 vCPU, 4096 MB RAM, affinity and default limits

  I've got high utilization of the processor on this light apache + mysql box. In order to optimize the system, I came to this observation:

  -When my CentOS VM uses 100% cpu, the ESXi host uses only 50%

  My question is: why is it impossible to use more cpu, as this the only VM on the host?

  Clues or tips?

  TIA

  First of all, you have an absolutely incorrect configuration.

  You see 2 CPU * HT * 1 core = 4 logical processors in ESXi. But actually it's only 2 physical cores, and you should not give any VM on the ESXi exceeding 2 vCPU, because it isn't real processors and VM is not aware of it.

  If you have 2 virtual machines with 2 vCPUs each then Yes, HT will give performance gain, but not in this case.

• Processors logics esxi

  Hello world.

  I know there is a lot of documentation on the issue, but all the information that makes me feel even more confused.

  The question is simple: "in esxi 5.5" ".

  • NO HyperThreading
  • Intel Xeon CPU E5-2407 v2
  • processor 1 socket
    
  • Cores per socket 4
  • 4 logical processors.

  
  

  How many virtual machines can I run?

  I understand just 4. One by logical processors.  But I'm running 5, so I do not understand the question.

  
  

  Thank you all
  

  
  

  Hello

  the amount of virtual machines, you can run is more limited by the amount of RAM that you allocate to the virtual machines, since each VM you start needs at least little RAM to start.

  ESXi has no problem with the use of a logical basis for several virtual machines.

  When you create more and more virtual machines, each logical heart will serve X vCPUs. If it's good or not depends on your applications and their need for resources.

  I run up to 5 by heart logical vCPUs in our environment and it works well because the applications need a lot of time CPU.

• Problems use processor ESXi

  Hi guys -.

  IM new here and just installed ESXi 4.0 (latest one) on a 490 dell precision. So far, it has 2 GB of ram ecc, but I have another 2 GB on the way. Its got a 3.0ghz xeon dual-core processor with ht technology so it appears as 4 processors. Esxi installation went smooth and I've added a virtual machine in and begain to install Server 2008 r2.  To get to the point, it takes forever to install Server 2008 r2. I have no idea why. I'm looking for in table performance and its only operating at 20%. Why can't he just use more processor? or am I missing a setting?

  Before, I tried to install Server 2008 r2 just to see how fast it would install right hard disk (no esxi) and it took about 10 minutes to start cd to type the password for the first time. very fast.

  Why esxi it slows down a lot?

  Ryan

  Repeat the installation with a single vCPU assigned to the virtual machine and see what happens. Chances are you see some argument for resources by having all your Physics (and the HT "nuclei") assigned to the virtual machine.

  You can check the values of CPU ready to give you a good idea if you may be suffering from a CPU contention. On ESXi, this can be done using resxtop (part of the vSphere CLI), or changing the graphics options of the particular graphic performance for this virtual machine.
