• Allocation maximum vCPU for Windows Server 2008 Enterprise running on vSphere 4 Enterprise (ESXi 4.1)

  Hello

  I have a guest of Windows Server 2008 Enterprise (x 64) running on ESXi 4.1 with a vSphere Enterprise license 4. I believe that the comments and hypervisor should be allowed for and support 8 virtual processors, but when I add more than 4 and try to turn on the virtual machine, I get "market of the VM [virtual computer name] Virtual machine has 8 virtual processors but the host only supports 4. The number of virtual processors can be limited by the selected guest OS for the virtual machine or the granting of licenses for the host".

  The selected guest OS is 'Microsoft Windows Server 2008 (64-bit)'. There is no option in the drop down menu to 2008, Enterprise Edition.

  This configuration is actually supported? If so, what should I do to get it working?

  Thanks in advance,

  Matt

• 5.5 vCPU Maximum for Standard and Enterprise editions

• vCpu limit reached - should get more with 3.5 U4

  Hello!

  I first tried to start more than 128 vCpus on a host base 16 (DL580 G5) running ESX 3.5 U2.

  I did an upgrade on ESX 3.5 U4 and waiting for a change in the maximum vCpu by the basic limit.

  But what is always the same. When I try to turn on too virtual machines (100 ~ VM with ~ 128 vCpus) I get the message that the vCpus running maximum is exceeded.

  I'm quite confused that the max Vcpu by heart would have had to change with U3 3.5 to 20 by heart.

  Thank you very much for your help!

• vSphere virtual integrated cpu speed limit?

  Hello

  I have a group of four vSphere 4.0u1 guests with many free resources (4-core nehalem 2.27 GHz + 32 GB RAM for each host). There is a virtual machine (linux Debian 5, 64-bit) with one vCPU. Though this VM would have more speed CPU (trigger alerts on the CPU usage), it becomes ever more than 2 GHz. In the resource pool, I tried to add several actions (up to 8000), but without success

  Is there a speed limit of vCPU in vSphere so that the computer only vay to increace pover of VM is to add an another vCPU? Or am I missing something basic, where can I put the maximum vCPU for all my virtual machines? I think vCPU shloud be scalable in DURATION up to 4x2.27GHz less what console service needs, while the other usingVMs of lesscpu must be migrated to other hosts by the Drs Is is it true or not?

  Thanks in advance,

  David

  Hello

  You'll never be more than the power of one heart for each vCpu. At any time, each vCpu is attached to a physical core. The ESX Planner do not aggregate the power of multiple processors to "emulate" a super processor.

  In your configuration, will have no more than 2.27 GHz each vCpu.

• vCPU Maximum

  If I have a 10 carrots on a physical host (ESXi 5). VCPU how much MAXIMUM can I connect to a virtual machine. If only a virtual machine is located on the ESXi host.

  Take a look at Hi, I have 10 carrots on my ESX so what is the number of cores, I attribute to a single virtual machine running on the host computer? where I just responded to a similar question.

• maximum of vCPU with ESXi

  Hello.

  We have an application on redhat with hight cpu utilization.

  For now, we use the server with 4 QuadCore CPU, then 16 core.

  We believe the use of virtualization for this application.

  I see the standard ESXi license has limitation of 4vCPU...

  Can I make a virtual machine with 16 vCPU with ESXi or vmware product?

  There's a special permit for this?

  Scalability is good? Or it is better not to use vmware for this use?

  Xavier has ++

  Xavier-

  8 - way SMP is currently the maximum supported by ESX and which will require the product under license (i.e. not 'free' license). There are speculations that this number will 8-way beyone in the next version, but there is no guarantee. Typical applications of virtualization are scale-out, not measure - upward for this reason. However, you can assign only 8 lanes practically in several ways:

  1 x 8-core vCPU

  2 x 4 vCPU strands

  4 x vCPU 2 strands

  8 x 1-core vCPU

  Use the advanced cpuid.coresPerSocket setting to configure. I have more details about it in my blog:

• Maximum number of VCPU

  Hello.

  What is a maximum number of vCPU per VM on esx3.5?

  I thought that this depends on number of hearts on pchysical cpu, but some told me other things.

  Thank you

  4-3, 5 - If you upgrade to vSphere, you can go beyond depending on the license, but you must be careful when linking to a large number of vCPUs are you likely to encounter problems with CPU scheduling.

• What is the maximum number of vCPU can I connect to a virtual computer?

  Currently, we are conducting a cluster of 3 ESX host.  2 of them run Xeon Dual Core Pro 7140 M and the rest works a Quad-Core Intel Xeon X 5460 CPU.

  HT enabled processor Xeon Dual Core Pro 7140M.  In this way, each female, it shows that 4 logical CPU.

  We would like to know if we can assign 4vCPU to a virtual machine (as required by a server administrator) WHERE we can assign only 2 vCPU maximally?

  Thank you

  I think you should spend some time reading about VMware resources management guide and have a good operation of a CPU scheduling understandings and best practices dealing with vSMP.  As everyone says, it would be unwise to have a virtual machine running 4vCPU or 8 vCPU and I did not see a need for anything that is 8 vCPU but does not mean that it cannot.  It would be nice if you can tell us your current use of the server/application and details of the charge and that would quickly determine 2vCPU is pretty good.  The vCPU more assigned to the virtual machine, takes more time to achieve your requests because it must have enough carrots to do and called "Co planning."  I have attached the guide so that you can read a few details.  http://www.VMware.com/PDF/vi3_35/esx_3/R35/vi3_35_25_resource_mgmt.PDF

  It wouldn't surprise if you complain about performance issues when you have tons of 4vCPU or virtual 8vCPU running in the cluster.  Always start with 1vCPU and growth like him.

• Maximum size LOG_BUFFER

  Hi guys,.

  I have a question about the LOG_BUFFER initialization parameter. What is the maximum size allowed for this value? I got some online forums that high values does not benefit a lot, but there is no harm in spending. What I have is a very huge table updated - that I am segmentation using parallelism DIY (from Tom Kyte) and execution of 5-6 pieces at a time. During the execution, most expect the reported event is on "log buffer space" event. If I understand correctly, it is either because of the disks slow log or a bad tuning log_buffer. Before entering disk speeds, I would get clarity on LOG_BUFFER.

  Now, I tried to increase the value, but no matter what value I give in the init.ora file, does not 'see the log_buffer parameter' above 268427264 (I think it's almost 256 MB). I tried to give 2GB in the init.ora file, but it does not exceed 256 MB. How did this upper limit calculated by Oracle? And how can I increase it?

  Could you please help?

  Oracle version: 11.2.0.3.0

  OPERATING SYSTEM: IBM AIX 7.1

  Number of cores: 4; Number of VCPU: 4; So that gives 16 processors

  RAM: 40 GB

  SGA_MAX_SIZE: 15G

  SGA_TARGET: 0

  PGA_TARGET: 1 G

  If you need more info, please let me know.

  Directly from the documentation.

  You won't get more 256 MB

• Maximum number of virtual machines by free ESXi hypervisor?

  Community of VMware,

  I just installed the free 5.5 ESXi hypervisor and I wonder if the same virtual machine limits apply to the stand-alone scenario as vCenter? Can I run actually 512 VMs? What, if any, is the maximum number of virtual machines, I can run on a free version of ESXi?

  From 5.5 ESXi limits most have been removed, but only a limit of 8 vCPU per VM remains. So if I'm wrong, the VM 512 mentioned for each host (see http://www.vmware.com/pdf/vsphere5/r55/vsphere-55-configuration-maximums.pdf) affect the free hypervisor.

• Limit of vCenter Server Essentials 5.0 vs 5.1 vCPU

  Hello

  There currently restrictions during execution of vCenter Server Essentials in terms of vCPUs 5.0? For example I manage 3 guests by vCenter Server, each with 2 physical processors; (20 carrots/host) send me carrots close to 60 who manages a single Server vCenter.

  How about on 5.1 vCenter Server Essentials? I went through each document maximum Configurations for each version or stipulates a limit for vCPUs managed by a single vCenter, but this does not take into account license.

  Thank you and best regards!

  Hello

  you are not limited in the total number of cores. (well an Essentials kit houses 3 with 2 Sockets each, your base number max would be so [max available by socket hearts] x 2 x 3)

  The license only limits the number of vCPUs that you configure for a single virtual machine. And it comes to 8 vCPU per VM in vSphere 5.0 and 5.1 Essentials.

• Determine the use of vCPU using PowerCLI

  Is there a way to determine how many vCPUs uses makes it a virtual machine using PowerCLI?  For example, suppose you try to size just your virtual machines with powerCLI.  If the virtual machine uses several threads, it can use the multiple vCPUs.  If it is mono-thread, it can only use one vCPU even if she has a high workload.  You can determine what virtual machines have multiple vCPUs but use less than they are allocated?

  As much as I know there is no meter that indicates if a core is used or not.

  What you could do, is the use of the CPU, and then check if the assigned processors are required.

  For example, suppose that the average CPU usage is 25%, and the maximum is 50%.

  If this VM has 4 processors assigned, you may deduct 2 CPUs would be sufficient.

  But this isn't an accurate calculation.

  Once you lower the processors assigned to the virtual machine, you will need to see if there's an obvious increase of the ready time.

• License question: with the help of two "Standard Edition" licenses for > 8 vCPU by host

  Hi, I've been reading place on it for a few hours and would like to get confirmation here.  I have

  -a physical host: dual processor, 8 cores per processor

  -multiple licenses VSphere 5.0 Standard edition

  -VCenter 5.0 Enterprise Edition

  I want to distribute the VM with 12 vCPU and I expect to consume two licenses Standard Edition - one for each CPU, for a total of 12 vCPU.  When I try to do using VCenter I get error "virtual machine has 12 virtual processors, but the host only supports 8.»  "The number of virtual processors can be limited by the OS selected for the guest virtual computer or licensing for the host."

  I think that it is a license restriction because on the same host, the VSphere evaluation has authorized the deployment of a 12 virtual machine using RHEL 6.3 vCPU.  I checked later vCPU on evaluation copy function and it was 32 channels for it proves that it is not a BONE or a physical problem.  I think I downloaded an evaluation of the 'norm' rather 'Enterprise', but I am not sure.

  I read compare VMware vSphere editions and the 'Standard' column has CPU line: "CPU 1" and line vCPU: '8 - way '.  This makes me think that, for each new license, I should have a CPU with up to 8 cores.  that is by consuming two licenses, I use 2 CPU and up to 16 cores.

  I also read the EULA VMware multi-core pricing and Licensing Policy , and he said:

  Software licenses with six (6) cores per processor

  It does not say "with hearts of six (6) software licenses by host '

  The following excerpt from the EULA is the only evidence that I could find to support the conclusion that for Standard Edition, the maximum number of vCPU for each host is 8 (regardless of the number of licenses consumed);
  Combines VMware licenses on a single host software. Licensing policy allows combining the even on software licenses uniprocessor.

  Someone can confirm the limitation and is there something obvious that I missed to compare VMware vSphere editions.  The difference between host and per processor is huge, I'm surprised that it is ambiguous.

  Thank you

  Looking at this picture, it is said that you need 1 VMware Standard license per physical processor that your host has.  Down the chart to the vCPU, who said that a VM can have at most 8 vCPUs (for Standard).  Isn't 8 vCPUs per license, which is 8 vCPUs total.

  The demo version is licensed Enterprise Plus and develops of vCPU 32 on a virtual machine.
