• Virtual machine has 12 virtual processors, but the host only supports 8?

  Hi all I am using ESX 5.1 and have a machine Windows 2012 R2 Standard of virtual (vmx-09) comments that I'm moving to 8 processors to 12 processors.  But when I turn on the virtual machine after changing the UC 12 I get the error message

  "Virtual Machine has 12 virtual processors, but the host only supports 8. 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".

  Now, I know that 2012 R2 Standard Windows can handle 12 processors and I thought that ESX 5.1 could also, but I'm wrong?  This is the Standard of vSphere license 5.  Thank you!

  Hello

  vSphere 5.1 Standard license has a 8 vCPU per VM limit.

  Company = 32 vCPU

  Business + 64 vCPU

  You must upgrade to vSphere 5.5. This can be done with your vSphere license 5, as it is for all versions 5.X of vSphere and vCPU limit has been deleted in 5.5.

  So you can have as many vCPU per VM that your host has logical cores.

• Virtual machine has 8 virtual processors, but the host only supports 4... ?

  Hello

  My setup is a VSphere cluster with 4 guests each with:

  E5450 3.00 Ghz Dual Xeon Quad & 32 GB of Ram.

  I run a number of virtual machines, mainly Windows 2003 Server Enterprise. Most of them is running on 2 or 4 virtual processors.

  I tried to create a new virtual machine with virtual cpu 6 or 8 and 16 GB of ram. When I tried to turn on the virtual machine, I got the message below:

  Virtual machine has 8 virtual processors, but the host supports only 4. The number of virtual processors can be limited by the OS, etc...

  Now, I checked my licenses and they are for each host that I have:

  Company of VSphere 4. 1-6 cores per processor. 2 cpu by assigned host.

  Thus, it cannot be a problem with the license...

  Any ideas?

  Hello and welcome to the forums.

  The Enterprise Plus edition is required for vSMP 8 channels.  You can check in the vSphere editions comparison.  The Enterprise edition will be limited to 4 vCPUs.

  The 6 cores per processor refers to the ESX host itself and directly relate to the SMP virtual machine.

  Good luck!

• Impossible to allocate additional processors (virtual machine has 8 virtual processors, but the host only supports 4)

  Dear team,

  I want to devote 8 vcpu to one of the virtual machine, but it gives following error

  "Virtual Machine has 8 virtual processors, but the host supports only 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".

  want to know the weather, that it depends on the os under license or guest vm

  

  Hello

  It is the restriction of license. 4-way vSMP is the right thing, you stressed in your screenshot.

  If you upgrade your server and license to vSphere 5, you can allocate 8 vCPU with Standard license and 32 vCPU with your license of the company!

• Trying to increase the capacity of virtual resource Flash, no host esx and no SSD is located

  In vSphere 5.5 WebClient, click host esx-> settings-> virtual Flash Resource Management.

  Then click on the button 'Add ability '. Empty the list of hosts/SSD devices.

  I followed the instructions with this announcement, but the list of hosts/SSD devices remains empty.

  Anyone know how to get around this problem? Thank you!

  It works indeed. You need to do some CLI commands to mark the device as a local and an SSD, but I outlined the steps in a post on my blog:

• 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).

• HP MSA2324i, new volume / LUN added, cannot be seen by the host ESX 4.1 (fine old LUN work)

  Hello

  I have a vSphere Essentials Plus 4.1 cluster that is connected to 2 x bays HP MSA2324i SAN, we have 2 x hosts and both can see current volumes / LUNS absolutely perfect (vMotion and migration of VM offline all work as expected). I'm starting a consolidation project virtual disks / volume of the San 2 x, however a new volume I created on a network SAN cannot be seen by the other host.

  The new volume has been implemented exactly like the others, but of course with a unique logic for mapping unit number explicit, but when scanning the iSCSI HBA the new LUN is never found :-(

  I was wondering if others have had also this happens to them and know why this may be implemented?.

  (This is a company that I joined, it's my third week, and that they had also no VMware subscription on their reunification since 2012, otherwise I would be to connect a call to technical support of VMware, by train to get the sub upwards and running)

  OK I think that might be the cause, I came across this recently maximum LUN ID is 255, change the logic unit to a number smaller than 255 ID number and try again, let us know how you go!

  I'm looking for the method step by step for the migration of virtual machines to new host ESX Migration both cold and hot.

  Scenario - I have two data centers running ESX host stand-alone (with VM) in Europe. I need to build the new ESX host in new Dataceter to Singapore.

  Need prerequisites, the methods available for migrate VMWARE virtual has new host ESX (in the new data center) with minimum downtime.

  It will be great if you can enumerate the markets or redirect me to documentation that I can use to create detailed steps as the target host compatibility check on VMs and so on.

  The steps are correct. The virtual machine must be turned off (step 3).

• What is the best way to backup of virtual machines on a standalone ESX with the data store local

  Hello

  I want to save the virtual machines on a host ESX autonomous. and all of these virtual machines is the local data store.  What is the best way to save these virtual machines in this situation?

  And probably we don't provision VTL on the local data center, so it is possible to use VCB to backup? And VCB is a good choice compared to the traditional method that installs the backup client in each virtual machine?   Because I think that in this situation with the data store local, it cannot not reduced the load on ESX hosts and network overhead can be avoided.

  Thank you!

  LAN

  > 1. VCB usable remote tape library? I mean it's not local library and uses the tape library to another network data center.

  VCB is completely unrelated to the tape library, it is a framework, not a backup solution. If your standard backup software can work with the remote tape library you can try it to ungrateful with VCB.

  > 2. what the difference bwteen hot - added NBD and modes if there is that an ESX host with store data local and want to use a virtual machine like VCB proxy? I think that they are the same: the VCB proxy read data through the I/O of the ESX host stack in this situation.

  NBD works on network and the backup traffic goes through the service console connection. Hot add uses special machine for assistance to connect vmdk to and uses of e/s disk stack instead of e/s network.

  > 3. Veeam Backup is free software?

  No, it isn't.

• When you run a single virtual machine on the host computer, is it ok to assign all the processors for comments

  I have a single guest Windows 7 Pro running on the host ESXi 5 U1.   It will always be in a 1-1 configuration (we needed server hardware, but with BONES desktop for purposes of licensing).  The host CPU is an E5603 (Quad - core 1.6 GHz).  I want the guest to have the maximum amount of possible processor cores, because a true multi-threaded application runs.  Because Windows 7 is limited to 4 cores, I disabled hyperthreading on the processor so that when I assigned 4 cores the VM, I get all 4, not the half because of hyperthreading.

  I am setting for claim processor between the host and the guest?  Should I only assign 3 carrots to the guest while it is still available for the host?

  With the requirement, it's guessing more than knowing what to configure. I think that with 2 Dual-Core configuration, I suggested above, you're on the save side.

• After the installation of Solaris 10 for x 86 U4 on my server ESXi 3.5, the host Solaris keeps restarting over and over again, no matter the type of virtual processor I choose, x 32 and x 64 both fail.

  I have this looked across the net and found a reasonable reason he could because of the bad virtual processor, but regardless of the x 32 or x 64, they keep them he shut down and restart all the time. could you give some help on this.

  and ideas would be very appreciated.

• Adding more than one host ESX and the upgrade at the same time.  What is the order of preference of the operations here?

  We are budgeting for more licenses and hardware for 2014 and want to do immediately in January.  I am trying to decide what is the best order of operations for adding two vmware hosts additional to our current installation of vsphere and also upgrade our vsphere / esx 4.1 u3 for the latest and best.

  We have 3 Dell PowerEdge R710 running ESX 4.1 U3.  In this vmware cluster, there is a vcenter server 4.1 U3 virtual machine handle this.  The three servers are about 90% memory used so we add 2 additional servers.  Probably the Dell PowerEdge r.620 since we get up 2 in the space of a 710.  Storage is on a san EMC NX4 NFS which will become too but not yet, let's just deal with the vmware part.

  When adding additional r.620 2, should I install ESX 4.1 on them and join them to the existing cluster and THEN pass vcenter and each one esx?  I ask precisely because 90% of use on 3 current servers, I need 2 other servers to support the update operations take place.  They would be able to repel vmotioned vm while each host receives an upgrade at the same time.

  So which is the best way to go about adding of the hosts and the upgrade?  Would I add as 4.1, then they would be available as targets vmotion and so I have room to start the hosts one upgrade at a time?

  If I update vcenter to the latest version, it is comparable backwards and can manage the 4.1 hosts, but also hosts 5.x?  I guess version 5.5 is the last one I would get from VMWare?  It is right of ESXi, then, how is this ESX ESXi 5.5 4.1 upgrade?  How much storage space do I need for ESXi 5.5, as I'm dechatoiement out of these r.620 Dell and need to know what hard drive to put in.

  The steps that you must follow

  -Updated vCenter Server

  -Upgrade of the ESX hosts (because we do a updating of the material we will install 5.5 on our new guests and add them to the cluster and then dismantle our existing)

  -Upgrade VMWare tools

  -Update data warehouses

  ESXi 5.5 has these storage requirements:

  • Installing ESXi 5.5 requires a boot device is at least 1 GB in size. When booting from a local disk or SAN/LUN iSCSI, a 5.2 GB drive is necessary to allow for the creation of the VMFS volume and a scratch 4 GB partition on the boot device. If a smaller drive or logical unit number is used, the installation program attempts to allocate a region scratching on a separate local disk. If a local drive is not found, the scratch partition (/ scratch) is located on the disk virtual ESXi host, linked to the/tmp/scratch. You can reconfigure /scratch to use another drive or logical unit number. For best performance and memory optimization, VMware recommends that you leave no /scratch on the ESXi host ramdisk.
  • To reconfigure / scratch, see Configure the Scratch Partition of vSphere Client vSphere Installation and Installation Guide.
  • Because of the sensitivity of the I/O devices, USB and SD, the installation program does not create a partition scratch on these devices. Therefore, there is no tangible benefits to the use of the great features of USB/SD that ESXi uses only the first 1 GB. When installing on USB or SD, tent Setup devices to allocate a region scratching on a local disk or the data store. If no disk is local or data store, /scratch is placed on the virtual disk. You must reconfigure /scratch to use a persistent data store after the installation.
  • In Auto deploy facilities, Setup attempts to allocate a region scratching on a local disk or the data store. If no local disk or data store is found /scratch is placed on the virtual disk. You must reconfigure /scratch to use a persistent data store after the installation.
  • For environments that start from a San or use Auto Deploy, it is not necessary to assign a separate logical unit number for each ESXi host. You can co-locate areas scrape for several hosts ESXi on a single LUN. The number of hosts assigned to a single LUN must balance the size of the LUN and behavior I/O virtual machines.

• Maximum processor for each virtual computer cores

  Hello

  I need some advice on the maximum number of CPU cores that we assigned to each virtual machine, as well as the maximum number of processor cores physical on the host machine.

  I stumbled on some features of mention about the virtual processors and virtual cores.  Are they referring to the same thing?

  1 virtual core is equivalent to how many physical basis?  1 virtual CPU is equivalent number of physical CPU or core?

  Appreciate your kind reply on above.  Thank you.

  Concerning

  cleohm

  On ESX 1 vCPU is a logical basis.

  It is a heart in a CPU socket, but could also be logical fundamental of a core (if you have HT enable).

  On ESX/ESXi 3.5, there is a limit of max 4 vCPU for each virtual computer.

  On ESX/ESXi 4.0, there is a limit of max 8 vCPU for each virtual computer, but you will need virtual hardware 7 and a license of the company more

• The ideal comments processor for a CPU i7 3820 host settings?

  Hello world

  I use a Windows 7 (x 64) computer that uses a processor Intel Core i7 CPU 3820 (@3.6 - 3, 8 GHz). The processor consists of 4 physical processors and a total of 8 logical processors.

  

  I noticed in VMware Workstation (10 v) that there are a number of settings of the processor for the guest operating systems. I can only imagine that different guests work best with a variety of settings of the processor.

  Of particular interest to me optimizes the processors for XP (SP3), Windows 7 (x 64) and invited Windows 8.1.

  If anyone can shed some light on the following comments related issues processor it will be greatly appreciated-

  (1) 1) which is the ideal combination of the 'number of processors' versus 'Number of cores per processor', for example: if I want my guest to run with 4 cores, is it better to have one), or b) after?

  one).

  

  (b).

  

  I noticed that none of the guests accept the settings below (However, I suspect that the limitation is in fact with the guests of CPU!).

  

  (2) with regard to the "Preferred Mode" setting under "virtualization engine" section is each any merit using one setting other than "auto"? Assuming that there is a preferred mode, so what's the preferred mode for my host CPU?

  

  (3) what is the effect of tick "disable acceleration for binary translation"?

  

  All the answers to the above questions will be greatly appreciated.

  Kind regards

  It makes no difference.

  Consumer versions of Windows won't make use of more than two takes.  The virtual machine should work correctly, but you two completely inactive vCPUs.

  (2) with regard to the "Preferred Mode" setting under "virtualization engine" section is each any merit using one setting other than "auto"? Assuming that there is a preferred mode, so what's the preferred mode for my host CPU?

  

  The automatic setting is intended to be the most powerful.  However, in some cases, it is not.  For modern Windows clients on your CPU, the Auto selection will be Intel VT-x/EPT.  While EFA (extended page tables) provides the best performance for most workloads, it suffers from a large fine of TLB miss.  If your workload is a TLB (e.g. specjbb) buster, so you might get better performance without EPT.  Binary translation can be a victory for some workloads on 32-bit Windows XP, due to frequent bouts of TPR.

  (3) what is the effect of tick "disable acceleration for binary translation"?

  

  Normally, the binary translation only applies to the kernel code and user code runs directly on the processor.  If you disable acceleration for binary translation, all the code will be run using the binary translation.  The result will usually be catastrophic performance.  Why would you do?  Due to the nature of binary translation, some things aren't quite reason code user running directly on the processor-level.  If your applications are particularly sensitive to these differences to run natively, you may need to disable acceleration if you want to use the binary translation.  On hardware that supports Intel VT - x, hardware-assisted virtualization is usually a better option than VT without acceleration.
