• VMs migration of a non - CVS to EVC cluster cluster

  Hi all

  Host	Processor family	Processor	Version ESX (i)
  Host1	Penryn	Xeon E5450	4.0.0 update 2

  I'm looking to create two groups, one for the three hosts of processor Penryn (dev) and a separate for six guests Nehalem/Westmere (prod).

  If I put one of the hosts Nehalem in maintenance mode, remove the current cluster and place it in a new cluster with EVC lit with the CVO 'Nehalem' mode, I will then be able to vMotion VMs to two other guests the current to the new EVC cluster cluster Nehalem activated?

  I understand that the virtual machines on the hosts Westmere must be powered off before their migration to the new Nehalem EVC cluster but can I Motion VM hosts to the new Nehalem Penryn cluster virtual machines?

  Also the guests of Nehalem contain two types of processors: X 5550 and X 5560. This would impact on virtual computers fast vMotioning of a non - EVC cluster to a new cluster of Nehalem VCA?

  TIA

  Yes. You go from Nehalem, Nehalem, no problem.

  "I understand that the virtual machines on the hosts Westmere must be powered off before their migration to the new Nehalem EVC cluster but can I Motion VM hosts to the new Nehalem Penryn cluster virtual machines?

  Yes. As long as the instruction set is lower or equal to Nehalem, you can do.

  As long as the non - evc cluster is Nehalem(or lesser), it shouldn't be a problem. Everything you do with CVS is hide which instruction sets may be available to virtual machines.

• EVC cluster creation / migration hosts him / minimal disruption VM

  I am reshape my somewhat environment and need a bit of advice.  Currently, I have 2 ESX hosts in a non - EVC cluster and built a new blade server.  The new blade and 2 hosts will work together in a cluster active CVS.  I know that I have to run my EVC cluster "Intel Xeon Core 2" mode.  All 3 hosts will support this mode.

  The News / 3rd cluster is sitting in his own vCenter, a VCA-activated cluster (in mode above).  Has no running VMS, it is already configured with network access and storage that matches that of the 2 existing/production hosts, which are currently managed by another instance of vCenter (but I am moving them out of this instance of vCenter in this new EVC-activated, to join the new blade.

  All hosts running ESX 3.5 U4.  vCenter is 2.5 U4.

  BIOS on guests must be modified to memory XD in so that they can be used in an EVC cluster, so I know I need to stop at SOME point to get them in the cluster active CVS.

  I have an idea on how to address these requirements, with a big goal is NO interruption of service for running virtual machines.  VMs can be migrated to a new cluster, EVC-activated, coming from an old cluster VCA not compatible?  Most all current VMs based on Intel some running already in reference "Intel Xeon Core 2" EVC mode or I'm just kidding me and must arrest all of them at some point after they "seized" a VCA-activated cluster?

  How would you do to this migration between vCenters and Clusters?  I think I can use 'Disconnect' the first vcenter (to at least avoid having to go into Maint Mode and then 'delete' of the first cluster/vCenter database)... also, I'm looking for the most logical get "here" to "there".  Thank you.

  I see that the problem of different vCenters/Clusters is resolved.

  What you need now is to know if you can VMotion between two ESXs with different processors. Before existing VCA, I have had... and had NOT a few difficulties doing this. It is not a problem when DIFFERENT pCPUs have the SAME GAMES of INSTRUCTIONS (SSE3, SSSE3, SSSE4 and so on...) Even if the sets are different, I was able to mix the MASK of CPU management options, which are by VM (thing that I didn't like... There should be an option to change this on a same CLUSTER basis or an ESX!).

  I recommend you to test for differences between the sets of instructions of the Jepp of two ESX with this tool, I think it is the best out there:

  http://www.run-virtual.com/?page_id=155

  If the sets of instructions are different, you have a problem, because you have to find the bits change in the MASK of CPU options in each virtual machine... and who needs a reboot, too. I think they will be different, because more recent pCPUs with FlexMigration (VCA compatible Intel processors), simply because they are new they surely have a new instruction set (perhaps SSSE4)

  Good luck!

• Active EVC cluster will not allow guests to reach...

  Recently, I installed a new vCenter Server 5 (vCenter 4.x running on a 32 bit OS then upgrade was not an option-fresh install)

  I had 1 main cluster in the datacenter with HA and active CVS. All 10 guests were very well in it.

  However, when the new vCenter Server has been up - and after having removed the old vCenter data center, when I went to add the host to the cluster (same as before active EVC mode) 6 guests joined very well, while the other 4 could not.

  Everyone knows this? Just a reminder:

  new vCenter Server 5

  all 10 guests were in an EVC cluster well

  4 of 10 guests will not join the same cluster...

  Thoughts?

  Hi xxx,.

  Another question regarding VCA - if I point the old vCenter DB, the new vCenter server will this cause problems because a new database created for the new vCenter? How should I approach the issue?

  You can't do it now, you can not connect vCenter 5 dB in the version of vCenter 4, different schema, tables etc. as I said in my previuos reviews, you must migrate to vSphere with DB 5

  1. Start vCenter old (I hope that you did not remove or disconenct any server from there, right?)

  If you do not make any changes to the OLD vCenter vCenter should be able to connect to the return ESXi hosts and apply all the settings (including the CTS)

  And Yes, I take off (unplug the old vCenter servers... so I guess that reconnect the old Server vCenter is not possible.)

  If you simply disconnected the old vcenter ESX hosts (not deleted) you should be able to connect to vCenter old with old settings, but as I said earlier, I don't know what will happed with a VCA base (because you creted clusters with different CVS on new vCenter.)

• Changing the Mode of EVC Cluster for guests of Intel

  We cross a turnover of rental for our ESX host that puts out some old CPU architectures. Once we get rid of these hosts, we will be able to raise our EVC Cluster mode.

  (1) once ready, are there special precautions to take before changing the Mode of EVC Cluster? Then I just change the setting?
  (2) when the VMs will begin taking advantage of the new architecture CPU (a reboot will or VMs must they be turned off)?
  (3) any question with VM do not be put off for long periods of time after the VCA mode change?

  (4) all other things to worry about?

  If I raise the EVC mode, virtual machines will be able to access the new features available in this mode?

  Is that you turn off and then turn on the virtual machines. A reboot of the guest operating system is not enough. A virtual machine determines which functions are available to turn on and cannot access all the new features that are added until the power is turned off.

• can we add L5420 and E5649 CPU model enable EVC cluster server

  Hello

  Cluster HA, we have 2 Guest ESXi 4.1 and model of processor are L5420 and E5649, and I am not able to Enable EVC mode.

  Please suggest how we can activate CVS my cluster

  Hello

  Theoretically, these two processors operate in the same cluster if you enable CVS for Intel host and select the profile "Penryn" Gen:

  

  In the case where you have not seen this, here are the compatibility matrix: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1003212

• Problem with moving of hosts with EVC cluster active

  I have 3 servers Intel cluster with EVC mode.

  I don't have a server in the cluster, and it is exactly the same as a single server in cluster (E7320 CPU)

  When I try to move this clustered server I get the error: the host CPU hardware does not support CVS on cluster?

  Thanks on help

  Have you already double check the BIOS settings. Intel-VT, Execute Disable Bit... This should be the same for all hosts.

  Are the hosts of the same provider? Same models =?

• Quick vMotioning problem between two servers HP BL460c Gen 9 when EVC enabled

  I have two HP BL460c Gen 9 blades configured exactly the same thing with 2 x Intel XEON E5-2660 v3 processors in each of them. Both running the same version ROM (I36 06/05/2015) and running the same version of ESXi (5.0.0 build 2509828). They are managed by a Server Build 2656067 vCenter 5.0.0.

  When I configure these two servers in a cluster with EVC disabled I am able to vMotion between them. However, if I activate the Intel EVC modes so I am unable to vMotion between these two identical servers.  Here is an example of the message that I get when I updated Westmere VCA mode

  Host CPU is not compatible with the requirements of the virtual machine to CPUID level 0 x 1 'ecx' register

  Bits of the host: 0000:0010:1001:1000:0010:0010:0000:0011

  Required: x 110: x01x:11 x 1: 1xx0:xx11:xx1x:xxxx:xx11

  Inconsistency detected for these features:

  * General incompatibilities

  If I disable CVS, then I can vMotion VMs between them.

  I wanted to add these hosts to an existing cluster configured with EVC Westmere mode so that I was able to vMotion between old and new guests, but was unable to vMotion VMs off the new hosts, even if I tried to vMotion to another new host.

  Configure a new cluster with only these two new hosts to so I could experiment. I can only vMotion between them if CVS is disabled. I cannot further increase the VCA mode on this new cluster, for example of Westmere to Sandy Bridge then I have virtual machines under tension within the cluster. For example: I put the VCA mode at Westmere, feeding on a virtual computer, when I go to change the CVS to Sandy Bridge mode I get the following message, I should be able to increase the VCA mode but may not lower it

  The cluster cannot be configured with the selected Enhanced vMotion

  Compatibility mode; The CPU features disabled by this mode may be currently in use

  by slot voltage or suspension of the virtual machines in the cluster.

  I get this message even if I try to set the VCA mode at the same level, that it is already.

  Anyone got any ideas on how to solve this problem?

  Hello

  Seems, your CPU supports 5.0 ESXi and vCenter 5.0, you must upgrade your vSphere vSphere 6.x for the VCA.

  See the links below and also compatibility VCA matrix attached:

• HA Cluster and vMotion CPU compatibility

  Will be the following servers and work of the processor all in a HA Cluster with ESXi embedded 4.1 with vCenter 4.1 vSphere?

  Reference Dell 2950 III Xeon E5410 @ 2.33 GHz

  Reference Dell R610 Xeon X 5550 @ 2.67 GHz

  Reference Dell R710 Xeon X 5650 @ 2.67 GHz

  Or will I have to activate the VCA Mode on the Cluster?

  Is there a chart that shows you what processor works in a HA Cluster and vMotion?

  You need a CPU mask on the VM vCenter migrating to the EVC cluster and adding one would require a reboot.  You can do instead.

  (1) create new cluster with appropriate VCA setting.

  (2) (2) migrer migrate virtual machines from one host, put it in maintenance mode and then move it to the new cluster.

  (3) stop vCenter.

  (4) connect to the host that was running with the vSphere client vCenter.  Unregister the virtual machine.

  (5) connect to the host in the new cluster, to save the VM vCenter and turn on.

• vMotion works between HP DL380 G7 and the Gen9

  Hi all

  VMotion I would like to know how working with HP DL380 G7 HP DL380 Gen9?

  Can someone help me?

  vMotion between this two servers:

  HP DL380 G7:

  Intel Xeon E5649

  Embedded NIC 4x1GbE

  + NC364T PCI Express Gigabit QuadPort

  HP DL380 Gen9:

  Intel Xeon E5-2650v3

  Embedded NIC 4x1GbE

  + 10 GB 2-port 10GBASE-T 533FLR-t HP FlexFabric

  Can someone help me?

  I would be very grateful
  

  Ralf
  

  The G7 has a CPU of generation Westmere, the Gen9 has a generation of Haswell CPU.

  vMotion requires that you have the same subset of games of CPU instructions and common on the source and destination of the CPU and active features in the server BIOS.

  This means that in your case:

  You will be able to vMotion virtual machine that has been powered on the host of the G7 (VM runs with Westmere instructions) for the Gen9 and so (but only if you don't re - power cycled the VM on the host G9).

  But you will not be able to vMotion virtual machine that has been powered - we on the Gen9 host (VM runs with Haswell instructions) to the host of the G7 most old car is missing these more recent CPU instruction sets.

  VCA comes here. By activating EVC on the common cluster with the generation of CPU down (in your case Westmere), all guests will present only these instruction sets to virtual machines when they are powered - on, which makes possible dynamic migration through the different physical CPU generations.

  See the following articles for more information about CVS:

  VMware KB: Enhanced vMotion compatibility (EVC) support processor

  VMware KB: EVC and CPU compatibility FAQ

  Alternatively you could manually hide CPU instructions by VM - with advanced options if you don't have a source host and destination in the same cluster, but it is a tedious task and I would not recommend it.

• The processors for vMotion compatibility

  We have just upgraded to vSphere Essentials 6, Plus so we can take advantage of vMotion. We have built an almost exact replica of our existing Dell PowerEdge T420 server, so that we can have a high availability for virtual machines, they move from one physical server to another, depending on the needs. Looking through the documentation of DRS cluster, it is said that the processors 'must come from the same class of supplier (Intel and AMD) with the same family of compatible processor for migration with vMotion. . "(vSphere 5.5 Documentation Centre()'

  Our current server has a processor of v2 Intel Xeon E5-2440 (8 cores, 20 MB of cache, 1.9 GHz). The seller we buy our new generation of server of door the same CPU model number (Intel Xeon E5-2440), but with 6 cores, 15 MB of cache, 2. 4 GHz. They have to special order the exact same processor, we currently have. We will encounter any problems if the rest of the hardware is the same, but the processors are slightly different? Same supplier, same family, same model number – only with fewer cores, less cache, more GHz. Is that what I should consider before moving?

  Thank you!

  Ben

  Your processors are of different generations, the E5-2440 is a Sandy Bridge and the E5-2440 v2 is an Ivy Bridge, take a look here: http://ark.intel.com/compare/64612, 75263

  And since they are from a different generation, you need to activate CVS in your cluster to the power of the machine virtual vMotion between these hosts, have a look here for more information on the CVS: KB VMware: best vMotion compatibility (EVC) processor support

• Regarding vSphere VCA and vMotion

  Hi all

  I have several questions about vMotion and VCA, can anyone help?

  1. If I mix several types of CPU (from the same supplier of CPUS) in a vSphere without EVC cluster active, what will happen? can I vMotion VM on the host?

  2. I can vMotion VM Cluster with older CPU for the Cluster with more recent CPU? Assume that CVS is not activated on the two groups.

  3. can I vMotion VM Cluster with older CPU for the Cluster with more recent CPU? Assume that CVS is not enabled on the source cluster, but active on the destination Cluster.

  4. I can vMotion VM Cluster with older CPU for the Cluster with more recent CPU? Suppose that EVC is enabled on the source cluster, but not active on the destination Cluster.

  5 can I vMotion of virtual machine of a stand-alone ESXi host on an active EVC cluster? Assume that the CPU is the same.

  6 the KB "EVC and CPU compatibility FAQ" below, if we disable CVS on a cluster, the virtual machine can only be migrated to hosts with CPU even or more.

  Why virtual machines is only able to move to other ESX/ESXi hosts that are in the same generation of CPU or more? It's in front of my knowledge.

  VMware KB: EVC and CPU compatibility FAQ

  What is the impact on vSphere features of the Cluster when I turn off the CVS mode?

  To turn off the CVS on a cluster mode, it affects vSphere Cluster features in the following ways:

  • vSphere HA (High availability): vSphere HA is not affected because of the cyclic power failover virtual machines when you start on a new host. This allows the VM picking up the new ID CPU and it allows to start without problem
  • vSphere DRS (Distributed Resource Scheduler):
    • vMotion: virtual machines is only able to move to other ESX/ESXi hosts that are in the same generation of CPU or more. If the DRS is configured for fully automated, this can result in virtual machines, eventually migrating to hosts on the cluster with the generation of CPU more old where they cannot be moved via vMotion on different hosts with a newer processor generation.
    • Storage vMotion: virtual machines are able to be moved to Storage vMotion with EVC mode disabled in a cluster
  • Location of the pagefile: it is not affected.

  Thank you.

  1. If I mix several types of CPU (from the same supplier of CPUS) in a vSphere without EVC cluster active, what will happen? can I vMotion VM on the host?

  (a) you very well can vMotion virtual computers between the hosts with identical processors within the cluster.

  (b) for vMotions on different hosts, it depends on CPU instruction set parity and orientation, i.e. the older generation-> new generation or vice versa.

  Consider the following: when a VM is turned on at the start, it is presented in UC sets from the physical host, where it has been turned on. It must keep these settings until the virtual machine is turned off, any host it is migrated to in the meantime. Therefore, as long as a host provides these CPU instruction sets, it can be vMotioned it. Further instructions on new hosts games is irrelevant for this and just hidden-away of the guest. So old-> new should be fine, but new-> old most likely will not work because the virtual machine works with games of additional CPU instructions that only is simply not supported by the older physical processor.

  2. I can vMotion VM Cluster with older CPU for the Cluster with more recent CPU? Assume that CVS is not activated on the two groups.

  Yes, generally vMotion shall function in older generations of CPU to the most recent, the same common CPU instruction sets are supported by the destination CPU host and enabled in the BIOS.

  3. can I vMotion VM Cluster with older CPU for the Cluster with more recent CPU? Assume that CVS is not enabled on the source cluster, but active on the destination Cluster.

  4. I can vMotion VM Cluster with older CPU for the Cluster with more recent CPU? Suppose that EVC is enabled on the source cluster, but not active on the destination Cluster.

  Yes, the same general vMotion as explained above requirements. If CVS is enabled on any, both or a cluster does not matter (of course provided a configured VCA level is not reverse the physical hardware capabilities 'new' and 'old').

  5 can I vMotion of virtual machine of a stand-alone ESXi host on an active EVC cluster? Assume that the CPU is the same.

  Yes, the same general vMotion as explained above requirements. A stand-alone host is exactly the same thing treated as a non - active EVC cluster.
