• VCA mode in settings of the cluster

  I was wondering what an experience everyone was with the VCA mode settings.  Usually allow you it?  What mode for processors Intel you choose usually?

  the only time you need to activate the VCA is when you have vMotion compatibility issues.  And when allowing it, CVS will choose what mode is the best

• VCA Mode change

  Hello
  I'm downgrading to Westmere EVC mode to conform to the old generation of host we add to the cluster.

  To do this, I currently have two clusters created, in production and two hosts using sandybridge.

  the second group has a central server inside and westmere generation.

  I am aware of the procedure found here:VMware KB: VCA allowing on a cluster when vCenter Server is running in a virtual machine

  My question is, rather than quick vMotioning of all hosts another machines.  is it possible to close all virtual machines on a host, set mode now, disconnect the host, move it to the cluster Westmere allow it and then put on all virtual machines?

  I know that I'll still have to disconnect and reconnect my vcenter server, but I would like to avoid having a large amount of machines to vmotion if I can find some downtime to stop all.  and make them move with the host.

  This idea is possible?

  So if I understand what you really want is the future VMs with the host computer, then when you add the host to the new cluster and power them they will run under the new EVC Mode but you essentially in bulk installs what you wanted?

  If so, I did what you describe a bunch of times before (especially during migration between vCenters and want to go to the host and all virtual machines), what I would recommend however keeps the VMs powered on. Disconnect the host and then remove the vcenter. Once removed from the cluster and vCenter connect through thick client and put all virtual machines. Then add it to vCenter, in the cluster you want to and feed the VMS and you would be actually resigned these VMs in bulk.

  Conversely, you can turn off the virtual machines and keep track of those you want to migrate, put the host in maintenance mode and move it to the cluster that you want and then get out of maintenance mode, cold migrates virtual machines and then turn on. I think that this option will be a little easier.

  However, to disconnect a host and removing vcenter will make virtual machines with it, that looks like what you want to do...

• VCA mode disabled / vmotion work?

  We have 2 groups of ESXi at our facility for vSphere, vSphere is version build 5.5U1, currently most recent available.

  Group 1 has Intel Xeon E7540 UC.

  Group 2 is brand new and uses recently published processors Intel Xeon E7-4860 v2.

  VCA is currently disabled on the two groups.

  Athe's systems are listed in the VMware compatibility guide for our latest version of vSphere.

  I expect this Setup to be able to live vMotion of virtual machines from the old to the new cluster without the use of CVS on either, but I assumed that the migration back to group 1 would require cluster 2 to affect the level of reference Intel EVC appropriate (Nehalem in this case).

  It turns out that I am able to migrate VM direct in both directions with no apparent problems (so far), with EVC mode disabled on both groups.

  Is an expected behavior or if ESXi/vCenter is somehow misreading? CPU compatibility (perhaps because the E7-4860v2 are a very recent model) or some other issue that could lead to problems with these migrations?

  This is normal unless you have turned to bike the VM on the new hosts.

  If a virtual machine has been powered - on on a former host and is migrated to the new cluster, it does not change the current features of the virtual machine CPU runlevel. He will continue to work with the old CPU features on the new host and is therefore able to migrate the old new host without problems, or additional AIDS such as CVS.

  However, if stop you now migrated virtual machine and power it on again on new hosts, the virtual material will apply the new host CPU capabilities (or the level of EVC of cluster, but you do not apply any) and you will not be able to migrate the computer virtual return to the armies of the former cluster.

• Activation of VCA mode for cluster production

  Hello

  I have the following configuration:

  • Existing Cluster_A with ESX 3 hosts running on the processor Intel Xeon E5540 (Nahelem)
  • 30 VM runs in a production environment
  • 2 new ESX hosts running on the processor Intel Xeon E5649 (Westmere)

  2 new guests are not added in vCenter again, but the goal is to allow the addition of these 2 new hosts in Cluster_A.

  I understand that, in order to have all 5 hosts in the same cluster, EVC mode must be activated with the highest level being "Nahelem" (lowest common denominator).

  From a theoretical point of view, masking any CPU to apply will be identical to the current CPU presented the virtual running machines, settings allowing CVS using the same architecture CPU should not cause conflict or problem.

  Therefore, I would ask you confimation that activation VCA and Nahelem for Cluster_A upgrade will not cause downtime or impact (e.g. BSOD) to the virtual machines.

  Thank you

  Hello

  Is 100% safe operation (done many, many times the performance of clusters). No side effects :-)

  1. create a TEST VM
  2. Add the new server ESX to vCenter
  3. put in maintenace mode
  4. Add to the cluster
  5. allow to LCA
  6. exit maintenance ESX
  7. try to vMotion between the old and the new node in a cluster
  8. If vMotion won't work, says André, you should turn off the virtual machine and run it.
  See you soon

• Problems with the VCA mode when moving to Vcentre 4.1

  Hi all

  I currently have three ESXi 4.0 update 3 host running in a cluster. Two servers are identical and the third a later generation of CPU. The cluster is running in mode VCA Intel i7 with success.

  Also, my server Vcentre is 4.0 update 3 running on a 32-bit Windows Server 2003 R2.

  I built a new server on Windows Server 2008 R2 Vcentre and I am running Vcentre 4.1 update 1.

  I did the exercise to my old server Vcentre guests to my new. No problem until I try and their cluster. My server with the latest CPU is not allowed admission to the cluster. The new cluster is running same EVC mode as the old cluster.

  Need to update 4.1 Vcentre 1 be backward compatible for EVC modes with respect to the material?

  The servers are all DELL R710, the old two servers running XEON X 5570 processors and the latest Intel XEON X 5670 processors host tracks

  Do I have to update all 3 hosts 4.1 before I can redefine the clusters in EVC mode?

  Hoping that someone has been through a similar experience and can advise you. Unfortunately, I do not have a test lab to run it on.

  See you soon. Mark

  I don' t think you need to upgrade to ESX host.

  I think try in the following order:

  (1) turn on VCA for cluster

  (2) add the latest processor, select baseline and then old processor server.

• VCA mode - vm vmotion level lower than the level when turned on?

  Hi all, trying to get a definitive answer on this one there...

  Assuming that ESXi 5.1 u2, if you have two clusters, a set to VCA = Westmere and a game to Haswell, could you vmotion a powered on virtual machine cluster (Westmere) at a lower level to the upper level (Haswell) cluster, or must it be turned off?  I realize that, to take advantage of the latest processor have together, the virtual machine power cycle is required, but I didn't understand if you can vmotion it when turned on?

  Thank you! ~

  Yes, you can vMotion as a virtual computer to a host of generation more recent CPU very well provided that it contains of identical CPU instructions sets that older CPU's (the host has them enabled in BIOS too). You can vMotion that their return to guests because as long as you do not have virtual machines powered bike, they will continue to work with the old base EVC.

• Activate the VCA Mode of VMware vCenter Server Appliance

  Hello

  I'm pretty new on vSphere.  I have two hosts running esxi 5.1 what one of these hosts running the "VMware vCenter Server Appliance' with vSphere version 5.5.  I currently have a single cluster containing all the VMS as well hosts and the SAN.

  I try to activate the EVC mode, but when I try it tells me that the host is not allowed because there are powered on virtual machines.  I can turn off all the virtual machines except the vCenter device and I still get the problem on the host that has the device on it.  If I turn off the unit, I can't use vSphere to activate CVS.

  How can I activate CVS when vSphere does not work?

  Thank you

  Jeff

  Hi Welcome to the communities,

  This one is a bit complicated

  You have:

  1. turn off all VMs on Host1 (while vCenter device is on Host2)

  2 bring Host1 on Cluster, select CVS clustered.

  3. put all the virtual machines on Host2 (also vCenter device)

  4. connect on Host2 directly to vSphere Client Windows

  5. remove the vCenter inventory unit

  6. connect on Host1 directly to vSphere Client Windows

  7. the data store when the appliance and add it to the inventory of research. Power on

  8. connect the device with Web client or vSphere vCenter

  9. move the second host in the cluster

  And you're done

• VCA Mode affect the Performance?

  I enabled on my AMD based blade Cluster.  Once I did, but I had a few complaints today claiming a general slowness on their desktop from view.

  These are older blades but now run our test environment seen for quite awhile without complaints.  Today, I added a more recent blade but was to turn VCA AMD Opteron Gen 2.

  3 blades are AMD Opteron 8218 and my 4th I've added today's Opteron 8356...

• VCA serious question in a cluster after adding servers active DRS blades M630 Dell

  Hi guys,.

  I hope that you will be able to help me with this strange question that I feel right now.

  A couple of details first on our environment:

  • vCenter 5.0 U3
  • ESXi 5.0.0 - 2509828
  • 6 guests active DRS cluster
  • 4 hosts are Dell M620, E5-26XX v2 processor blades
  • 2 hosts are blades M630 Dell with processors of E5-26XX v2
  • VCA mode is currently set at "Westmere".
  • All ESXi hosts are fully patched using AUVS

  Before adding the new M630 blades to the cluster it any of the issues with the DRS or VCA, outside the constraints of resources, and the 4 blades M620 we are able to correctly migrate the virtual machines back.

  I could add the M630 blades to the cluster without problem and without errors or warnings have been issued. A week or so later, I noticed more deviations of DRS desired on the cluster. More inspection I noticed that quite a large number of virtual machines showed N/A beside VCA mode and I was not able to migrate them to any host on the cluster.

  Thinking it could be a bug of sorts, I turned off all the virtual machines in the cluster and run a script that resets the CPUID at default. In addition, as a measure of precaution, I restarted the vCenter server and ensures that the database has been effective. The hosts are synchronized time with an NTP source and fits perfectly on both hosts.

  After feeding all the VMS, I rebooted the M630 servers and inspected the BIOS settings to ensure that virtualization and NX/XD is enabled. With all virtual machines powered off, I was able to change the levels of the VCA to any available without warnings setting.

  When everything has been turned back on I noticed a strange behavior in the cluster.

  Virtual machines that are running on M620 blades show the right level of CVS and I am able to migrate them to all servers in the cluster. Once that they migrate to the blades M630, VCA state change s/o and I am unable to migrate anywhere, not even the other M630 blade in the cluster.

  The error that I am shown during the verification step is:

  The operation is not allowed in the current state of the connection to the host. Host CPU is not compatible with the requirements of the virtual machine to cpuid level 0 x 1 host bit ' ecx' register: 0000:0010:1001:1000:0010:0010:0000:0011 required: x 110: x01x:11 x 1: 1xx0:xx11:xx1x:xxxx:xx11 inconsistency detected for these characteristics: * General incompatibilities; see section 1993 of possible solutions.

  Dig deeper in my investigation, I came across this KB: 1034926[1]

  I checked the M620 user guides and the M630 and parameters mentioned in the KB should be enabled by default. Unfortunately, I have no way to check the BIOS settings because I can not all M630 blades enter into maintenance mode without turning off the virtual machines running on them and another maintenance window one day after previous, we're going to be deprecated. In addition, the error is not the same as that of the KB and my goal is to collect as much information before entering another window of maintenance requiring downtime.

  I hope that you will be able to provide any new perspectives or opening my eyes to things that I may have missed.

  Thanks in advance.

  The processor in this system is a v3 E5-2660, not an E5-26xx v2.  ESXi 5.0 doesn't know how to use the features of this processor FlexMigration.  I think that the first version of ESXi to support this processor is ESXi 5.1U2.

  Unfortunately, I do not see a workaround for ESXi 5.0 solution.

• Do I have to downgrade CVS mode?

  Hello
  I want to add an additional host to my VMWare environment, which is running on version 5.5.

  Currently I have two hosts who are using Sandy Bridge.  The third host that I am looking to add would be a generation old, Westmere.  I checked the documentation and it also claims that it is a supported mode on the server itself under the "assumption of the EVC Modes"

  My question is that if I want to be able to perform a vmotion.  Will it switch the cluster "Westmere" VCA mode and if necessary, which is a procedure to follow to do.  For example, guests must be in maintenance mode, I have to turn off the virtual machines before making the change.  or that it will be possible to make a warm change so to speak?

  Once again, if you still do?

  You must shut down all virtual machines, see the documentation of procedures: Activate CVS on a Cluster in the Web Client vSphere

  And if your vCenter is a virtual machine, see this KB article: VMware KB: VCA allowing on a cluster when vCenter Server is running in a virtual machine

• Sanity Check: Hardware compatibility: vMotion/CPU/VCA etc.

  Hi all

  We currently have a DRS cluster with 6 hosts Dell Poweredge R610 with Intel Xeon 5540 or 5530 processors which, according to article KB (http://kb.vmware.com/kb/1991) are in Group D for the vMotion compatibility. (Nehalem-EP)

  I want to add new hosts to the cluster and try again Dell R620s. These have Xeon CPU E5-2640. I can't find an article with the same level of detail for the new processors. The compatibility guide Vmware tells me that it is a Sandy bridge processor?

  
  

  If I add hosts with newer processors to the cluster, be they work? Or do I have to turn on some sort of CVS mode?

  
  

  If I read this article (KB VMware: best vMotion compatibility (EVC) processor support ) he gives to think that I would need to market the VCA Level2 (Nehalem). This would be 'disable' have the CPU features in the new host beyond what former processors... But what happens in 'x' time of years when all guests have disappeared - presumbaly I can then disable compatibility EVC mode so that all the features of the CPU are presented? This would have a negative impact on existing virtual machines?

  
  

  Please could someone health mental check me or point me in the direction of something to reassure me?

  
  

  Thanks in advance
  

  
  

  
  

  
  

  NB. Currently on vSphere 4.0, but the upgrade to 5/5.1 soon.

  
  

  
  

  I suppose that once the VCA mode is activated, it will always be equal to the level of the 'down' (older?) (In this case Nehalem) CPU level up to what the last host with Nehalem processors is removed from the cluster.

  Yes, that's correct.
