How to make VMotion works among different CPU cores

[vmk2014]

HI,

  We have 5 Host in a cluster but host are of  different  CPU models and  cores.I want to make VMotion works across all hosts. Thanks

Host	CPU Model	Speed	Cores per CPU	Current EVC	Max EVC	ESX Version	Vendor	Model
ESXi005	Intel(R) Xeon(R) CPU           E5620  @ 2.40GHz	2,393	4		intel-westmere	VMware ESXi 5.1.0 build-1117900	Dell Inc.	PowerEdge R710
ESXi006	Intel(R) Xeon(R) CPU           E5620  @ 2.40GHz	2,393	4		intel-westmere	VMware ESXi 5.1.0 build-1117900	Dell Inc.	PowerEdge R710
ESXi007	Intel(R) Xeon(R) CPU           E5620  @ 2.40GHz	2,393	4		intel-westmere	VMware ESXi 5.5.0 build-1746018	Dell Inc.	PowerEdge R710
ESXi008	Intel(R) Xeon(R) CPU E5-2660 0 @ 2.20GHz	2,199	8		intel-sandybridge	VMware ESXi 5.1.0 build-1117900	Dell Inc.	PowerEdge R620
ESXi010	Intel(R) Xeon(R) CPU E5-2670 v2 @ 2.50GHz	2,499	10		intel-ivybridge	VMware ESXi 5.5.0 build-1746018	Dell Inc.	PowerEdge R620

Hi

create EVC cluster...

Look for example here: http://buildvirtual.net/vsphere-5-configuring-evc

and or here: http://www.virtualizemydc.ca/2013/10/25/vmotion-virtual-machines-between-clusters-with-different-hos...

Hello vmk2014,

If you want the flexibility to mix clusters/migrate VMs between hosts of different CPU generations, activate EVC using the lowest common denominator, which is Westmere in this case. While enabling EVC, you need to power off all the VM's and keep the host in maintenance mode.

Hi,

Thanks to all.I saw the links. Just to confirm Still i need to shutdown the VM's if i create new empty Cluster and enable EVC mode and then VMotion the VM's ? Thanks

thanks

Hi,

When you create a EVC cluster, You will not able to add any host to it with a power on VM. What you need to do is, Power off all the VM's add host to EVC cluster and power on vms back. you need to do this with all the hosts which you want to add to EVC cluser. Please read this link it will be helpful

Hi,

yes it is needed to shutdown the VMs before they get loaded with new set of CPU masks on boot-time for your given Enhanced vMotion state.
