ESXi 5.5 - vCenter 6 - EVC Haswell

[BenoitSponem]

Hi,

We have one cluster with:

- 5 ESXi 5.5u3 Dell R730 / R630 with E5-2687W v3 and E5-2697 v3 processors.

- vCenter 6 (build 3339084)

When i choose EVC on cluster with "Intel Haswell Generation", I get the following error for all hosts:

The host's CPU hardware should support the cluster's current Enhanced vMotion Compatibility mode, but some of the necessary CPU features are missing from the host. 

Check the host's BIOS configuration to ensure that no necessary features are disabled (such as XD, VT, AES, or PCLMULQDQ for Intel, or NX for AMD). For more information, see KB articles 1003212 and 1034926.

In Bios i have this settings:

Which settings I missed?

Thank you

The BIOS configuration are the same in all hosts ? If you lower the EVC level to Ivy Bridge it works ? Without EVC, try migrate a virtual machine from one R730 to R630 (and vice-versa) and take note about what features are incompatible and this will give us a clue about what feature we should look at BIOS. And your BIOS are updated ?

This isn't a problem in your BIOS this is in vSphere.  You need to play with the generation settings, even try lowering a level.

Now, EVS is disabled and i can migrate VM between all hosts without error.

Bios are in lastest version from dell (1.5.4).

I can't activate Ivy Bridge Generation because VMs are already powered on so i have this message:

The host cannot be admitted to the cluster's current Enhanced vMotion Compatibility mode. Powered-on or suspended virtual machines on the host may be using CPU features hidden by that mode.

Unfortunately, i cannot choose lower level than "Haswell" because there are already powered on VMs  (> 150).

You need to play with the generation settings

How can i set these settings?

I am having an issue that is almost identical to this. Did you find a solution?

Sounds like Haswell is only supported if the vCenter and Hosts are at 6.0

I assume all hosts in the cluster have same processors since you can vmotion VMs across hosts. In this case, do we really need to enable EVC?
