VSphere EVC

[roelknippen]

Hi All,

I'am having a issue in configuring my home-lab whit VMWare EVC.

My Home-Lab looks like the following Hardware configuration:

2 Intel-NUC type NUC11PAHi7

1 Intel NUC type NUC12WSKi7

I am using the following software VErsions:

Vmware ESXi: Vmware ESXi 7.0.3

vCenter: VSphere Client version 7.03

U followed the following Guide: https://www.virten.net/2020/03/vmware-evc-mode-to-enable-intel-gen5-gen10-nuc-vmotion/

But when I try to set-cluster configuration I'am getting the following error:

Hope someone can help to get Vmware EVC working so VMotion between the NUCs can work. 

Thanks in advanced

@roelknippen,

By looking at your screenshot and at the product documentation, I can see that the ESXi have different CPU models and you have VMs powered-on on your cluster. 

The issue is that when you have VMs running on a newer CPU and you try to enable EVC you are downgrading the CPU features which is not supported to do it on hot. I assume one of those VMs is the vCenter as per the name so you cannot shut it down to change the EVC.

Do the following:

1. Remove the newer Intel NUC from vSphere

2. Enable EVC
3. Add the newer Intel NUC

That should do it.

Hi,

Thanks for the reply.

On the Intel Nuc of the type NUC11PAHi7 are running two VM's One off them is V-Center and the other is a domain controller which is serving as my DNS server.

I removed the intel NUC of the Type NUC12WSKi7 and powered down the Domain Controller. The V-Center server is still running because there i need to configure VMWare EVC. But when I do I still get the same error as above motioned in the screenshot. 

Is it possible to powerdown the V-Center server and configure VMWare EVC on the ESXI hosts?

Thanks for the Reply in advanced

@roelknippen,

Quick question, do you have Shared Storage between these ESXi?

hi,

I did the following to solve the issue. 

I created a new cluster with Vmware EVC enabled. 
Moved the ESXI host where the VCenter Server was Hosted. 
Added the other ESXI host to the knew cluster. 
Rebooted the vm's

And then everything started to work.
