Welcome to the Community,

possible EVC modes depend on the ESXi hosts' processor, and any already powered on (or suspended) VMs.

The EVC mode has to be lower, or equal to the hardware's capabilities, but the same, or higher as already running VMs.

If you cannot figure out what to use, please provide details about the ESXi hosts, i.e. their CPUs.

But i choose all option and again not possible.and all my vm is on power on status

Please answer the following questions:

• what's the  vCenter Server version and build?
• what's the ESXi host version and build?
• what server hardware do you use, i.e. which CPU models?

André

vcenter 6.7

esxi 6.7 updtate u3

hpe proliant 580 gen 9 and gen 10 cpu 8848 core 4

Hello Imran,

EVC cannot be enabled (or the host cannot be admitted into a EVC enabled cluster) on a cluster with VMs being in powered on status.

EVC Mode - Intel Merom Gen - Xeon E5345 - E5-2690 - The host cannot be admitted the cluster's curren...

i didnt understand i have to power off all my vms?

The screenshot that you've posted doesn't show the "Broadwell" and "Skylake" compatibility mode.

Which vCenter Server "Build" do you have installed? It may be worth updating to the latest build.

André

As per my understanding, yes you have to. EVC cannot be enabled on a cluster which has VMs in powered on state. Please check step-21 in the below KB -

no i  choose all options they all shows not compatibility with gen 10 server.other shows not compatibility both gen 9 and gen 10 server.but my server is critical i cant turn off.but i remember before i can migrate vm without cluster.just enable vmotion in between esxi 6 and 5.5 but after update i cant migrate

but also i triend enable evc and then when i tried to add second host to cluster i didnt do because i showed not compatibility ti add host cluster evc

you write you can migrate vm BEFORE enabling vmotion ? how?

btw: shutting down the vm and then check the evc-mode that is possible for your hardware is the only option you have. think about a downtime for your vm and then just do it.

the normal way is to deploy the cluster, check all functions and after that put productive vms on it, not deploy vms and check functionality afterwards.

the people here tried to help you - so please listen to them

Did you try any other CPU model like Penryn, Sandy Bridge etc,

Or provide vpxd.log for looking which vm is causing the issue, then you required only power off that vm.

i said i can migrate with vmotion without cluster in old version but now i cant turn off vms.because it is not allowable to turn off.

yes i tried all options and also amd processor and intel processor.please also help me how i can find log file

cd /var/log/vmware/vpxd/vpxd.log is it this?

cd /var/log/vmware/vpxd/vpxd.log this you mean?
