Hi,
Thanks for you reply.
As far as we are concerned, we have two clusters with perfectly identical CPUs,
respectively. Not the same family.
I understand that a cluster will only allow CPUs of the same "family" but I
never investigate that.
Is there a CPU family <--> CPU name relationship somewhere ?
That said, are those extra instructions only relevant to nested virtualization,
or can they provide real performances improvement ?

If you have hosts with the exact same cpu, you can enable cpu passthrough and set the hosts from
the "Specific Host(s)" section. Also you can set the migration mode to "Allow manual
and automatic migration".
I guess you already noticed that VMs with CPU passthrough have access to more
CPU instructions compared to the Virtualized one.

Hi,
What are the pro and cons of enabling pass-through CPU ?
It is a greyed option for a VM, unless specific host(s) is/are selected.
That's the thing : it's possible to select all hosts..., so, it does not make
difference w/ "Start on any host" option
