[pve-devel] PVE 4 and CPU errors

[Cesar Peschiera]

Hi Alexandre

Since much time ago, i did want to have a list of processor names (as
Nehalem, Sandy bridge, Haswell etc.) and his respective models (X7560,
etc.).

Is there a web link internet with this information?, or
Can you or anyone add this information in the wiki of PVE?

I think that such information will be very util for choose the better
processor when we create a VM and we want enable live migration with old and
differents processors and not die in the intent.

Best regards
Cesar
