[SOLVED] Help about cpu type

[crc-error-79]

Hello, I have a proxmox server with a Xeon E3-1265L v3 (link intel ark) and another machine with a Xeon E3-1240 v6 (link intel ark), how can I choose the right cpu type?
I checked on the documentation but the page with the list is not available..

Use host for max performance, but only if you have a singlehost. If you have a cluster, make sure all hosts have same cpu, otherwise livemigration might not work.

Sorry I forgot to mention that I don't want to use host but keep the processor inside of machine "generic", but with the right features.

Both my cpu supports AES so the default x86-64v2 AES should be ok, but maybe I can set the v3 or the v4.. but how can I check if the instructions of the v3 and v4 are supported by the xeons I have?

if the nodes are in a cluster, you need a CPU type both hosts support for live migration. Otherwise you can just select the most fitting model from the list.

I checked on the documentation but the page with the list is not available..

The wiki page is auto-generated from the documentation and it seems something went wrong with the link during conversion. The list is available here: https://pve.proxmox.com/pve-docs/pve-admin-guide.html#chapter_qm_vcpu_list

You need >=Broadwell for x86-64-v3 and >=Skylake for x86-64-v4, so I think your Haswell CPU is too old for either of them. QEMU should also tell you that features are not supported by the host CPU and refuse to start if you select and incompatible CPU model.
