[pve-devel] [PATCH] Force CPU vendor

[Dietmar Maurer]

I applied a modified version, using a declarative vendor list:

https://git.proxmox.com/?p=qemu-server.git;a=commitdiff;h=8930da746fa44c154dacb978e3e4bbb94cdb688b

Please can you test? I also added 

+    coreduo => 'GenuineIntel',
+    core2duo => 'GenuineIntel',

which was missing in your patch. Hope that is correct?
