Re: [libvirt-users] CPU model and type
you can set the CPU type and model and features
https://libvirt.org/formatdomain.html
I usually give it during the virt-install as -cpu core2duo,+vmx (the
,+vmx will enable vmx vt extensions on the guest CPU )
...
<cpu match='exact'>
<model fallback='allow'>core2duo</model>
<vendor>Intel</vendor>
<topology sockets='1' cores='2' threads='1'/>
<feature policy='disable' name='lahf_lm'/>
</cpu>
...

Hello,
Is there a way to configure the domain cpu in such a way that the info
reported to the guest OS system will remain constant ? For example in older
versions of of libvirt/qemu the cpu was reported as "QEMU Virtual CPU
version (cpu64_rhel6)" but moving the vm on a qemu2.2.0 is is reported as
"QEMU Virtual CPU version 2.2.0".
Thanks.
