[libvirt-users] CPU model and type
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.
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> ...
