Re: [libvirt PATCH 5/9] tools: Report hypervisor cpu model names

$ virsh hypervisor-cpu-models --arch x86_64 Name Alias ---------------------------------------------------- max host base qemu64-v1 qemu64 qemu64-v1 qemu32-v1 qemu32 qemu32-v1 phenom-v1 phenom phenom-v1 (...) Note that this includes alias names and cpu models that currently do not exist in libvirt, e.g. Denverton and Knights Mill.
