Re: [libvirt] [PATCH 09/23] cpu_x86: Disable blockers from unusable CPU models

When decoding CPUID data to virCPUDef we need to be careful about using a CPU model which cannot be directly used on the current host. Normally, libvirt would notice the features which prevent the model from being usable and it would disable them in the computed virCPUDef, but this won't work in case the definition of the CPU model in QEMU contains more features than what we have in cpu_map.xml. We need to count with the usability blockers we got from QEMU and explicitly disable all of them to make the computed virCPUDef usable. https://bugzilla.redhat.com/show_bug.cgi?id=1464832 Signed-off-by: Jiri Denemark <jdenemar(a)redhat.com&gt; --- src/cpu/cpu_x86.c | 23 ++++++++++++++++++++--- 1 file changed, 20 insertions(+), 3 deletions(-)
