Hi All,
I am not sure about the update strategy of CPU models in libvirt.
IMO, It's depend on the CPU model in qemu-kvm, if some CPU models
were updated in qemu-kvm. Then, we should modify the src/cpu/cpu_map.xml
of libvirt to synchronize?
eg:
commit cad8054ece28("cpu: Add cpu definition for Intel Sandy Bridge
cpu type") in libvirt upstream.
https://bugzilla.redhat.com/show_bug.cgi?id=761005
If it's right, I found this commit b3a4f0b1a072("target-i386: add VME to
all CPUs") updated the VME feature in qemu upstream. But in the src/cpu
/cpu_map.xml of libvirt, It didn't be updated.
eg:
For the SandyBridge CPU,
- In QEmu, it has the 'vme' feature defined by CPUID_VME
- In libvirt, it doesn't has the 'vme' in cpu_map.xml file.
Why?
Thanks,
dou
