[Qemu-devel] [PATCH 1/1] x86: add CPU flags supported inside libvirt

[Denis V. Lunev]

There are the following flags available in libvirt inside cpu_map.xm
    <feature name='cvt16'>
      <cpuid function='0x80000001' ecx='0x00040000'/>
    </feature>
    <feature name='cmt'> <!-- cqm -->
      <cpuid eax_in='0x07' ecx_in='0x00' ebx='0x00001000'/>
    </feature>
We have faced the problem that QEMU does not start once these flags are
present in the domain.xml.

This patch just adds proper names into the map.
