[libvirt] [PATCH v3 25/28] cputest: Test virQEMUCapsInitCPUModel

Jiri Denemark jdenemar at redhat.com
Thu Feb 23 14:15:23 UTC 2017 

The original test didn't use family/model numbers to make better
decisions about the CPU model and thus mis-detected the model in the two
cases which are modified in this commit. The detected CPU models now
match those obtained from raw CPUID data.

Notes:
    Version 3:
    - no change
    
    Version 2:
    - updated test results to include vendors
