Created attachment 777866 [details] A XML describing a CPU to be compared with the host. Description of problem: The virsh cpu-compare does not report my POWER7 rev 2.1 cpu as compatible with itself. Version-Release number of selected component (if applicable): 1.1.0 How reproducible: 100% Steps to Reproduce: 1. Run virsh cpu-compare description.xml on a POWER 7 2.1 host(this file is attached) 2. The host CPU is reported as incompatible with the CPU described in the XML Actual results: The CPU is reported as incompatible. Expected results: The CPU should be reported as identical to the host CPU. Additional info: The "ppcModelFindPVR" function in the cpu_powerpc.c source file uses a direct comparison (equality operator) between the host CPU PVR code and the PVR code described in the cpu_map.xml for the POWER7 processors. This comparison should ignore part of the PVR code that indicates the revision of the processor, as described in the POWER ISA, page 745: https://www.power.org/wp-content/uploads/2012/07/PowerISA_V2.06B_V2_PUBLIC.pdf
