The new command can be used to generate test data for virCPUUpdateLive.
When "cpu-cpuid.py diff x86-cpuid-Something.json" is run, it reads raw
CPUID data stored in x86-cpuid-Something.xml and CPUID data from QEMU
stored in x86-cpuid-Something.json to produce two more CPUID files:
x86-cpuid-Something-enabled.xml and x86-cpuid-Something-disabled.xml.
- x86-cpuid-Something-enabled.xml will contain CPUID bits present in
x86-cpuid-Something.json (i.e., enabled by QEMU for the "host" CPU)
- x86-cpuid-Something-disabled.xml will contain all CPUID bits from
x86-cpuid-Something.xml which are not present in
x86-cpuid-Something.json (i.e., CPUID bits which the host CPU
supports, but QEMU does not enable them for the "host" CPU)
