[kvm-unit-tests PATCH 3/3] x86/msr: Add an "msr64" test configuration to validate negative cases

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add "msr64" to run the MSR test with a CPU model of "qemu64" instead of
"max" to provide coverage for MSRs that exist in the underlying hardware,
but not in the guest's CPU model.
