Greeting,
FYI, we noticed the following commit (built with gcc-9):
commit: feb627e8d6f69c9a319fe279710959efb3eba873 ("KVM: x86: Forbid KVM_SET_CPUID{,2} after KVM_RUN")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master

Hm, I'm pretty sure I've tested feb627e8d6f6 on both Intel and AMD and I
don't remember seeing this failure :-( . vmx_pmu_msrs_test test does
KVM_SET_CPUID after KVM_RUN and thus needs to be fixed too. Will send a
patch shortly.
