Thank you Paolo, but I have another question. I was wondering if it is
appropriate to enable X86_FEATURE_WAITPKG when QEMU uses "-overcommit
cpu-pm=on"?

"-overcommit" only establishes the behavior of KVM, it doesn't change
the cpuid bits.  So you'd need "-cpu" as well.

OK I got it. Thank you for your review.
