Meaning the bisection result:
167dcfc08b0b ("x86/mm: Increase pgt_buf size for 5-level page tables")
is bogus?

Dmitry,
Can you share the host kernel version?
I can not reproduce any of these crash signatures and I think it's
really a nested virtualization bug. So I will need the exact host
kernel version as well.
I am currently getting all sorts of:
"KVM: entry failed, hardware error 0x7"
... instead
Looking also at the other crash [0]:
