Why only pKVM? Why only the host? Dumping page tables shouldn't be
reserved to this corner case. Specially considering that pKVM is still
really far away from being remotely useful upstream.
I'd really expect this sort of debugging information to be fully
available for both host and guest, for all modes (nVHE, VHE, hVHE,
protected, nested), without limitations other than the configuration
option.
Also, please Cc the relevant parties (I'm the only one Cc'd on the KVM
side...)
Thanks,
M.
