Starting with the edk2-stable202508 tag OVMF (and ArmVirt too) have
optional support for logging to a memory buffer. There is guest side

But that might not helpful if your guest stops booting early enough that
guest tooling can not be used yet. So host side support to read that
log buffer is a useful thing to have.
This patch implements both qmp and hmp monitor commands to read the
firmware log.

At a glance, why not "info ovmf-log" and "query-ovmf-log"?
