Hmmm. How is tpr patching works then? It relies on ability of a guest to
write into BIOS memory region. Need to retest if it actually works I
guess.
The last time I looked, the TPR patching backend forced the "vapic"
pages to be writable (effectively overriding the bios decision to make
it readonly).
Does the TPR thing have to live in the optionrom/bios space or can it be moved
somewhere else like just below 4GB (some other kvm stuff is already there) ?
