AFAICT, KVM has been very much broken on these sytems for a while.

We still have an OPAL POWER7 system running a debian11 in the labs
if you want to check. But, honestly, I wouldn't worry too much about
it. POWER8 and above should be the focus. Anything below: POWER7,
POWER5+, 970 work well enough under TCG.
