--- Comment #29 from muncrief (rmuncrief@humanavance.com) ---
I have to knock off for today gentlemen, but just wanted to let you know that
if I disable nested virtualization in the host-passthrough configuration I get
the same avic_inhibit_reasons value as the EPYC-IBPB configuration. So instead
of "20 28" for host-passthrough I get the same "16 24" as EPYC.
I also saw Anthony's comment about synic so I turned it off in both
configurations with "<synic state='off'/>", but it didn't affect anything on my
system. I think it's actually off by default though because when I tried to
turn it on with "<synic state='on'/>" I got an error when trying to save the
XML.
