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 "", 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 "" I got an error when trying to save the XML. -- You are receiving this mail because: You are watching the assignee of the bug.
