Reviewed-by: Roman Bolshakov <rbolsha...@ddn.com> Hi Phil, I don't observe any change in x2apic KVM unit tests with the patch. I tried the single patch and the series, not looked into the test failure yet. Do you happen to know why? Also what guest do you run? Desktop Ubuntu 24.04 doesn't seem to work with x86 HVF. Thanks, Roman
