TL;DR - I was able to confirm Markus test results - results LGTM (other than a few hickups probably due to my special HW) - a few questions to Markus (see below) - With these positive resilts I'd already go on and combine this with another SRU to prep merge proposals for F/G/H. - Once ready and reviewed it will depend on the timing how exactly we upload - and then - verify it again
@Markus - Just to be sure on these details let me ask A) - with EPYC-Milan / EPYC-Rome(-v2) types are for you the MSR errors gone on your Chips? - Or only when you manually add IBRS and/or other things? B) - since you have multiple EPYC chip types - when the time comes for this to become an SRU can I count on you to help test this again (in multiple releases)? C) in https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1921754/comments/7 you said you had these MSR errors on "5.4.0-70 on both host and guest" with 5.4.0-71-generic (current). I don't see them. And the fix isn't there yet as the kernel bug will only be resolved the next kernel update. Therefore - did you really see this with the guest on 5.4 or was this a mistake? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1921880 Title: Add EPYC-Milan model To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1921880/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
