Directly assigned as a result of owning RHEL9 bug. I did not reset target release to 8.5 as I'm not sure that will be possible. It's an engineering decision in the long run, but would involve trying to apply more recent upstream changes to an older qemu since RHEL 8.5 was based on qemu-4.2, while RHEL 8.6 and beyond will be based on qemu-6.2. Cloning this bug to resolve a RHEL-AV bug is technically possible, but not preferred. David Gilbert created an issue for implementing this at Libvirt gitlab repo: https://gitlab.com/libvirt/libvirt/-/issues/306 I am not sure if someone is already working on that, but I could see no merge request nor master commit related to that. So, I am currently trying to understand how to add that in libvirt, but honestly I am very new to the code, and I am still not sure how it should be done. Hi leonardo, Thanks for the update of DTM and ITM. Just a reminder here that DTM 18 is July 4, can we get the available qemu-kvm downstream before that? Since QE also needs at least one week to test this future feature. I would suggest move ITR from 8.7.0 to 8.8.0 if we still can't make the qemu-kvm available in downstream before DTM 18/19. Thanks for the understand! Fix included in qemu-kvm-6.2.0-17.el8 Fixed by merge request 'MSG_ZEROCOPY + Multifd @ rhel8.7' ( https://gitlab.com/redhat/rhel/src/qemu-kvm/qemu-kvm/-/merge_requests/191 ) Hi Camilla, Why don't we have "qemu-kvm-6.2.0-17.el8" in "Fixed In Version" Move ITM from 20 to 21 for fully tests about zerocopy. QE bot(pre verify): Set 'Verified:Tested,SanityOnly' as gating/tier1 test pass. Verify this bug on qemu-kvm-6.2.0-18.module+el8.7.0+15999+d24f860e.x86_64, same test results as https://bugzilla.redhat.com/show_bug.cgi?id=1968509#c23 I have cloned one bug for RHEL 8.7.0: Bug 2110203 - zerocopy capability can be enabled when set migrate capabilities with multifd and compress/xbzrle together For dst qemu crash issue under postcopy + multifd scenario, I will wait for Leonardo's reply to decide to whether need to clone: https://bugzilla.redhat.com/show_bug.cgi?id=2106726#c1 Mark this bug as verified per above test results. I would add test cases in migration test plan later, so remove the "SanityOnly" from Verified firstly. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
