*** Bug 2021976 has been marked as a duplicate of this bug. *** Adding RHEL bug 1981782 as a depends on since that's RHEL 8.6.0 bug from which we cloned to RHEL-AV bug 2024981 so that we could create the proper z-stream bug. Can we get the qa_ack+ please, so that this can get release+? QE bot(pre verify): Set 'Verified:Tested,SanityOnly' as gating/tier1 test pass. Verified with qemu-kvm-6.0.0-33.module+el8.5.0+13514+2c386966.1.x86_64: The post copy live migration with vhost-user 1Q/2Q/4Q all work well. No any issues found.
