I checked that: - After upgrading QEMU from 5.2.0 to 6.0.0-19, I can reproduce the bug. - After further upgrading QEMU from 6.0.0-19 to 6.0.0-21, the bug disappears (thanks to Jean-Louis for pointing out the corresponding bug in Comment 3). Since AV 8.4 has QEMU 5.2 and the upcoming AV 8.5 has a fixed QEMU version now, I think we can close this bug, it concerns only an interim QEMU version that nobody is going to use in future. Nathaniel, could you check whether updating QEMU to 15:6.0.0-21 fixes the problem for you too, once it is available in Stream?

Ah, right, ovirt-node 4.4.7 has the broken QEMU version :-(. Sandro, any chance to get an updated version in Node?

Can somebody please test this build ?: https://jenkins.ovirt.org/job/ovirt-node-ng-image_master_build-artifacts-el8-x86_64/784/artifact/exported-artifacts/ovirt-node-ng-installer-4.4.7-2021071221.el8.iso It's a custom build with qemu-img/kvm*/guest-agent 5.2.0. There is also a corresponding update package at: https://jenkins.ovirt.org/job/ovirt-node-ng-image_master_build-artifacts-el8-x86_64/784/artifact/exported-artifacts/ovirt-node-ng-image-update-4.4.7.1-1.el8.noarch.rpm Please note that these ISO and RPM also contains a fix for the https://bugzilla.redhat.com/show_bug.cgi?id=1979624 Tested with the RPM, and it seems to work fine! Tested it with the iso, and can confirm that it's working fine for receiving migrations. Eduardo, can you provide a new qemu-kvm build with the fix?
