yes i used that tool to downgrade libvirt to 7.9.0 from 7.10.0 as that was the only local version i had to downgrade to. it didnt fix it. its a qemu issue i guess. i went back to kernel 5.14 and that fixed it. will wait for that fix to land to fix it before going back to 5.15.
i updated the thread title to reflect the new info.
