For positive cases, a check for warning or error in logs will help to detect the bug like https://issues.redhat.com/browse/RHEL-80533 . These virtualization related logs will be checked:
- libvirt daemon logs
- qemu domain logs: /var/log/libvirt/qemu/.log
- dmesg:
dmesg --level=err,warn,crit,alert,emerg --since <time>
