qemu-kvm-7.1.0-5.el9.x86_64
kernel-5.14.0-200.el9.x86_64
seabios-bin-1.16.0-4.el9.noarch

100%

Steps to Reproduce:

2. install vioser driver and do migration directly
3. uninstall driver and reboot/shutdown VM.

Actual results:
VM hang and the screen is black.

Expected results:
VM shutdown/reboot successfully.

Additional info:
the background is we add memory_leak_check for all cases that include enable verifier driver operations, since the uninstall driver operation is included memory_leak_check function and executed after all function test steps. so this scenario is new for this migration case.
