## Observation

This is possibly a regression from libvirt update 8.9->8.10

the test launches a nested VM using
virt-install --memory=512 --name=nested_vm_test --graphics=vnc --disk=none
--boot=cdrom)

After that, the test issues a "virsh list --all" and expects that
nested_vm_test to show up there

openQA test in scenario
opensuse-Tumbleweed-DVD-x86_64-upgrade_Leap_15.2_with_service_check@64bit fails
in
[nested_vm](https://openqa.opensuse.org/tests/2937999/modules/nested_vm/steps/36)

## Test suite description
Maintainer: wegao@suse.com 
Upgrade test Leap 15.2 to TW with service check
Currently ONLY exist libvirt service check, if more service needed we can added
into it.

Extra setting:
NESTED_VM_DOWN=1 will shutdown nested vm before migraiton


## Reproducible

Fails since (at least) Build
[20221207](https://openqa.opensuse.org/tests/2936174)


## Expected result

Last good: [20221206](https://openqa.opensuse.org/tests/2934162) (or more
recent)
