What were you trying to do that didn't work?

Use an autostarted VM after the Leapp upgrade.

Please provide the package NVR for which bug is seen:

libvirt-8.0.0-23.module+el8.10.0+21023+5962ee04
leapp-upgrade-el8toel9-0.19.0-9.el8

How reproducible:

100%

Steps to reproduce

1. On a recent 8.10 installation, create a VM with an pci hostdev and attached to the default NAT network
2. Mark the VM as autostart, reboot host and confirm it's autostarted
3. Run the leapp upgrade

Expected results

After the final reboot, when I log in the VM is running

Actual results

The VM is not running. The log complains about connection issues with virtnetworkd-sock which is weird because 8.10 has the monolithic libvirtd daemon and should run also libvirtd monolithically on the target 9.4.

After starting the virtnetworkd manually the VM can start.

Additional info:

1. it was found when upgrading 8.10->9.4; it reproduces when upgrading 8.10 -> 9.3 with libvirt-9.5.0-7.el9_3.s390x
2. it doesn't reproduce when upgrading 8.9 -> 9.3

3. # systemctl status virtnetworkd
