ls -alh /sys/class/net/
...
ens160 -> ../../devices/pci0000:00/0000:00:15.0/0000:03:00.0/net/ens160
...

Than try to reboot VM. Network initialisation during boot will take much longer. Connectivity to VM via LAN will be broken. Open console to VM, check interfaces again:

ls -alh /sys/class/net/
...
lrwxrwxrwx 1 root root 0 Sep 22 12:12 eth0 -> ../../devices/pci0000:00/0000:00:15.0/0000:03:00.0/net/eth0
...

If we will remove configuration files created by bootstrap-aio.sh:

mv /etc/systemd/network/*osa* /root

and reboot VM, network connectivity will be restored. It looks like system network config is not compatible with installed by bootstrap-aio.sh into /etc/systemd/network

2. According to man 5 systemd.link there is no "Name" option in "Match" section

    Use OriginalName instead of Name in systemd.link

    Name option is not a valid one for systemd.link [1] while it is for systemd.network [2]
    though having same meaning.

    This basically resulted in link files being just ignored by udevadm
    and were not loaded properly after reboot
