[libvirt] libvirt-lxc broken by new systemd 243

Hi, with the new systemd 243 libvirt-lxc seems broken. We had the particular symptom already in the past, the TL;DR is: 1. start a lxc guest 2. restart libvirtd 3. guest is gone This particular change is due to [1] fixed by [2] which as a side effect will wipe libvirt-lxc containers on daemon restart. After checking on IRC it seems this wasn't reported to libvirt yet, but for now it is more a start of a discussion than a bug report. I have reported this upstream at [1] and we could keep the "discussion with systemd" there. If you can/want please chime in there. If it turns out we want/need a fix in libvirt we can focus on the thread here then.
