Problems with modular libvirt daemons

[dutrajulio]

The newly adopted modular libvirt daemons on RHEL 9, and derivatives, appears to cause problems with external resource dependencies (systemd drop-in units).

In my test environment, the drop-ins "99-VirtualDomain-libvirt.conf" and "99-VirtualDomain-machines.conf" seems to be ignored. When reboot/shutdown a node the virtual domain migration fails and the node is fenced.

But if i manualy start the "libvirtd.service" before reboot/shutdown the node, then the process works correct.

Configure a drop-in unit for "virtqemud" works exactly like "99-VirtualDomain-libvirt.conf" do for "libvirtd".

Thanks. I'll look into it.

Someone pointed me at this code: https://github.com/ClusterLabs/resource-agents/blob/main/heartbeat/VirtualDomain#L676-L680

Where After: libvirtd.service you probably want to copy the virt related After: lines from libvirt-guests.service: https://github.com/libvirt/libvirt/blob/master/tools/libvirt-guests.service.in
