I'm trying to track this down, but 1) I can't reproduce it
on my setup and 2) it doesn't make any sense :)

It's almost as if libvirtd.service would be started during
boot, but not every single time. Except you always have it
running after boot, right?

And After=libvirtd.service tells systemd *exactly* to wait
until libvirtd has started before starting libvirt-guests,
so the situation you apparently find yourself in should
never, ever happen, barring a systemd bug.

Since you're running an Arch variant, I'm going to assume
all your software is basically at the latest version all
around, isn't it?

Can you try adding


to your libvirt-guests.service via 'systemctl edit' and
see if it helps? I don't think it should be needed for your
use case, but it's probably a good idea to have it there
