Hi Andrea,
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?
Yep exactly, all software / kernel are in latest version
Can you try adding
[Unit]
Requires=libvirtd.service
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
anyways.
I have tried and as you expected it didn't changed anything, same issue.
I made more test and it is very reproductible, let me give you my steps
to reproduce it :
-I shutdown -r now my host.
-when it restarted, first thing to check is : systemctl status
libvirt-guests.service, I got :
libvirt-guests.service - Suspend Active Libvirt Guests
Loaded: loaded (/usr/lib/systemd/system/libvirt-guests.service;
enabled; vendor preset: disabled)

Even if the service is in FAILED mode, my guests are started correctly.
If I do a systemctl restart libvirt-guests.service, everything is good :
libvirt-guests.service - Suspend Active Libvirt Guests
Loaded: loaded (/usr/lib/systemd/system/libvirt-guests.service;

Sep 15 17:42:01 systemd[1]: Starting Suspend Active Libvirt Guests...
Sep 15 17:42:01 systemd[1]: Started Suspend Active Libvirt Guests.
Now if I do a shutdown -r now again, I can see both in my libvirt logs +
in my guests log that an ACPI commands has been sent from libvirt and my
guests shutdown gently, so everything is ok.
When I start again, and try to do a systemctl status
libvirt-guests.service, I got the same FAILED status as before....
I made a research on my logs :

We see the same error as systemctl status plus some error like "
internal error: End of file from monitor" and others type.
Don't know if I have anything to take a look there ?
Finally, I also notice some very strange thing:
If I stop the service with systemctl stop libvirt-guests.service it
tooks a while to execute the stop command and fails.

Sep 15 18:01:15 libvirt-guests.sh[978]: Shutdown of guest ape failed to

So my guests are not able to shutdown properly but when I shutdown -r
now my host I can see that my guests have been shutdown gently, I guess
there is something related on my issue....
Many thanks for your help again
