How could a VM supervisor know whether a VM is actually "working"?
That's one of the purposes of the guest-agent.
Give the " monitor" a try, anyway.

I forgot to mention the Monitor, if available.
The "info status" would give you a lean status of the VM: either
running or paused.
I think the best way is QMP and, of course, the qemu-guest-agent
running inside the VM.

Ping cannot be a solution.
If you have QMP in place, just issue a "query-status".
If not, you need to use the ol' school VNC console (or whatever applies).

I still think that libvirt is not doing something qemu-kvm cannot do on its
own.
And I am willing to know how, as I said earlier.

But my main objective is to do the backup while the VM is running.

I'd like to know how to virtually disconnect and connect the ethernet
cable on a VM (I am using virtio).
When "disconnected", the ethernet adapter should still be visible by
the guest, but with the cable being disconnected.
I mean, both the command line and the monitor commands.
TI
I use something like this:
... -vnc 127.72.42.2:0
where 127.72.42.2 is the IP where the VNC server will be listening to.
The ":0" is to select the first local console.

There is an overall benefit with virtio as it is more efficient on both the
host and the guest.
Then, during the installation, before the media selection and the actual
partitioning you are given a chance to install extra drivers. That's the
