Yeah, this one makes sense.

Frankly, this one looks at the edge of the scope of virsh list. I mean,
I view virsh as a simple CLI utility that you can build your own scripts
on the top of.
Also, you want 5 flags. Cool. But tomorrow somebody else wants another 5
(title, description, has given device, etc.). The possibilities are
endless. I suggest writing your own management application on the top of
libvirt.

And this one is beyond the scope of the command. The aim of list command
is to list available domains, not fetch side note info on them.

I'm ambivalent on this one.
