Personally, I feel like most of this is way out of scope for
libvirt.

If you want to monitor the disk / memory usage of your guest,
just run the Nagios agent or whatever in it; if you want to
run random commands, just use ssh.

These are not some specific requirements that are strongly
tied to virtualization, but very generic requirements that
can be addressed with existing generic software.
