Wanlong Gao is correct that using libguestfs on a running
VM will (not maybe, *will*) cause disk corruption.
However you might want to look at libguestfs-live, which
involves installing a daemon in the VM that libguestfs talks to:

(Currently this only works for Linux VMs)
Also, if the VM is switched off, you can install a firstboot
script (as previously discussed). This script runs when the
guest boots, and can install software etc.

virt-top is 'top' for virtual machines. Tiny program with many
powerful monitoring features, net stats, disk stats, logging, etc.
