To be honest, there aren't many but they are there. Notable examples include the collectd plugin that Richard Jones created in C and hostflow.

There's also virt-top, but I don't think it'll provide you with all the information that you'd need.

Personally, I ended up creating a crude script in python to collect information from KVM pids and network interfaces in /proc/net/dev
