You can sort of get the io from something like Nagios however the
problem is if the vm goes wacky you can only get the stats properly

Can't you get these metrics from nagios?

I would also be interested for that feature since we run some VM with
high I/O load it would be great to see those metrics in the interface.

Hi,
Would it be possible add the io stats of a vm into
ovirt-guest-agent for making that data available in the interface
of oVirt?
I could help out by getting the stats into the client package, the
server side would be a bigger issue to me.
