It adds support for different virtual disk types such as qcow, qcow2,
vhd, vmdk, etc.

pooka@ pointed me to pud(4) when I talked to him last time.

I'm not sure this is the right way to do it; performance-wise.

It's the only one reasonable for now, as they can be handled directly within a process. Otherwise, we have to make somekind of "vnd(4)" plugin, and implement sparse support (which is not as easy as it seems).

if balloon is mandatory now it should be enabled by default in dom0.
What is missing from the balloon driver before we can enable it
by default ?
