Yes, via <blkiotune> in the XML, or 'virsh blkiotune':
http://libvirt.org/formatdomain.html#elementsBlockTuning
facepalm .. thx
But note that <blkiotune> is not necessarily the best way to tune I/O;
if you have new enough qemu, you might find better results with
per-device tuning by using <iotune>, or 'virsh 'blkdeviotune':

Uh whats so bad about blkiotune?
As Im stucked to LXC Ive got no great choice.
