Does this help?

echo "cfq" > /sys/block/sda/queue/scheduler

Alternatively you can use elevator=cfq as the command line option for both the dom0 and domU kernels in grub.conf and domU config file respectively. This will force the use of cfq as the default scheduler.

By default anticipatory is the scheduler in dom0 and noop in domU.

You can also try to do cpu scheduling for the domU's which will allow other domains to get the cpu share they deserve.
