Based on a discussion in another list on ioschedulers, I added a few lines to my rc.local to set the scheduler to "noop" for disks with model QEMU*, to the scheduling in the VM will not be computing with the scheduling in the host.

I wonder if the same thinking applies to the "rotational" feature added to /sys/block in 2.6.29, intended for SSD but probably appropriate for virtual and nbd devices as well.

A virtual disk backed by a rotational physical disk probably should be marked rotational, at least with cache=off.
