Justin (jpiszcz@lucidpixels.com) was discussing the ioscheduler for SSD, 
and I was thinking about that in terms of virtual machines, since I run 
a lot of small servers using KVM. So I added a short script to my 
rc.local, to use the "noop" scheduler for any drive with model QEMU* so 
that the underlying host scheduling can work without anything competing.

I was wondering if that should also apply to the "rotational" feature 
added in 2.6.29, since these "devices" are backed by files.
