Take a look at iozone it is a little dated, but still good and is
cross platform so you can can have a level playing field between
Linux, Windows and Solaris.
I'd be interested in hearing your results. I will tell you it will be
slower then bare metal, that is just a fact of life, but with adequate
hardware it may be more then acceptable.
It would allow a VM to fail-over for another though which is key in a
HA situation like storage.
