pSeries doesn't support ide and so the default bus type was changed to use the

performance outcomes. So, change the default to virtio for disks.

This will break the test suite, you'll need to run 'python setup.py tests
--regenerate-output' to update things
Is this fine to do unconditionally? Or is working virtio support dependent on
new enough qemu or libvirt or guest OS?
Hi Cole,
I could verfiy that, virtio support has been there from the early
versions of qemu(1.6.2) supporting Power KVM.
Also, all of the supported distros support the virtio from the initial
releases itself.
I'll post the V2 as suggested.
Thanks,
Shiva
