I am saying that under the right conditions mdadm is faster than
hardware RAID, if one is doing RAID 5 or 6, hardware RAID will always be
faster than mdadm. There is almost no overhead with RAID 0, 1 or 10
while using mdadm. MDADM RAID 10 in most cases will be faster than
hardware RAID. MDADM does support hot-swapping with SATA Disc's and
online array rebuilds, it can also send you an email as well if a disc
fails in the RAID set.

I cant remeber if libvirt-bin is installed by default when one selects KVM from the tasksel.
I will try can check later today and let you know.

Here is the link for the virtio driver for windows with the required
links for the info on how to get the drivers to work with Windows 2008
