Windows Server 2012 install onto Qemu with Virtio drivers

In this video I am installing Windows Server 2012 onto Qemu and am installing the virtio drivers for the hard drive, network and a balloon memory pci controller that allows the VM to release its memory back to the host. The virtio hard disk driver sure seems to have made a difference to the speed of the installation, though I did put the virtual hard disk onto a RAID 0 SSD array and the install ISO image was copied to a tmpfs.
