Specify virtual disk controller and/or virtual nic type

Windows does not ship with the virtio drivers. Since our installation always will default to virtio devices for i.e the virtual disk controller and the virtual network interface, the windows images in Glance needs to have these drivers pre-installed.

There may be situations where users want to upload existing Windows images without these drivers installed. To be able to boot them without adding these drivers, it is possible to change the virtual hardware devices:

openstack image set --property hw_disk_bus='ide' <image-id>
openstack image set --property hw_vif_model='e1000' <image-id>

This commands will tell KVM/libvirt to use IDE disk controller and E1000 NIC. Be aware that this may reduce the virtual machine performance significantly!
