[CentOS-virt] Accessing NTFS on host from XP/Win7 VM

Add a full physical disk to the VM:

    <disk type='block' device='disk'>
      <driver name='qemu' type='raw' cache='none' io='native'/>
      <source dev='/dev/sda'/>
      <target dev='hda' bus='ide'/>
      <address type='drive' controller='0' bus='0' target='0' unit='0'/>
    </disk>

*** WARNING *** WARNING *** WARNING ***
Don't never ever try to boot Linux again from that disk in a virtual
machine OR even write anything onto Linux partitions. Trying to
mount/write already mounted partitions = big shit happens.
