Im actually running the disk images on top of lvm partitions, but this
particular use case requires file based disks for our customer,
basically a reseller of our service. He wants to offer HIS customers
the ability that if they blow up their windows xp box, he can just
relaunch the vm pointing to the backup disk image.

To do this, it seemed much easier to be able to do a cp live-disk.img
backup-disk.img versus doing a dd or ? to create a backup.

Hm actually does anyone have any input on that? is "cp file1 file2"
faster than a "dd if=/dev/volumes/file1 of=/dev/volumes/file2"?
