Ok, you're not using a COW. COW files aren't supported by the host.

Your only problem is that you partitioned it, so it's slightly more difficult 
to loopmount.

Likely, if it's on the first partition, mount -o loop,offset=512 ubd0 <mount 
point>. The problem is just finding the right offset, and fdisk can help.
