Of course it doesn't. That's a virtual *disk* and it's quite likely that 
the guest operating system created partitions in it. You can't mount the 
disk directly.

You need to map the partitions with partprobe or partx, then you can 
mount them. Just be really careful and when you're done, remember to 
remove the additional dm-X devices created for the partitions with 
something like
  dmsetup remove vm-105-disk-1p1
