F8 fresh install, fdisk shows /dev/dm-X devices

[Ahmed Kamal]

Hi,
I just installed F8 fresh installation. The previous system (where the LVM
volume where created was FC6). After I booted into F8. "fdisk -l" returns
unusual /dev/dm-? devices. These seem to be the LVM's physical volume
partitions. Not sure why they're being picked up here! Here's the full
output

 fdisk -l
