This is pretty awesome - useful for recovery.

Here's my extra notes.
First, mount the flat vmdk file as loop0, eg:
losetup /dev/loop0 /srv/data/deadserver-flat.vmdk
Now, investigate the structure with parted, eg:
# parted /dev/loop0
GNU Parted 2.1
Using /dev/loop0
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted) unit bytes
(parted) print
Model: (file)
Disk /dev/loop0: 12884901888B
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Number Start End Size Type File system Flags
1 32256B 131604479B 131572224B primary ext3 boot
2 131604480B 238533119B 106928640B primary raid
3 238533120B 12880788479B 12642255360B primary lvm
The figures in the start column can be used as offsets into the loop device to get to the partitions stuck in the vmdk file.
Next, mount the partition from within the vmdk as another loop device, eg:
losetup -o 238533120 /dev/loop2 /dev/loop0
Finally, confirm it worked:
# blkid /dev/loop2
/dev/loop2: UUID="oc9FXU-tSLN-jdy9-1Zpy-XpA1-qgkI-Ng2l4w" TYPE="LVM2_member"
Cool. Now you can use loop2 as a block-device.
