How to mount VMDK (VMware disk file) under Linux

Provided you have some VMware product installed (VMware Player will suffice)
sudo mkdir /mnt/vmdk
sudo vmware-mount the-disk.vmdk /mnt/vmdk/
If the disk has only one partition, that's everything you need.
To unmount:
sudo vmware-mount -d /mnt/vmdk/
To list partitions on a VMDK file:
vmware-mount -p the-disk.vmdk
To mount nth partition (they say the numbering starts from 1):
sudo vmware-mount the-disk.vmdk n /mnt/vmdk/
