VMware Fusion: Resize a virtual disk

Vdiskmanager is now available as a command-line tool with VMware “Fusion” Beta 2. It is available from /Library/Application Support/VMware Fusion as vmware-vdiskmanager.

Make sure you have a back up of your virtual machines before running vdiskmanager against your virtual machines, since “Fusion” is beta software. See below for the help from the vdiskmanager command line tool:
