On VirtualBox, I've exported a Ubuntu Server VM (File \ Export Appliance) and tried to imported it on a different machine. every thing went well with export and import. But, when I start the imported VM, I get this VERR_NOT_SUPPORTED error VERR_CFGM_VALUE_NOT_FOUND. Its quite weird. If I ditch the Import process and straight away create a new VM and use the exported VMDK, it works fine!! Both machines are using the same version of VirtualBox (3.2.4 r62467) Any clues?
