You should normally use vm delete to delete a virtual machine, not this command. But if you really want to remove a machine without any option of changing your mind later, type (e.g. to purge a machine called phonehackr):
$ bigv vm purge phonehackr
VM phonehackr was deleted
or to purge a virtual machine that's not in the default group, type:
$ bigv vm purge phonehackr --vm-group illegalactivities
VM phonehackr was deleted
There will be no confirmation, and no option to recover the machine at a later date (not even by Bytemark staff) so use this option with care.
