VM Migration - churchers/vm-bhyve GitHub Wiki
Migrate a VM from host to remote host.
A guest can be transferred completely from the source host using a single command.
vm migrate -s guest-name new-host
Ideally passwordless key-auth should be used, although not strictly necessary.
See the man page for more details:
vm migrate [-s12t] [-r name] [-i snapshot] [-d datastore] guest host
