`multipass restart` command

The multipass restart command without any argument will restart the primary instance (and fail if the it does not exist yet). You can also pass one or more instance names or the --all option to restart more instances at the same time. Only Running instances can be restarted.

$ multipass restart vm1

The full multipass help restart output explains the available options:

$ multipass help restart
Usage: multipass restart [options] [<name> ...]
Restart the named instances. Exits with return
code 0 when the instances restart, or with an
error code if any fail to restart.

  -h, --help           Displays help on commandline options
  -v, --verbose        Increase logging verbosity. Repeat the 'v' in the short
                       option for more detail. Maximum verbosity is obtained
                       with 4 (or more) v's, i.e. -vvvv.
  --all                Restart all instances
  --timeout <timeout>  Maximum time, in seconds, to wait for the command to
                       complete. Note that some background operations may
                       continue beyond that. By default, instance startup and
                       initialization is limited to 5 minutes each.

  name                 Names of instances to restart. If omitted, and without
                       the --all option, 'primary' will be assumed.
