By default, `pvenode startall` will only start VMs/containers which +have been set to automatically start on boot (see +xref:qm_startup_and_shutdown[Automatic Start and Shutdown of Virtual Machines]), +however, you can override this behavior with the `--force` flag. Both commands +also have a `--vms` option, which limits the stopped/started guests to the +specified VMIDs. + +For example, to start VMs '100', '101', and '102', regardless of whether they +have `onboot` set, you can use: + +---- +pvenode startall --vms 100,101,102 --force +---- + +To stop these guests (and any other guests that may be running), use the +command: + +---- +pvenode stopall +---- + [[first_guest_boot_delay]] First Guest Boot Delay @@ -101,7 +149,21 @@ pvenode config set --startall-onboot-delay 10 ---- -// TODO: extend and improve chapter! +Bulk Guest Migration +~~~~~~~~~~~~~~~~~~~~ + +In case an upgrade situation requires you to migrate all of your guests from one +node to another, `pvenode` also offers the `migrateall` subcommand for bulk +migration.
