The Boot pane shows Autostart and the boot menu as switches that save on change, and the boot order as one list of the VM's disks, CD-ROM drives and NICs: the devices in the order first, checked and numbered, the others below. Up and Down move the checked devices; Apply order saves. - The boot menu can be changed while the VM runs: it is in the persistent definition, so it applies at the next start, as the boot order does. - The boot order editor no longer needs the boot menu enabled. - A VM that boots by device type (<os><boot dev='hd'/>) names those types; checking devices replaces that order. - An order is refused while a device the list does not show (a host device, a floppy) has a boot place, so Apply does not drop it; the message points to the XML editor. - An empty order is refused with a message instead of being ignored. - get_bootorder gives a NIC's full MAC as its target. - The unused jQuery multiselect plugin is removed.
