Creating each option on a RHEL qemu-kvm host showed:
- CD-ROM: the create page offered every disk bus, but the empty CD-ROM
of a new VM works only on ide, sata and scsi. fdc and virtio failed
("Invalid bus type", "does not support ejectable media"), usb failed
with a device named 'Nonea' because vol_dev_type() had no prefix for
usb, and after that libvirt refuses an empty usb disk. Only ide, sata
and scsi are offered now, and another value is refused before any
storage is allocated. vol_dev_type() names usb disks sdX, which also
fixes data volumes on the usb bus.
- USB controller: any input device added a bare <controller
type='usb'/>, which libvirt turns into piix3-uhci (USB 1.1) on q35
instead of its default qemu-xhci. The bare controller is gone; libvirt
adds the machine's default for USB inputs.
- MACs: with more networks than MAC addresses, create_instance indexed
past the list and the request failed with a 500. NICs without a given
MAC now get one from libvirt. MAC addresses are validated (format, not
more than networks) by the page and the API before anything is
created; they went into the XML unchecked.
Unit tests cover the refused values, the MAC rule and the usb prefix.
Live tests create a VM with every offered CD-ROM bus and start it,
check the USB controller with a USB input device and create a VM with
two networks and one MAC.
