A volume of an LVM or iSCSI pool can be attached: by its own path, with
the format its volume reports (raw when the pool knows none). Detaching
a disk takes each definition's own description of it, so a disk only in
the persistent definition goes too. Every NIC type can be a boot device;
bridge and direct NICs were dropped from the boot order. The video model
is a value, never parsed as XML. QoS changes clear the page's read cache.
The NIC model "default" leaves the choice to libvirt instead of writing
model "default", and rt18139 is rtl8139: a VM with either did not start
(checked on a RHEL 10 host). A migration corrects the default NIC type
setting.
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.
SPICE was removed earlier; its leftovers and the console type choice go
too:
- the console settings form, update_console and the backend no longer
offer or change the type; an invalid console form now shows its
errors instead of being ignored;
- the create form, the API serializer and create_instance no longer take
a graphics type, new VMs get VNC; get_graphics_types and the graphics
entries of the domain capabilities are gone;
- migration appsettings.0013 deletes QEMU_CONSOLE_DEFAULT_TYPE;
- a VM defined elsewhere with another graphics type gets "Console type
... is not supported".
The locale catalogs still reference the deleted SPICE templates in
source comments; regenerating them is left to the translation work.
* Add rest framework for API: First Commit
* modify some shell scripts to make variable references safer; modify some python scripts to reduce the code complexity and cyclomatic complexity of functions.
* Add REST API for some webvirtcloud functions. Instance list/delete/create, compute list/delete/create, storages-network list/retrieve. Add swagger and redoc for API interface
* update requirements

move wvmCreate.get_cache_modes() to wvmConnect
add wvmConnect.get_busses(), wvmConnect.get_image_formats(), used in forms
add corresponding default values to settings (INSTANCE_VOLUME_DEFAULT_FORMAT INSTANCE_VOLUME_DEFAULT_BUS INSTANCE_VOLUME_DEFAULT_CACHE)
