A disk without driver/@type could not be edited: the empty format was
rejected, and edit_disk would have written type=''. An empty format is
now accepted and edit_disk leaves the type attribute out.
The edit_volume bus change detached the disk and attached a new one built
as a file disk, so block and rbd disks lost their source and auth, and a
failed attach left the disk detached. Add wvmInstance.change_disk_bus,
which reuses the disk element and only changes <target> (dropping the old
bus address), and re-attaches the original disk if attaching fails.
edit_disk also rebuilt every disk with <source file=...>; it now keeps the
existing <source> and <auth> of block and network disks.
Disk and media mutation views (add_new_vol, add_existing_vol, edit_volume,
delete_vol, detach_vol, add_cdrom, detach_cdrom, mount_iso, unmount_iso)
were reachable by any owner with is_change, although the UI only shows the
Disk tab to superusers. An ordinary user could delete any volume on the
compute or attach arbitrary host files to their VM.
- Require superuser for all disk/media views, matching the UI.
- delete_vol resolves the volume from the VM's own disk XML by dev and
ignores the posted storage/name.
- Validate bus/cache/io/discard/detect_zeroes against the hypervisor's
lists, and format/serial/volume name against strict patterns.
- add_existing_vol only accepts volumes that exist in the selected pool.
- edit_volume only accepts a dev attached to the VM.
- vrtManager: escape all values interpolated into disk XML and pass dev
as an XPath variable in detach_disk/edit_disk.
* 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
