[pve-devel] [PATCH qemu-server 10/12] backup: include owned CD-ROM volumes

[Fiona Ebner]

Currently, all volumes with a 'media=cdrom' marker are excluded from
backup. For owned volumes, this is very surprising. Treat owned CD-ROM
volumes like other volumes and consider the 'backup' marker instead.

Cloud-init volumes are owned, but still skipped, because they are
generated from the configuration/snippets.

Stay compatible with old callers avoiding the need for a versioned
breaks.
