[pve-devel] [PATCH qemu-server v2] fix 3886: QEMU restore: verify storage allows images before writing

[Matthias Heiserer <m.heiserer@proxmox.com>]

When restoring a backup and the storage the disks would be created on
doesn't allow 'images', the process errors without cleanup.
This is the same behaviour we currently have when the storage is
disabled.
