[pve-devel] [PATCH-SERIES v2 qemu/qemu-server/widget-toolkit/manager] more flexible restore

[Fabian Ebner]

Allows preserving disks and overriding VM settings upon restore.
For containers, overriding settings was already possible, but managing
partial restore is more involved because of nested mount structure,
etc.

Exposes the functionality in the UI, allowing to set (host)name,
cores(+sockets), memory, and, for VMs, whether disks should be
preserved.

Also includes related improvements, like cleaning up snapshots on
drives and cloundinit correctly and, in the UI, detecting if a storage
needed by the restore is not available.


Changes from v1:
    * Use skip=<drivename> to communicate skipping restore to VMA
      rather than treating path /dev/null in a special way.
    * Use explicit preserve-drives parameter for VM create API to
      avoid automagic and conflict with existing syntax for LXC.
    * Add UI patches.


Necessary dependency bumps are pve-manager -> widget-toolkit
and pve-manager -> qemu-server -> qemu.


Still missing: add documentation for the new restore functionality
for VMs and existing restore functionality for containers.
