[pve-devel] [PATCH manager v2 1/2] fix #474: backend: allow transfer from container/vms

[Philipp Hufnagl <p.hufnagl@proxmox.com>]

When a member of 2 pools wants to transfer a
 vm/container to an other pool they can not do that. The vm/container would
 have first to be removed form the current pool resulting in a loss of
 privileges of the pool member for this vm/contianer. This feature introduces
 a way to transfer a vm between pools, guarded by a checkbox from accidental
 transfers

 This is the patch for the backend changes
