[pve-devel] [PATCH qemu-server] close #2263: die on live migration with local cloudinit disk

[Mira Limbeck]

Live migration with a local cloudinit disk was never intended to work. It did
however work to an extent that the migration completed but the disk on the
source node could not be deleted. Now die if a live migration is started with
a local cloudinit disk.

With the GUI changes live migration is already disabled as it recognizes the
cloudinit disk as a local resource.
