[pve-devel] Allow dedicated migration network (bug #1177)

[Thomas Lamprecht]

Two notes I possible forgot:

a) this does also the storage migration over the network, but storage 
migration is currently
    always with ssh (+ rsync) there are plans to use a dd + netcat (+ 
maybe also compression in between)
    combination if the migration type is insecure, to speed things up.

b) some patches of this series conflicts quite a bit with Alexandres 
live storage migration series,
    so I can rebase those if his code gets merged, should be mainly the 
patches in qemu-server :)
