[PVE-User] Live Migration Problem

[Kilian Ries]

Thanks for the hint, there was an error with the sources.list. Now i'm really on the latest version:

pveversion -v 

proxmox-ve: 4.2-56 (running kernel: 4.4.13-1-pve)
pve-manager: 4.2-15 (running version: 4.2-15/6669ad2c)

However, after live-migration from host1 to host2 the VM is still frozen:
