According to the log files you are deploying a VM with a delta (snapshot) disks, which has another 6 links (snapshots in the chain)!? To me this doesn't look like it is really intended to be this way. Can you please explain the purpose for this i.e. why it is done this way. This doesn't only decrease performance, but also is risky because you will loose the VM if only a single chain-link gets lost.
