The status is that I'm hammering my head on the desk for two weeks now 
what the heck is going wrong here.

What I've found so far is that a VM update command doesn't have the 
result it should have, but I absolutely don't understand what happens here.

The good news is that it's 100% reproducible and I already found and 
fixed two bugs.

If you have any idea or more testing results what is going wrong here 
please let me know.

If we can't fix this before the 4.9 release we are just going to revert 
the patch causing this.

Regards,
Christian.
