Is it possible to edit VM config files?

I want to have the possibility to live restore VMs to a different vmbr interface for testing purposes. But the problem is that you can only live restore a VM to the same vmbr interface and the VM stays locked until all the restore has finished.

There would be a couple of options:
1. Change the VM config file during/before backup
2. Edit the backed up configuration file of the vm

Is such a thing possible?

Another alternative would be to add another PVE host which has a same vmbr1 interface our production VMs have but on that specific node vmbr1 does not connect to our real production network.
 
Is there any reason why this is not in the manpage or documentation?
Well, the man page for the qm create command does list all other options alongside --archive suggesting they can be used together. But yes, the documentation for restore could also mention this, feel free to open an enhancement request on the bugzilla to add that.
