Xen release 3.0.0
With 'xm rename' and 'xm restore' commands, it's possible to start several
domains with the same properties (same config file).
Example:
- create a config file named 'A'
- xm create A
- xm rename A B
- xm save B B.save
- xm create A
- xm restore B.save
At this time, there is two domains A and B with the same properties
(same hard disk, same IP address, etc..).
The correct behavior would be to reject the "xm restore B.save".

The hotplug scripts should be protecting you from writing to the same disk by
two domains at the same time. What does your config file look like -- how is
that not happening?
