Many times when we move or copy a guest we need to keep the same
UUID. As
an example we have a VM that is running Centos 4 that we need
upgraded to
Centos 6.2. How we have done this in the past:
Build new VM
Install fresh Centos 6.2
Copy over the application
Shutdown the first VM
Shutdown the 2nd VM and change UUID to match first
Fire up 2nd VM if everything works kill delete 1st VM
What you want is the ability to copy the VM configuration, not to change the UUID.
The point of a UUID is that it is a Universally Unique ID, hence there should be only 1
such in the universe.
Instead of suggesting a solution, it is better to explain the problem.
Having the ability to clone the configuration of a VM would be a lot more useful (e.g. it
can be done multiple times and wouldn't be limited to a single VM).
We run into all sorts of other situations when we make copies as
backups
and need to go to one of the backups. We never need to run a two VMs
with
the same UUID, but often have a box where we need to change the UUID
to
match what an old box was using.
