Re: [libvirt] Create a copy of a Domain



Thanks Daniel,

I think you must at least change the UUID (/domain/uuid) and name
(/domain/name) in the XML description. Very like you also need to duplicate
the used disk images and update their paths
(/domain/devices/disk/source/@file) accordingly, unless you really want your
domians to share them.

I will definately try this out. As for changing the UUID, I think the new value has to be unique in terms of all other Domains present. I am right??

Better yet use the 'virt-clone' command line tool, or virt-manager's clone
capability

As for using 'virt-clone', is there a way to implement this using python bindings for libvirt??
I want to provide the functionality in a python script.
I thought of doing this by directly executing the command line 'virt-clone' command from my python script and check wheather it executes successfully or not. We can do this by the 'os.system' function in python.


Thanks and Regards
Sagar Barve
