libvirt users - Jan 2012 - Clone VM

Greets,

	I've began to try libvirt API and looking for most correct way to clone 
existing VM (Xen server if it matters).

	Since API lacks this functionality how does one usually go about it? 
Thanks in advance,

We have a lot of strategies, but always the same tactics.

There isn't a single 'clone' api. You would basically need to copy
the guests
underlying storage using something like virStorageVolCreateXMLFrom, and define
a new guest based on an edited version of the original domain XML. You can
check out the virt-clone tool for an example:

http://git.fedorahosted.org/git/?p=python-virtinst.git;a=blob_plain;f=virt-clone;hb=HEAD

And that is only the superficial duplication from outside the VM, no changes
are done to the guest OS.
