This step isn't required, it is one of the things virt-clone should take
care of for you.

Not sure why you are seeing that, what is the output of 'virsh --connect
qemu:///system list --all'. What virtinst version are you using? If it's
prior to 0.400.3, I'd recommend an upgrade, since virt-clone was pretty
rough around the edges prior to that release.
