Hi Rich,
I think cloning is a great feature. From when I used to sysadmin a Xen server, I used cloning as the main technique to create new servers - ie. take an existing machine which is similar to the new one which I want, and just clone it.
Thank you for your comments and agreement.
There is no problem with interaction with the remote patch. Nor do you have to worry about the remote stuff when implementing this (the "dd" will fork on the remote libvirtd automagically).
O.K. I understood it. I warry about remote support for libvirt architecture always.
So the idea is that you can only clone an inactive domain?
This first revision, only inactive domain. But next step, I think snapshot command will be able to used instead of "dd".
Thanks, Kazuki Mizushima
