Re: [Xen-devel] Domain Save-Restore

* SV is the (experimental) web interface and is located in
tools/python/xen/sv/.
* Xend is the control daemon and handles all sorts of control-plane things
including receiving commands from SV and the xm command line tool and
dispatching them to the rest of the system. Xend lives in
tools/python/xen/xend/.
* Xfrd is the migration / suspend daemon and is written in C for performance
reasons. It accepts commands dispatched from Xend itself. It lives in
tools/xfrd/ and contains the actual code for suspending / migrating a domain.
