http and unix are s-expressions or HTML pages over HTTP/TCP or HTTP over Unix
domain sockets respectively. These are deprecated.
tcp-xmlrpc and unix-xmlrpc is XML-RPC over HTTP/TCP or HTTP/Unix
respectively. These are what you want to use. You can:
a) use unix-xmlrpc, with Anthony Liguori's recent patch to transparently SSH
into your local machine and issue commands to the Unix socket. This uses
your SSH authentication scheme. See xm serve for details.
b) enable and use tcp-xmlrpc, using the attached patch. This will listen on
port 8005, and will use no authentication / encryption at all (SSL support
is planned). Only use this on a secure network, obviously.

It's a proprietary protocol -- a small handshake and exchange of VM config,
and then a dump of all the pages in memory. You'll have to dig into the code
for details -- tools/python/xen/xend/{XendCheckpoint,XendDomainInfo}.py and
tools/libxc/xc_linux_save.c should start you off.
