Hi Anthony,
Sounds like you're the right person to get the interface
documentation written? :). Would be very helpful.
thanks,
Nivedita

2) Build domain
 lconsole = rconsole = 0;
 xc_evtchn_bind_interdomain(0, domid, &lconsole, &rconsole);
 lstore = rstore = 0;
 xc_evtchn_bind_interdomain(0, domid, &lconsole, &rconsole);

xc_linux_build(domid, kernel, ramdisk, cmdline, 0, vcpus, rstore, &mfn_store, rconsole, &mfn_console)

 home = "/tools/<yourtool>/domain/%d" % domid
 xs_domain_introduce(domid, mfn_store, lstore, home);
 xs_write(home + "/console/ring-ref", mfn_console)
 xs_write(home + "/console/port", lconsole)
3) Create block device (pdev, vdev)
 static int uuid;
 dom0_home = xs_get_domain_path(0)
 backend = dom0_home + "/backend/vbd/%s/%s' % (uuid, domid)
 frontend = home + "/device/vbd/%s' % uuid
 transaction_start()
 xs_write(backend + "/frontend", frontend);
 xs_write(backend + "/frontend-id", domid);
 transaction_end()
 transaction_start()
 xs_write(frontend + "/backend", backend);
 xs_write(frontend + "/backend-id", 0);
 xs_write(frontend + "/virtual-device", vdev)
 transaction_end()
 xs_write(backend + "/physical-device", pdev)

This might seem complicated, but compared to what you had to do under 2.0.x, it's a 1000x times easier.
