1) Added script create_disk_image to make full virt image
2) Changed XenDomain.py to build separate XmTestDomain object
for vmx guests (this structure will need to be cleaned up)
3) Changed ramdisk Makefile.am to create disk.img if vmx configured

* For setsid to effectively detach a process from the terminal,
the following needs to occur:
fork () Return control to the shell
setsid () New session with no controlling terminal
fork () The session leader (parent) exits and thus
the resulting child process can never regain the terminal
This patch adds the second fork
* The call to self.daemonize(), which now forks, is moved to
run before self.tracing(), as now that it actually disconnects
from the terminal, and thus the prevailing process, the trace
loses the processes created in self.run().

it, when using ip on the kernel command line and not using the installed ifup /
ifdown. This stops the script bailing out if there is already an address
attached to that device, which was leaving the device without routing (since
this has already been removed).
Fix the stop action under the same circumstances. No attempt was made to
restore the kernel command line details to the interfaces if the ifdown failed
in that case.

remove and recreate the /local directory, but the manual_node call only works
if the tdb is empty -- we must use create_node, otherwise the store is
corrupted.
It's not clear to me that the other manual_node calls are safe, but I have only
made this smaller change for the sake of stability. These other calls should
be reviewed.

I've changed this to only write "backend" (xenbus_backend.root) into
XENBUS_BASE_PATH. After appending XENBUS_TYPE (also exported) you can
construct the "base path" easily in the scripts. I've completely
removed writing XENBUS_FRONTEND_ID in favour of reading it from the
store at "$XENBUS_PATH/frontend-id".
Avoid re-reading the store over and over for the frontend domain's vm-path.
The patch also fixes a memory leak in backend_bus_id where we
leak the memory referenced by frontend if the function succeeds.
