emellor@leeni.uk.xensource.com afa150ca7c Fix the startup behaviour when the tdb file exists. We were attempting to 
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.

emellor@leeni.uk.xensource.com a16c06e77e Fix usleep definition -- we would be sleeping 1000 times too long if the usleep 
command were not available elsewhere on the machine (on my Debian boxes, for
example).

Sleep for a configurable amount of time between xm create calls (by default,
5 seconds).  This spaces out the booting of the new domains, meaning that they
should not thrash the disk so much.

emellor@leeni.uk.xensource.com 11d655cef6 Tidy up use of environment variables in xenbus-hotplug interaction. 
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.

This work is by Christian Limpach.

emellor@leeni.uk.xensource.com 5e61562a32 Change configuration handling wrt to the vcpus entry, so that we only see a 
vcpus entry in the image section when using VMX, only add VMX options at all
if the builder is vmx, and issue a warning when overriding the global vcpus
setting with the one from the image.

This removes the duplicated vcpus entries in the domain's sxpr.

return [ test ] is not valid, simply [ test ] at the end of the function is the

writable.  Reads have been observed exhibiting similar behaviour too.
