xl has at least one big lock around domain creation (to do with dom0 memory
ballooning IIRC), there may also be others in xl and libxl.

Resolving this has been a long standing TODO development item, but AFAIK no
body is working on it.

If you are interested in tackling this problem then I would suggest
bringing it up on xen-devel where hopefully other folks will remember more
of the details regarding the current situation and planned improvements.
