Are you sure? The stack trace indicates that this is "Xen-4.2-unstable"
not 4.1.x. (note to self, we really ought to print the hg cset in the
panic log if it is available...)

For your production uses I think the best advice right now would be to
use 4.1 with xend (unless Stefano can diagnose your xl console issue in
the other subthread). However it would also be useful to evaluate your
use case using xen-unstable and xl so that we can be reasonably sure
that when 4.2 is released you will be able to deploy that without issue.
