Is this next bit where you create your new domain?

OK.
The fact that Xend died here due to Signal 11 (segfault) is quite worrying in
itself. It juggests that some kind of bug has just happened... weird.
I guess that suggests that whatever bit you skipped above might have had
something to do with it. Sorry, it's not the direct cause of the error
you're seeing, so I understand why you skipped it. But I suspect it has
something to do with the root cause.

For some reason, maxmem_kb is 0 in the domain it's trying to recreate, so it
seems not to have any memory. It also says the domain is paused... Perhaps
Xend crashed with signal 11 part way through creating a domain for you - is
that a possibility?
Xend seems to have got itself into a funny state, possibly due to the earlier
crash. Ideally, it should probably handle this sort of thing better, though.
Are you still having this problem? Have you tried updating your pull of
xen-unstable?
And in your setup, have you enabled any particular security policy at all?
I'm afraid I don't understand the security policies very well, so this is
slightly unfamiliar territory for me.
Cheers,
Mark
