I handled this by writing an /etc/security/limits.d/ file during host
install, which seems to have done the trick. I just sent a patch which
along with the libvirt one I sent earlier today covers everything I
think we care about except our daemons which are launched from
xencommons.

The initscript in xen.git doesn't offer a useful hook for this, we could
add something to the end of /etc/default/xencommons, which is sourced by
the script, but that seems like a bit of an abuse.

Ian.
