I'm not likely to be able to work out what is wrong, but I think
first thing you will be asked is for output of "xl create -vvv", and
also if anything useful appears in "xl dmesg".

FWIW on Debian 8 with Xen 4.4 and lately a backported Xen 4.8 I am
running 70+ PV guests without issue. (Other than that the
initscripts xendomains etc aren't really up to this).

Cheers,
