View Xen via libvirt for OpenStack juno
I also focus your attention on Xen 4.4 install on Ubuntu 14.04 . It's supposed to be done from source:-
It's not quite clear what OS are you running , in case Ubuntu 14.04.X it would be most probably Qemu patching issue ( view section 3 ) , if your OS is different then verify presence of commit "xen_disk: fix unmapping of persistent grants" in version of Qemu installed.
Per link been provided current qemu releases as of time of writing 11/2014 (including 2.0.2, 2.1.2 and 2.2.0-rc1) do not have this patch included and this will result in Dom0 kernel crashes when creating a Xen Project DomU from OpenStack GUI (horizon). Even on F21 I have 2.1.3. Qemu rebuild per section 3 (link) seems to be needed. I was able reproduced suggested build


cd qemu-2.0.2-master/
apt-get build-dep qemu
make -j4

on Ubuntu 14.04.2 and F21. Required commit is here (2.2.1):-

I am not using qemu at all.
