While testing Fedora 20 with xen 4.4 RC2 I hit what looks like the same or
similar issue.

[root@astar ~]# xl create mars.xl
Parsing config from mars.xl
libxl: error: libxl_create.c:1034:domcreate_launch_dm: unable to add disk
devices
libxl: error: libxl_dm.c:1467:kill_device_model: unable to find device model
pid in /local/domain/1/image/device-model-pid
libxl: error: libxl.c:1425:libxl__destroy_domid: libxl__destroy_device_model
failed for 1
libxl: error: libxl_device.c:780:libxl__initiate_device_remove: unable to
get my domid
libxl: error: libxl.c:1461:devices_destroy_cb: libxl__devices_destroy failed
for 1
[root@astar ~]#

I was able to get the guest to boot by doing this:

[root@astar ~]# /usr/bin/xenstore-write "/local/domain/0/domid" 0
[root@astar ~]#
[root@astar ~]#
[root@astar ~]#
[root@astar ~]# xl create mars.xl
Parsing config from mars.xl
[root@astar ~]#
