Hello, I noticed a few things about your xen build: >xen_major : 4 >xen_minor : 4 >xen_extra : .2-pre >xen_version : 4.4.2-pre that xen version has no support for systemd. Nor does it have a target to make an RPM. Move to 4.5 and you will have both of those. Since you are on rhel7 this might help, especially if you want to separate the build environment from the dom0.

The same guest configuration will start fine with 4 bridges passed. I have researched this quite a bit and have not found the solution. Any help is greatly appreciated. The error message that I am seeing is as follows.
