My thinking is that the sources from F19 would be better since RHEL7 is based on F19 they would be a lot closer to RHEL7 than the CentOS 6 Xen sources, although both would probably build with no modifications at all. One thing that the parent didn't mention is where he got the dom0 kernel from. The best place would be just to rebuild the RHEL7 kernel with Xen dom0 support enabled. It is possible that libvirt would need to be rebuilt with Xen support enabled as well, and as I said above, everything else (the Xen tools and hypervisor) could be gotten from Fedora 19. > with the caveat that it did not have a "gcc" > dependencies, which I've added to a .spec file, gcc is considered to be part of the standard build toolset and as such is not required to be listed as a dependency in any spec file. > and the .spec file for > dev86 and for Xen both have badly formatted dates in the "%changelog" > stanza.

The F19 spec files should be fully compliant with the EL7 guidelines. > Once I'd satisfied all the dependencies for the SRPM, I was able to > build the Xen 4.3.1 tarball pretty easily.

Admittedly F19 comes with Xen 4.2.3, rawhide comes with 4.3.1, though, and can probably be directly rebuilt for EL7 without any fuss. > But with all that said: why are you bothering with Xen when RHEL and > thus CentOS have KVM support built right in?

There's no reason to exclude it just because upstream made a political decision.
