The latest bunch of test packages are available here:

Hopefully, as of a few hours ago, this set should actually install.

Currently, networking won't work as they require brctl - which isn't in 
EL8. I've written patches for this, but they'll probably end up being 
part of a cleanup of everything in /etc/xen/scripts/

Problem is, they're probably too late for the 4.13.0 release - so I'll 
have to carry them myself for a while until they hit the git staging 
area within Xen.

I don't have a kernel capable of being a Dom0 as yet - so that's still 
at a roll your own or obtain elsewhere status.

The source for all this is here:

Yes, I take patches.
