packagers are not programmers. but we do need some pre-release testing and xen 
isn't that easy to test without the proper hardware for it.

iirc, not all init scripts need to be started. xend is not one that is needed.

that's way too long, since we're now using systemd, would it be possible to 
install bootchart and reconfigure with dracut your initrd, to find out why it's 
taking so long to boot?

the new xen should rely on a bridge being made in the system config (i think)

I know a bit about it, but i haven't been able to test it much. I wish i 
could, and i have a machine at work i can do it for, but it'll take months 
before i have the time to test it :-( (too much work at work)
