Fedora xen - Oct 2009 - xend fails to start in rawhide/F12 on x86_64

Hello,

I was just playing with Fedora on x86_64 box, and I upgraded it from F11
to F12 rawhide.

I installed xen rpms and myoung xendom0 kernel, added /etc/fstab
/proc/xen entry and rebooted into xen.

Now it seems xend doesn''t start for some reason. Has anyone noticed
this?

[root@f12test ~]# /etc/init.d/xend start
Starting xend daemon:                                      [FAILED]

[root@f12test ~]# tail -29 /var/log/xen/xend.log

Thanks. selinux was the culprit. Disabling selinux fixed the problem,
and xend starts now.

I usually always disable selinux as a first thing, but now I forgot.
Doh. :)
