ps I notice on one of my Xen 3 working machines:

# ifconfig | grep Link

but on the Xen 4 the xenbr0 is not there, can this be the cause of my hang?

Hi,

I have installed a fresh CentOS 5.6 machine, done all updates. Installed the
kernel-xen (kernel-xen-2.6.18-238.9.1.el5)
and gitco http://www.gitco.de/repo/GITCO-XEN4.1.0_x86_64.repo in
/etc/yum.repos.d.

did yum install xen and rebooted, everything looks ok but when I try to
create a domain using CentOS 5.6 and it hangs
after

mounting /sys filesystem... done

Here are my outputs please let me know if you need anything else or it is a
known issue:
