This issue has been posted before, but no clear solution, i am sending again.

2.6.32 pvops dom0 booted with xen 4.0. However the xend can not start.
I believe that is something related to the evtchn.
I compile the CONFIG_XEN_DEV_EVTCHN=y in kernel, so i donot need to load it. When the dom0 booted, I can see there is a entry for evtchn in /dev/xen along with gntdev.

But when xend starts, the evtchn in /dev/xen disappeared. and xend is not properly started.
The error log in /var/log/xen/xend.log is the following:

[2010-06-18 10:51:35 4685] INFO (SrvDaemon:332) Xend Daemon started
[2010-06-18 10:51:35 4685] INFO (SrvDaemon:336) Xend changeset: unavailable.
[2010-06-18 10:51:35 4685] ERROR (SrvDaemon:349) Exception starting xend ((111, 'Connection refused'))

I am using a centos 5, which has an old udev. I tried to modified the udev rules in /etc/udev/rules.d/xen-backend.
rules and changed evtchn to xen-evtchn. No luck.

Any ideas?
