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?
Thanks.

Yeah. We added a patch that would change the name to 'xen/evtchn'
instead of 'evtchn'. (git commit
376d908f52427591cef4acd172db9c3ef28676ec)
I am not really sure what corresponding change in userspace goes
with it..

http://xenbits.xen.org/xen-4.0-testing.hg?rev/0e1521f654f2
which means you need xen-4.0.1-rc2 or later or 4.0.0 with this patch
applied (there is a patch in the 3.4 hg that you can apply to 3.4.3 as
well).
