Finally the 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?

I haven't tested it, but it should work since the version is close
enough. Put it as .config on directory, and run "make
menuconfig". It should fill out missing new values automatically, plus
give you the chance to review the current config. Exit and save the
config, and you should be ready.
