I also tried this way (make linux-2.6-pvops-build), the problem is still there.

Yes, I always mkinitrd for it through "mkinitrd initrd-2.6-xen.img
2.6.18.8-xen".
It can boot with manually built pvops dom0 on my another platform, but I found
xend cannot be started, there is no directory xen under /proc. That means
drivers/xen are not installed, althrough they are built.
I just want to know anyone has successfully made Xen with pvops work, and can
you share your instructions? Thanks.
