Now
# diff -auN config.received config.071310  > conf.patch
# cat conf.patch

. . . . . .

-# CONFIG_XEN_NETDEV_BACKEND is not set
-# CONFIG_XEN_BLKDEV_BACKEND is not set
-# CONFIG_XEN_BLKDEV_TAP is not set
+CONFIG_XEN_NETDEV_BACKEND=y
+CONFIG_XEN_BLKDEV_BACKEND=y
+CONFIG_XEN_BLKDEV_TAP=y
+CONFIG_XEN_BLKBACK_PAGEMAP=y

I attached mine config and config.patch.
Make diff one more time on your box and watch errors for yourself

The best option - just use config attached after git pull ( 2.6.32.16 )

2. Second.
Please submit your working grub entry for Xen (just one)  and "df  -h" for corresponding vanilla entry. /dev/sdb5 and (hd0,1) seem strange to me.

Boris.

1. I would suggest you to obtain a serial log and escalate the problem to xen-devel.
2. Could you post yours /usr/src/linux-2.6-xen/.config ( gzipped) ,/boot/grub/grub.cfg,
"df -h" output.

Boris.

I have tried 4 time unsuccessfully to install Xen 4 on Ubuntu Lucid (10.4) 64 bit version using the tutorial at 

When I boot I get a kernel panic. If I boot the Linux kernel that I compiled using the tutorial on it's own it boots fine. 

Is the likely cause hardware? is there a common error made in this tutorial that would cause a panic on boot.
