[Xen-users] install xen 4.2.1 on ubuntu 12.04

[张伟 <zhangwqh@xxxxxxx>]

Hi all, 

I want to install xen 4.2.1 on ubuntu 12.04. The default linux version is 3.0.29. After I install xen 4.2.1 and the system always reboot automatically. I can not enter the system.

Now I have updated the linux kernel version 3.7.0. Download the linux kernel 3.7.0 and compile it, install it. The system can reboot successfully. However, I can not create the virtual machine successfully. Xenbus connect timeout, kernel panic. The following is messages that boot process:

netfront: Initialising virtual ethernet driver.

netfront: device eth0 has copying receive path.

Loading xenblk.ko module

Registering block device major 202

XENBUS: Timeout connecting to device: device/vbd/51712 (state 3)

no fstab.sys, mounting internal defaults

setuproot: error mounting /proc: No such file or directory

Switching to new root and running init.

unmounting old /dev

unmounting old /sys

switchroot: mount failed: No such file or directory

Kernel panic - not syncing: Attempted to kill init!

Anybody can give me some advice about the problem?
