[Xen-users] Question ttylinux

[田冠华 <tianguanhua@xxxxxxxxxx>]

Hi,

I have got xen compiled and installed properly.Domain 0 is created on the Xen port of Linux-2.6.11.10.But I am unable to boot the host domains.

This is what one of my XenU config file contains

[root@xion /]# cat /etc/xen/ttylinux
kernel = "/boot/vmlinuz-2.6.11.10-xenU"
memory = 64
name = "ttylinux"
nics = 1
vif = [ 'mac=bb:00:00:00:00:11, bridge=xen-br0' ]
disk = [ 'file:/mnt/xenfs/ttylinux-xen,hda3,w' ]
ip = "10.1.10.20"
hostname = "ttylinux"
root = "/dev/hda3 ro"

/dev/hda3 maps to / on where my Xen Domain 0 is running.

This is the error in detail I get after trying to boot Xen U.

[root@xion /]# xm create -c /etc/xen/ttylinux
Using config file "/etc/xen/ttylinux".

The superblock could not be read or does not describe a correct ext2
filesystem.  If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
    e2fsck -b 8193 <device>

WARNING: Errors found while checking root filesystem.
You can login as root now, the system will reboot after logout.

Give root password for system maintenance
(or type Control-D for normal startup):
