Thread-topic: Bring up problem

 

I am hoping I can get a little light she on a problem I am having trying to bring up a guest domain.

I suspect that the problem is in my supplied file system

 

First the environment.

 

VT enabled dual core EM64T processor,

Asus Mb (I can get the exact chipset infor if relevant)

2 Gig of DRAM

SATA drives.

 

I have build and booted the domain 0 using 3.0.2-2 version of xen.  This seems ok. 

I have to change the PIIX_ATA to module support, but that was about it.

 

Xm list shows:

 

[root@localhost xen]# xm list

Name                              ID Mem(MiB) VCPUs State  Time(s)

Domain-0                           0     1019     2 r-----    44.6

 

Which is ok.

 

I have created a loop back file system on my /dev/sdd4.

If I mount /dev/sdd4 I can see a flat file of the correct size.  If I mount this in loopback mode, I can see the contents properly.

 

[root@localhost xen]# ls /remote

lost+found  vmdisk1

[root@localhost xen]# df

Filesystem           1K-blocks      Used Available Use% Mounted on

/dev/sdd2             14200032   9206208   4260860  69% /

/dev/sdd1               287782     32932    239992  13% /boot

/dev/shm                521728         0    521728   0% /dev/shm

/dev/sdd4             96210608   8961780  82282736  10% /remote

[root@localhost xen]# mount -o loop /remote/vmdisk1 /mnt/loop

[root@localhost xen]# ls /mount/loop

ls: /mount/loop: No such file or directory

[root@localhost xen]# ls /mnt/loop

bin  dev  etc  home  lib  lost+found  proc  root  sbin  sys  tmp  usr  var

[root@localhost xen]#

 

But when I try to start something up, I get the following:

 

(other stuff snipped)

Red Hat nash version 4.2.15 starting

Mounted /proc filesystem

Mounting sysfs

Creating /dev

Starting udev

Loading libata.ko module

Loading ata_piix.ko module

Loading jbd.ko module

Loading ext3.ko module

Loading aacraid.ko module

Adaptec aacraid driver (1.1-4 May 15 2006 08:33:35)

Creating root device

Mounting root filesystem

kjournald starting.  Commit interval 5 seconds

EXT3-fs: mounted filesystem with ordered data mode.

Switching to new root

unmounting old /proc

unmounting old /sys

exec of init (/sbin/init) failed!!!: 2

Kernel panic - not syncing: Attempted to kill init!

 

This looks to me like my file system is not “ok”.

 

BTW:  My simple config file is:

 

[root@localhost xen]# cat mach1

kernel = '/boot/vmlinuz-2.6.16-xen'

ramdisk = '/boot/initrd-2.6.16-xen.img'

disk = ['file:/remote/vmdisk1,sdd4,w']

root = '/dev/sdd4 ro'

memory = 512

 

any suggestions here?

 

Thanks

 

Gord
