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

[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

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
