Hi

Im trying to get DSL(damm small linux) to run in Xen, DSL is a small live-iso with linux.

I have made a simple configuration file, se below:

 

  <configuration file>

  kernel = "/boot/vmlinuz-xen"

  memory = 64

  name = 'dsl'

  disk = ['file:/tmp/dsl-3.3.iso,sda2,w']

  root = "/dev/sda2 ro"

  <configuration file>

 

 

The filesystem on the Xen server is shown below.

 

  da10:/etc/xen/vm # df -h

  Filesystem            Size  Used Avail Use% Mounted on

  /dev/sda2             9.6G  4.2G  5.4G  45% /

  udev                  232M  164K  231M   1% /dev

 

And the DSL-iso is laying in /tmp(sda2)

 

  da10:/etc/xen/vm # ls -l /tmp/dsl-3.3.iso

  -rw-r--r-- 1 root root 52056064 May  8  2007 /tmp/dsl-3.3.iso

 

Ill then starts up the domain with:

 

  xm create /etc/xen/vm/dsl -c

 

The domain starts up, but I get a kernel panic from the dsl-domain

 

  VFS: Cannot open root device "sda2" or unknown-block(0,0)

  Please append a correct "root=" boot option

  Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

 

Can anyone see what I have done wrong?

hello,

It works fine with a few changes.
You want to use the qemu device model.
Your disk line doesn't point to the ISO correctly.

With the config below I can see and mount most of my partitions in DSL.
Note the "boot" points to the CDROM.

tlviewer@KN9ULTRA:~> cat /etc/xen/vm/dslvm
------------------------------ dslvm config ---------------------
disk = [ 'file:/windows/D/download/dsl-3.3.iso,hdc:cdrom,r' , 'phy:/dev/sda,hda,w' ]
memory = 512
vcpus = 1
cpus = ""
builder =
 'hvm'
device_model = '/usr/lib/xen/bin/qemu-dm'
kernel = '/usr/lib/xen/boot/hvmloader'
name = 'dslvm'
vif = [ 'ip="192.168.1.108",type=ioemu,mac=00:16:3e:21:c4:f8,bridge=xenbr0' ]
stdvga = 0
netmask = "255.255.255.0"
gateway = "192.168.1.1"
hostname = "xen"
#dhcp = "dhcp"
vncdisplay = 1
#vif-script = vif-bridge
sdl = 1
apic= 1
acpi = 1
pae = 1
vnc = 0
#vif-script=vif-nat
#dhcp=yes
serial = "pty"
vncviewer = 0
ne2000 = 0
localtime = 1



boot = "dca"
--------------------------- end config -------------------


regards,
Mark
