[Xen-users] Unable to start domain based on ubuntu filesystem

[Ricardo <djrico@xxxxxxx>]

I recently installed Ubuntu 4.05 Hoary on a separate partition (JFS
filesystem), installed Xen on it, and then dd'ed the filesystem into a
file (ubuntu.img).  I also created the requisite config file, which I
have included in this e-mail.  When I try to run it using xm create -c
ubuntu, I get the following error:

IP-Config: Incomplete network configuration information.
jfs_mount: Mount Failure: File System Dirty.           
Mount JFS Failure: -22                     
Kernel panic - not syncing: VFS: Unable to mount root fs on
unknown-block(3,1)
                                                                             

************ REMOTE CONSOLE EXITED *****************

Does anyone have a clue as to what's going on here and how I can fix it?

# Configuration file for Ubuntu 4.05 Hoary
#
#----------------------------------------------------------------------------
# Kernel image file.
kernel = "/boot/vmlinuz-2.6.11-xenU"

# Optional ramdisk.
#ramdisk = "/boot/initrd.gz"

# The domain build function. Default is 'linux'.
builder='linux'

# Initial memory allocation (in megabytes) for the new domain.
memory = 96

# A name for your domain. All domains must have different names.
name = "ubuntu"

# Which CPU to start domain on? 
cpu = -1   # leave to Xen to pick

#----------------------------------------------------------------------------
# Define network interfaces.

# Number of network interfaces. Default is 1.
nics=1

# Optionally define mac and/or bridge for the network interfaces.
# Random MACs are assigned if not given.
vif = [ 'mac=00:09:6B:E0:57:8A, bridge=xen-br0' ]

#----------------------------------------------------------------------------
# Define the disk devices you want the domain to have access to, and
# what you want them accessible as.
# Each disk entry is of the form phy:UNAME,DEV,MODE
# where UNAME is the device, DEV is the device name the domain will see,
# and MODE is r for read-only, w for read-write.

disk = [ 'file:/etc/xen/images/ubuntu.img,hda1,w' ]

#----------------------------------------------------------------------------
# Set the kernel command line for the new domain.
# You only need to define the IP parameters and hostname if the domain's
# IP config doesn't, e.g. in ifcfg-eth0 or via DHCP.
# You can use 'extra' to set the runlevel and custom environment
# variables used by custom rc scripts (e.g. VMID=, usr= ).

# Set if you want dhcp to allocate the IP address.
dhcp="dhcp"
# Set netmask.
#netmask=
# Set default gateway.
#gateway=
# Set the hostname.
#hostname= "vm%d" % vmid

# Set root device.
root = "/dev/hda1"

# Root device for nfs.
#root = "/dev/nfs"
# The nfs server.
#nfs_server = '169.254.1.0'  
# Root directory on the nfs server.
#nfs_root   = '/full/path/to/root/directory'

# Sets runlevel 4.
extra = "4"

#----------------------------------------------------------------------------
# Set according to whether you want the domain restarted when it exits.
# The default is 'onreboot', which restarts the domain when it shuts down
# with exit code reboot.
# Other values are 'always', and 'never'.

restart = 'never'
