Xen users - Dec 2007 - Installing ubuntu as domU on Suse SLES dom0

Hi,

I''m looking for pointers to install an ubuntu 6 LTS domU on my suse
enterprise 10 dom0 running xen 3.1

What''s the easiest way to do this? Can I boot an install CD in /dev/dvd

I have installed ubuntu as a test locally. I thought perhaps I could
just copy the partition for my working install here, so I used dd to
cop the partition and moved it to the Suse box. I then used dd to
extract the partition copy to a new LVM drive /dev/system/ubuntu_lts

I''m not sure how to get this to be bootable though. If i try a config
file like this:

name="ubuntu"
memory=512
vcpus=2
on_crash="destroy"
on_poweroff="destroy"
on_reboot="destroy"
localtime=0
kernel="/ubuntu/vmlinuz-xenpae"
disk=[ ''phy:/dev/system/ubuntu_lts,hda,w'']
root = ''/dev/hda''
vif=[ ''mac=00:16:3e:6a:b4:43'', ]
nographic=1

I just get:

VFS: Cannot open root device "hda" or unknown-block(0,0)
Please append a correct "root=" boot option; here are the available
partitions:
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

Does anyone one the list have any suggestions?

Thanks,

Russell

Hello, 


Try to specify no only kernel, but initrd (ramdisk) also.
You can do it with a line like this:

ramdisk="/ubuntu/initrd.img-xenpae"

(of course, you must specify correct name of ramdisk)


Also, make sure that you can mount /dev/system/ubuntu_lts
in the dom0 (to be sure, that you haven''t damaged it during
transmition).


Regarding your question 
"""
Can I boot an install CD in /dev/dvd?
"""

yes, you can, but only if you have an HVM-capable system.
(if your system is not HVM capable you may also boot cd, 
and install system from it, but the CD must be modified to
be able to run in the PV mode. I suppose, that this is not 
a good option for you for this time.)
