Thank you for the information!
And yes, I am trying to boot a 2.6 kernel and I am also using the
vmlinuz-2.6*xenU in the config file (it was a typo in my last email)
Actually, I was playing with it for a while and could partially boot the
guest OS.
The exact error I am getting is: Could not find LABLE=/ and boots in the
"repair filesystem" mode.
The guest OS could talk with the outside world but `xm list` command shows
state as -b--- (blocked) for the domain I am trying to boot.
I didn't check the /etc/fstab file, could that be the problem or is it
because I am not specifying something properly in the config file?
Lastly, if you could give me a link to your modified xen-U kernels it would
be great.
Again thank you for ur feedback.

Amitabh

Hi,
I am trying to boot a guest OS (SuSE 2.6 kernel) on Xen. But, it is giving
me boot errors.
The steps I followed:
1) Created a raw diskFile with ext3 filesystem
2) Copied /{root,etc,dev,var,usr,bin,sbin,lib} from my SuSE 2.6
installation on to the diskFile
I would suggest you copy everything from a non-running linux installation.
You could also use a running machine as starting point, but you should
exclude these files :
/proc/*
/var/log/*/*
/var/run/*/*
/var/run/*.pid
/var/tmp/*
/var/lock/*/*
/dev/mapper/*
/tmp/*
/sys/*
/mnt/*/*
Note that you NEED /proc, but you don't need anything under it.
Then you have to modify /etc/fstab accordingly, and use /dev/sda1 as root.
3) Created a config file as:
Important parameters are as follows:
kernel = "/boot/vmlinuz-2.4.27-xenU"
disk = ['file:FullPathToTheDiskFile,sda1,w']
root = "/dev/sda1"
(other parameters skipped)
4) Booted-up the new Domain
It is giving some-errors like /lib/modules/2.6.9-xenU/modules.dep not
found. And boots up in the
You need to copy /lib/modules/2.6.9-xenU/ from the physical server (the
server you're running xen's
"make install" from) to the virtual server. Alternatively, recompile the
xen-U kernel
to disable modules support and you can ignore the error completely.
If you're running athlon-xp or P4/Xeon, I can share my xen-U kernel (or the
.config), with modules disabled,
optimized for those platform.
Can anyone tell me what exact changes do i need to make to the SuSE 2.6
kernel to be able to boot it as a new Domain?
Are you using 2.4 or 2.6? Your xen config file says 2.4.
I understand that the machine dependent code has to be changed with new
code provided by Xen....but I could not find a place where it
says........."These are the exacts steps you need to follow for porting of
Guest OS in a Domain"
Because it's not there yet :)
