Re: [Xen-devel] domU guest for xcp 0.1.1

[Ritu kaur <ritu.kaur.us@xxxxxxxxx>]

I tried another thing. After compilation,  I did "make modules_install" in xcp ddk in order to use following command

mkinitrd -f ./initrd-2.6.32.img 2.6.32

I get following errors...

modinfo: could not find module ide-disk
No module ide-disk found for kernel 2.6.32, aborting

My boot disk is ide and looking into .config didn't give me any ideas as to what has to be enabled. 

Thanks

Thanks Pasi. I had used following command to regenerate initrd image in xcp ddk

mkinitrd -f ./initrd-2.6.32.img  2.6.27.42-0.1.1.xs0.1.1.737.1065xen

it doesn't work either. While booting screen goes blank immediately after I see

...
 Booting:MBI=0x00010120, entry=0x00100000
 

and next thing I see is BIOS setup, so not sure connecting serial cable will reveal anything more. Inputs appreciated.

Thanks

You need to re-generate the dom0 kernel initrd to match your kernel.
You cannot use the default xcp initrd image.

Please provide the full serial console boot log so we can troubleshoot it:
