Hi
I have been using pygrub for most of the needs. Was
trying out some stuff on SLES 10 SP1. It seems that it
does not have pygrub!!
On the other hand,they have domUloader.py which
requires bootargs="--entry=hda:/boot/vmlinuz...., path
to ramdisk.
It is quite strange to be asking for the path of
the kernel and the ramdisk to be supplied in the conf
file!!.
Am I missing something here ? PyGrub does not require
all these details.
For example :
on one of my images, the path is
/boot/initrd-2.6.16.29-0.11.smp.pae.gcc3.4.x86.i686.xen.domU.img
-- Also, the domUloader does gives error when there is
not partition. i.e. the image can be simply mounted by
using mount -o loop /file.disk /mount/point

fwding to xendevel for comments. Basically, I have some vm_templates with pygrub that work, but with domUloader for each image, one has to find out the kernel/ramdisk from domU and provide this in the vm config file. What is a good way to do this ? (scanning disks, partitions, mounting them, and then search for kernel. .. isnt this what the loader is supposed to do ?) I really hope I am missing something in the way to use domUloader. thanks /Jd --- jd <jdsw2002@yahoo.com> wrote:> Hi > I have been using pygrub for most of the needs. > Was > trying out some stuff on SLES 10 SP1.

Edit bootargs entry in domU config, providing kernel/ramdisk. If you don''t know the paths, use lomount to mount the image and poke around. 2. Use vm-install and select "I have a disk or disk image with an installed operating system" and let it create the config for you.> (scanning disks, partitions, mounting them, and then > search for kernel. .. isnt this what the loader is > supposed to do ?) >Yes :-). I would like to start using pygrub in SLES11. I was not with the project when domUloader was born but I think it was originally written to support Netware - which does not have grub. At the time, I''ve heard there were many problems getting pygrub to work on libreiserfs (reiser is default filesystem in SLES10) so domUloader was used for grub-based systems as well. If the default fs becomes ext3 (or something other than reiser) in SLES11 then that will be a great opportunity to switch to pygrup and reserve domUloader for reiser-based domU''s, Netware, and other ''grubless'' systems.

Thanks for the interesting background info. Would you know bit more about the domUloader not being able to mount unpartitioned disk ? If there is a patch available for SLES 10 SP1 ? I will definitely check out the vm-install and see if that can be used.

From my (admittedly minimal) testing of the new pygrub reiserfs implementation, it all worked fine regards john _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
