Hi, I'd like to enquire about the possibility of the patches filed in #473645 being applied to the Debian kernel packages.
The bug report was closed and had the patch tag removed. However I think
this was a misunderstanding since one the patches ("v2.08") directly
addresses the issue which Bastian cited, he said:
Because of several shortcommings in the maintainer scripts and
the image loader, this currently needs an extra image, which is
built.
The v2.08 patch eliminates the need special image in domU by allowing
the image loader to load the bzImage file directly. Together with the
"enable-xen" patch and the Xen patches in #474509 it is possible to boot
any of the kernels from the regular (i.e. non-xen) packages in a Xen
guest domain (subject to compatibility with the hypervisor).
The v2.08 patch has been applied upstream [0,1&2] and will be in the
2.6.26-rc1. Is there any reason not to apply a backport to the 2.6.25
kernel? Having these patches applied to the kernel would be a big step
forward in my project of making the Debian installer fully
usable/compatible with paravirtualised guests as originally discussed at
[3].
I'm not sure what the shortcomings of the maintainer scripts that
Bastian also refers too are since the packages work fine for me in domU
(note that dom0 is still a special case). There is a bug in update-grub
WRT handing pvops kernels which I am investigating separately. If there
are any other known issues me I'm more than happy to work on resolving
them if they are brought to my attention.
The third patch in the ticket
xen-modules-autoprobing-support-for-frontend-drivers.patch is queued up
in the x86 tree but isn't in mainline yet[4]. Compared with the other
patches it's just a "nice to have" patch since it stops d-i from needing
to prompt separately for the Xen frontend drivers to find network and
disks.
Thanks,
Ian.
