I'm trying to locate more information about the Xen problem with
linux-image-2.6.24-16-xen. The bug causes a failure of bridging between
Dom0 and DomU, as documented in :
What are the chances of seeing a new DomU kernel before hardy release?
I don't think that it is likely due to the kernel freeze. I am hopping that maybe shortly after the release, we can at least get a working lppa for it. Maybe Chuck Short would be willing to host it?
Upstream support in Linux is coming along pretty well. It was just bad timing that this bug cropped up for the hardy release. I still wonder if there is a chance for fixes to get in for 8.04.1 (Idea: take the latest xennet driver code and port it to the hardy kernel)?*
Going forward, Hardy+1 should be able to take advantage of the work Red Hat has been doing getting support into mainline.
I hope that as the kernel team gets some time they can give us there opinions on these topics. There seem to be many that would like to help.
Hardy is a big step forward, it was just a difficult release period to support Xen, even Fedora 9 didn't release a dom0 kernel. Xen from source should work well for most people that need current Xen support. Going forward the future looks brighter for Xen support within the distros.

Todd
Thanks in advance,

Hirano's patch, is very small and looks easy to read. Users that have
tries Hiram's tiny patch have reported that domUs are fixed without
affecting dom0s negatively.
His patch is at:
http://launchpadlibrarian.net/13564638/004-xen-netfront-fix.patch
Found attached to this bug:

"HIRANO Takahito"
Xen networking on Hardy
Hello Tim and Subscribers,
I posted a patch to Bug #218126, and Chunk reformatted the patch,
which was committed:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/218126
However, Chunk's patch lacks an important line, which exists in my
original patch.
This difference causes BUG() in some environments.
with my original patch:
http://launchpadlibrarian.net/13564638/004-xen-netfront-fix.patch
I re-created the patch against the current hardy tree.
http://launchpadlibrarian.net/14048582/0001-UBUNTU-Fix-incomplete-commit-294d61f7b574d2909aec60.patch
Could you apply this patch?

Hi,
The patch was committed once, but seems to be reverted:
http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-hardy.git;a=commit;h=272e9bd390693017174eb6dd3e03e 955e4d5df81
What happened?
Thanks,

It was a side effect of the -security merge. I've already talked to Ben
about it, and I'll restore the commit before the SRU upload.
The DVB revert has the same problem.
