Xen project Mailing List

Well... If the Ubuntu repo does not provide a good Xen kernel, maybe I should build my own, too.

How would I go about doing this?

Do I still use the xen-tools from the repo, or do I need to compile those too?

How should I do this? Is there a how-to?

(Keep in mind I've never built a kernel before....)

Thank you...

Hi, I also have Ubuntu Gutsy 7.10 and having lots of problems with its xen version and 2.6.22-14-xen kernel, including HVM domains hanging at boot. I don't suggest it for use. Unfortunately, the Ubuntu development guys look so busy that they can't also close the bugs that I've submitted (at least an explanation) 1 month ago.

Br, Emre
