Subject: Status of Xen in vanilla?

Hi!

I'm wondering about the status of Xen support in the vanilla kernel.
I know that DomU support is inside the kernel an evolving, but I did
not find an up-to-date hint about the status of Dom0 support.

A while ago I read that it should be included in 2.6.28, but I do not
find any current pointer about the status of this.

Thanks for hacking on it!

.28 was a bit optimistic; .29 seems reasonable. The current dom0 kernel
patches can boot up to a fully functional dom0 usersmode, and you can
start xend to see that domain 0 is running. I *think* in theory you can
create a deviceless domain, but I haven't tried it. I'm currently
working on blktap support.

I really need to put together a proper status update. Now that dom0
usermode is working, its a much better base for other people start
contributing.

This reminded me of updating http://wiki.xensource.com/xenwiki/XenParavirtOps

Now it says "Features added in 2.6.27".

Maybe you can go through the page, and update/add missing stuff..
