[gentoo-user] what about Xen finally?

[Mihamina (R12y) Rakotomandimby]

Hi,
I have a computer with a intel 4965 wireless chipset on which I want to 
run Xen and only use ebuilds.
So, I need a recent gentoo kernel (some 2.6.22 but I dont know which 
exactly). I really want to use only ebuilds.

The question would then be: What ebuild (from whose repository?) should 
I use?

I ask because the xen install on the wiki becomes messy and I feel lost 
reading it.
Anyway, some mentionned repos are out of date in there, it's a sign of 
old documentation.
I am volunteer to clean it up, but I need help in order to know what are 
the new informations.

Thank you in advance.

PS: I wish to use a 64 bit system if possible...

Think I'm missing something here. Xen is in, as masked ebuilds, but it's
there.

Xen-sources doesn't go as high as .22 yet in the portage tree. The
newest one is .20, but that should be okay for most people.

Xen actually made it in to the .23 mainline kernel, and should therefore
be seen in sys-kernel/gentoo-sources-2.6.23* (if you feel like waiting a
little longer). Otherwise, use xen-sources and the xen ebuilds.

Do you mean xen will be directly in the kernel, the way alsa is?
I did not see that great news on the Xen users ML.
Have you got any reference?

Thank you.

That's exactly what I meant :)

I got the news from kerneltrap.org[1], and the git commits are directly
viewable on git.kernel.org[2].

I would note, however, that it's just the domU(?), meaning you can build
Linux as a guest kernel. The dom0 stuff, however, which is required to
build a hypervisor, is *not* in mainline. Your link states that in a
comment, but I wanted to explicitly point it out.

To quote kernelnewbies:

"Xen

Part of Xen has been merged. The support included in 2.6.23 will allow
the kernel to boot in a paravirtualized environment under the Xen
hypervisor. But support for the hypervisor is not included - this is
only guest support, no dom0, no suspend/resume, no ballooning. It's
based in the paravirt_ops infrastructure."

I don't want anybody disappointed from the realization when they get to
the kernel configuration with 2.6.23 ;).
