the xen-source on gentoo
I want to install the xen on gentoo . But i find the xen-source version is
2.6.38 . So i don't want to use it. Can i use my gentoo-source 3.2.12 with
a patch?

"Linux 3.0 (and later) can run as guest (domU) and as host (dom0). All
necessary backends (and frontends) are in the upstream kernel." [1]

Most of the Xen found its way into mainline by the 3.0.x series.
AFAIK, most of the bugs have been worked out by now; you should be
able to use gentoo-sources 3.2.12 without any additional Xen patches.

The "Xen" config will not be visible until you configure other settings in
the "Processor" page.

There are several; rather than listing them all here, please see the
following page by yours truly:

I forgot to stress: The page is kind of out-of-date, e.g., comments about
staying away from 3.0. The menuconfig options might also get shuffled
around, but the gist of it is still the same: There are options you need to
set in a certain way before XEN option becomes visible.

Please do not top-post.

Try turning on "Enable paravirtualization code".
