RE: [Xen-users] Xen 3.4.2 on kernel 2.6.32.8 on Lenny

["Robbie A. Garrett" <RGarrett@xxxxxxxxxxxxxx>]

Hello,
perhaps I missed something I see no xen options in menuconfig when i pull down 
the kernel from xen/master

The command i did was 
git clone git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git 
xen/master  which brought down a directory of xen/master.

When I run make  menuconfig it does show 2.6.31.6 as the kernel version which i 
think is correct..  but again I see no xen options.

Upstream Linux 2.6.32.8 kernel from kernel.org doesn't support
running as Xen dom0. It only supports running as Xen domU (guest).

You need to get the 2.6.31.6 kernel from Jeremy's git tree (xen/master branch),
it has dom0 support included.

xen/next branch has 2.6.32 kernel.
