If you want to use Xen's 2.6.18 kernel, you can do a "make help" on
the untarred xen source directory. It will show you how to do lots of

Alternatively, go to http://www.xen.org/products/xen_source.html,
download "Linux 2.6.18 with Xen 3.4.x support source tarball", and
configure it like a normal kernel (make menuconfig, make, etc.)

And there's newer kernels of course. See

If you just want to use Suse's kernel-xen, the obvious way would be to
run "zypper install kernel-xen".

I'm not sure. "make uninstall" MIGHT work, but I haven't tested it.
There was a warning on this list sometime ago that "make uninstall"
deletes stuff on /boot with "xen" name on it, whether it's installed
by the source or not. I don't know if it's still the case.

This is one of the reasons why I prefer using RHEL5 + Gitco. I can
simply do a "yum install" and "yum erase" :D
