Hi,

I'm new to Xen so please bear with my basic questions.

I use Debian Kernels with add-on patches applied to it. (Bootsplash, SKAS,
debianlogo, kdb, swsusp et cetera).

I want to try Xen too. I looked into Xen Source tarball which contains a
"mkbuildtree" shell script which adds xen tree to my patched kernel.

My questions:

1) If I patch my kernel with Xen, will I be compromising on any of the other
features that I've patched ? (Namely UML and swsusp. I use UML a lot)

2) So when I boot with a Xen kernel, the OS it boots into is dom0 which
simply is my normal OS. Right ?

3) If I'm correct about Question 2 then, "when only using dom0, does it add
any virtualization overhead to the host OS i.e. dom0 ? Or does it simply
function as a normal Linux Kernel with Xen features not being in use ? "

Thanks,
Ritesh
