  Tne answer is NO. Any vanilla kernel (> 2.6.27) itself allows only to enable PV Guest (paravirtual) mode, but not Xen Dom0 Support. Mainline Linux
doesn't  contain Xen Dom0 Support merged. You have to work on it on your
own.
  I've sent you two links in the very first message. View second one - patching 2.6.30.1 via Andrew's Lyon rebase patch set :-

  http://lxer.com/module/newswire/view/122758/index.html

The procedure above will build 2.6.30.1 xenified kernel, i.e. will implement
Xen Privelege (Dom0) Domain Support. My Config.mk is attached.

Boris.

P.S. You may want to build another type of kernel, enabling Xen Dom0 Support. It's pvops enabled kernel via Jereme Fitzhardinge Git Repo.
Then view :-

Didn't reboot properly. Maybe I'm misunderstanding the kernel part, using a vanilla 2.6.30 with all of the xen stuff enabled should work, correct?

In other words, to build Xen 3.4.1 you have to understand what Changeset 19594 does. To build Xen 3.4.0 you also have to back port CS 19668 to be able detect  properly udev 141. I am not sure what version of Xen you've tried to build on Jaunty.

Set in Config.mk
PYTHON = python
PYTHON_PREFIX_ARG =

Tuning Config.mk results Xen packages to be placed into /usr/local/lib/python2.6/dist-packages due to Changeset 19594 in xen-3.4-testing.hg. Otherwise, Xen packages would go to /usr/lib/python2.6/site-packages, which is not default location for python 2.6 on Ubuntu 9.04 ( vs F11 ). Thus you won’t be able to start xend in Dom0. Same thing happens when building Xen Unstable on Ubuntu 9.04 Server.

If you need more details for pvops kernel :-

I decided to give this a try as I'm out of fun things to do, but I'm at my wits end on this one. I have compiled a 2.6.30 kernel with Xen enabled, and compiled and installed Xen 3.4 from source. 2 major problems I have noticed is that after configuring grub per the documentation I've found, it either reboots my PC after grub loads the config, or stays at a black screen. The second problem is the error below:
 
Traceback (most recent call last):
  File "/usr/sbin/xm", line 8, in <module>
    from xen.xm import main
ImportError: No module named xen.xm
