Yes.

Correct.

There is README file in the root of xen source tree.  Read it to see how
to configure and build xen0 and xenU.

I am afraid you will have to stick to whatever kernel is used by
particular version of Xen.

Again, the README file contains all the commands required for
configuring and building of your kernels.

   for dom0:

   # make linux-2.6-xen0-config CONFIGMODE=menuconfig
    # make linux-2.6-xen0-build
    # make linux-2.6-xen0-install

 For domU, replace xen0 with xenU.
