My opinion that only way to go is Debian.
2.6.18 stretch more then most people could ever imagine.

You could use 'debootstrap' for .deb based distros or was it 'rpmstrap' or 
something to build .rpm based distros.
And if your hardware support you can install much more with HVM.
(and maybe after install move it to paravirt environment...)

That's true.
'Best Setup' depends so much what you are tying to accomplish.

This is something what i can't understunt.
What's the point to get support for DomU if you can't run Dom0? :)

Im just asking cos I have Quad-Core with ICH9 based motherboard and that 
setup is newer going to work stable with 2.6.18....
My life would be so much easier if Xen could be ported to mainline and 
would be 'only way' to run Linux :)
My desktop setup now has 2.6.18-xen and all nice 3D-shit including Compiz 
and it's working like charm :)
So I can 'boot up' pretty much anykind of testing environment i ever 
wanted and that's is pretty much all I need at home and work.
