Hello,

I would take Debian Squeeze. At the end it is a question of which you 
like more. The compilation of Xen 4.2 is very simple and discribed in 
the Wiki. You can do this in a chroot to prevent installing all needed 
packages in the production system itself. The deb make target is very 
useful this will create a deb package of the Xen distribution so you can 
simple install and uninstall the core components very easy, you just 
will need to install a few additional libs over apt/dpkg like libjpeg 
because they are needed for the QEmu Backend but not a dependency of the 
created deb package. Make sure that you made the in the wiki mentioned 
configfix that everything is installed on the correct place 
(--install-layout=deb)
For nativ Dom0 support in the kernel which is not given in the normal 
squeeze Repos (2.6.32 kernel) you can use 3.2.0 from the backports repo 
(http://backports.debian.org).
Best Regards
