I have basic skills in debian, and gentoo. A bit rusty on the
rpm-based distros. Totally unfamiliar with *BSD. Total newbie in XEN
So, given this list is bound to be a bit biased, : why would I pick
gentoo for dom0, and what version of XEN would I use ?
Picking gentoo for dom0 is probably the same question as "why would I
use gentoo instead of other linux distribution". Me personally have
very good experience in running xen dom0 machines on gentoo. If you
separate your dom0 machine and the services are in domUs, then the
dom0 is very small, clean and easy to maintain (for years). Ask on the
debian list and I'm sure they will answer the same way so it's your
choice ;)
If it's a new server you may try the new 4.5 release. I don't know how
stable it is, I just started my first VM on 4.5 today, but I'm running
4.3 in production and 4.4 in pre-production. Since you don't need to
migrate in production, it's not a problem I believe.
Arye you using the 4.5 ebuilds from portage ?

Debian Jessie tells me (as an example):
# apt-cache search xen-hyp
xen-hypervisor-4.4-amd64 - Xen Hypervisor on AMD64
xen-hypervisor-4.0-amd64 - The Xen Hypervisor on AMD64
xen-hypervisor-4.0-i386 - The Xen Hypervisor on i386
xen-hypervisor-4.1-amd64 - Xen Hypervisor on AMD64
xen-hypervisor-4.1-i386 - Xen Hypervisor on i386
# apt-cache policy xen-hypervisor-4.4-amd64

My gentoo box tells me:

So it seems that if I decide xen 4.5, gentoo might be less hassle ?
Yes, 4.5 from portage. Only if you use EFI you need a patch that is not
in portage at the moment: https://bugs.gentoo.org/show_bug.cgi?id=534570
If you want debian, version 4.4 will be also great and they will supply
the packages soon I believe. I think the version (4.3, 4.4 or 4.5) is
not the crucial factor, each of them will work, only if you need the
newer features.
