There will be no *official* support for Xen dom0 in RHEL6 and it's
derivatives. That said, there is already work under way to get dom0
support into RHEL6. I'm personally working on a tutorial now, and I know
a few people are working on the kernel.
Though, right now, the focus seems to be restoring official dom0 support
into Fedora 15, so it will be a little slow getting into RHEL6.
I expect that Michael Young's Fedora 12 kernel will recompile fairly
easily onto RHEL6 as both are 2.6.32 based. I hope to test that tonight
or tomorrow. As for comparing KVM to Xen, I am also working on some
benchmarks as I truly don't know which is faster. What I can say, at
this point, is that the differences are structural more than anything.
Personally, I like the idea of have a minimal "host OS" as seen in Xen.
Though I don't have any hard reasons backing that up yet.
Once I finish my benchmarks, I will post them to the CentOS-virt mailing
list. I'm still hoping to have numbers by the end of this weekend,
assuming I don't run into too many problems getting Xen dom0 running.
