Why can't 4.4 be LTS for C6? as it's the last build with XM. Any XSA patches should not be hard to backport. and maybe the optional xen4.6 for C6.
The Xen Project does large of testing of Xen before updates and releases; and I do a basic amount of smoke-testing before sending an update. But I don't really have the resources or the ability to do the kind of extensive testing which would allow me to recommend automatically pulling updates without testing them first, nor do I envision any SIG ever having that amount of resource. If that's the kind of support you want, you might want to consider paying for either XenServer or SLES. :-)
