of course it doesn't.. we still didn't merge 
http://gerrit.ovirt.org/#/c/37384/ . but with libvirt >1.2.3 you are 
able to hack dsaversion to report also 3.6 and use it.
we still struggling to define the approach to go with 
http://gerrit.ovirt.org/#/c/37598/
one of those patches need to get in to allow adding any host to 3.6 
cluster without additional hack
