The issue seams to be in node: the latest engine build
requires pc-i440fx-rhel7.2.0 which comes with qemu 2.3 while probably node
is still built from centos 7.1 with an older qemu.
For standard el7 host we are releasing it in the oVirt repo (
http://resources.ovirt.org/pub/ovirt-3.6-pre/rpm/el7/x86_64/qemu-kvm-ev-2.3.0-29.1.el7.x86_64.rpm
) but it seams that we didn't included it in node.

Please wait for a new build of node with that.
If you are in hurry you can also try to manually fix on your hosts:

$ remount / re-write
$ cd /tmp
$ wget all the qemu 2.3 rpm-files from
http://resources.ovirt.org/pub/ovirt-3.6-pre/rpm/el7/x86_64/ (there is no
yum on node)
$ rpm … to install/update the involved rpms
