How did you configure that vlan address on each of your hosts? Via the
Setup Host Network dialog?

Quite often, we have a race where networks configured with dhcp do not
report their acquired ip address to Engine. This is to be solved by

    Bug 1240719 - [RFE] - Send an events to engine upon network changes

but until then - by clicking the "Refresh Capabilities" button, moving
the host to maintenance and back, or stopping-waiting-restarting Vdsm.

If "Refresh Capabilities" solves your issue as well, you're seeing the
problem I'm referring to.
