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.
