Hello,
I have a newly created datacenter in 3.2.1 with f18 host where
ovirtmgmt is set as vlan.
host is installed but after some minutes I get this messages:

Host management02 moved to Non-Operational state because interfaces
'em1.311' are down but are needed by networks 'ovirtmgmt' in the
current cluster


from an operating system point of view it seems that all is ok on the host

what can be the cause?
what is the check that runs and move the host to non-operational?
Thanks
