I wasn't able to see any of the vlan nics in the output of the
getVdsStats. Perhaps you took that output in a different point of time
when the network was working properly, without configuring the vlan on
the host?
Once you'll be capable to connect to the host when the error appears in
the event log, please provide also the output of the getVdsCaps.
