If network is out of sync, check in the UI the network settings for the host.Usually all network changes should be done in the UI /or via the API/.

I wont change legacy to ovs switch mode, using instruction below: - Install first host and VM using "hosted-engine --deploy" - In the Engine UI, change Cluster switch type from Legacy to OVS - Shutdown the engine VM and stop vdsmd on the host. - Manually change the switch type to ovs in /var/lib/vdsm/persistence/netconf/nets/ovirtmgmt - Restart the host After this changing my hosted engine don't wont start, it says i have a problem with vnet interface, i don't know virtmanager or i don't know vnetuser. When i had return back settings from ovs to legacy mode, hosted engine start without any problem When i had change file  /var/lib/vdsm/persistence/netconf/nets/ovirtmgmt on hosts without hosted engine, they are change network mode and start working as ovs switch mode but they say network out of sync. I tryed to migrate hosted engine from host with legacy switch to host with ovs switch hosted engine don't wont migrate.
