In RHV 4.1, users can now set the default route of a host. RHV sets the management network as each host's default route. Some customers prefer the management network to be a local non-routed network, and that another network serves as a default route. 1. In the Manager, open a console and add the custom property. # engine-config -s UserDefinedNetworkCustomProperties='default_route=^(true|false)$' # servicectl restart ovirt-engine 2. On each host: 2.1 Set the property to False on the management (ovirtmgmt|rhevm) network 2.2 Set the property to True on the desired new default route network 2.3 Set a next-hop IP address (Gateway) in the new default route network 3. Apply configurations Two important notes that must be added to the docs: * This configuration is PER HOST, and needs to be done on each host. * If the gateway for the new default route network is not set, it will be IGNORED. Leaving the gateway blank will NOT set device based route (such as for proxy-arp scenarios).
