[ovirt-users] Failed to configure management network on the host. - oVirt in a KVM

Hi guys, I'm trying oVirt in a KVM and I get this: ... [ INFO  ] The host has been set in non_operational status, deployment errors:   code 505: Host c8ovirt1.private.road installation failed. Failed to configure management network on the host.,    code 519: Host c8ovirt1.private.road does not comply with the cluster road networks, the following networks are missing on host: 'ovirtmgmt',    code 1120: Failed to configure management network on host c8ovirt1.private.road due to setup networks failure.,    code 9000: Failed to verify Power Management configuration for Host c8ovirt1.private.road., code 10802: VDSM c8ovirt1.private.road command HostSetupNetworksVDS failed: Internal JSON-RPC error: {'reason': 'Failed to find interface to with route table ID 254 to store route rules'}, ... How much of a worry is it and how to fix such KVM vm so oVirt would be happy? many thanks, L.
