Hi Alan,

The oVirt host agent (VDSM) has a multi-gateway/sourceroute feature which allows gateways to be specified per network, in addition to the host level routes.

By default and depending on which version you use, only the ovirtmgmt (management) network defines the host default route but all networks (including ovirtmgmt) have a gateway definition which is set on a per network base.

The way network based routes are defined is using different routing tables and rules.

For more information, please see the feature page: http://www.ovirt.org/develop/release-management/features/network/multiple-gateways

It should not block or interfere with your traffic, unless you are doing something unexpected, like having the default that collides the the one defined using ovirtmgmt network.

Thanks,

Edy.

Hi,

When installing an ovirt host I got these routes automatically added

default dev ovirtmgmt table 2886865805 scope link
172.18.19.128/26 via 172.18.19.141 dev ovirtmgmt table 2886865805

What is their intended purpose? It seems to be stopping packets from being correctly routed to the local gateway.

Thanks,

Alan
