[ovirt-users] Ovirt adding routes

[Edward Haas]

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.
