Multiple Gateways: Upgrade VDSM to 3.3 must reconfigure networking on host
Last modified: 2013-10-16 02:39:23 EDT
Description of problem:
From a multiple gateways feature perspective: Adding a brand new host to oVirt works properly. The ovirtmgmt bridge will be created and source routing will be configured for the bridge. Any new network attached to other nics will get source routing configured as well.
However: Upgrading an existing host to VDSM 3.3 currently does not configure source routing to existing VDSM controlled interfaces. So if the host already has ovirtmgmt configured source routing won't be configured for it, and attaching a new network will break connectivity to the host if the new network has a gateway defined.
Version-Release number of selected component (if applicable):
Upgrade to VDSM for oVirt 3.3
Steps to Reproduce:
1. Upgrade an existing host to VDSM 3.3
2. Attached a new network with a gateway defined
ovirtmgmt bridge has no source routing configured and the ovirtmgmt default route has been replaced by the new interface's default route = Lost connectivity to the host
Keep connectivity to the host
No longer blocks oVirt 3.3 when https://bugzilla.redhat.com/show_bug.cgi?id=994523 is solved.
