Subject [jira] [Commented] (CLOUDSTACK-6505) bridge gets reset for cluster level OVS network.
Date Fri, 25 Apr 2014 10:14:15 GMT


ASF subversion and git services commented on CLOUDSTACK-6505:

Commit 8e4391bff310bd3583cf81fe0260e8349d05f82f in cloudstack's branch refs/heads/master from
[;h=8e4391b ]

CLOUDSTACK-6505: XenServer bridge for the OVS tunnel network gets reset
on the hosts in the xenserver cluster

this fix ensures that brige is created only once so that openflow rules
configured on the bridge are not lost.

>     CLOUDSTACK-6356: OVS: tunnel networks does not work across the XenServer
>     clusers
> To make internal network work across the cluster, above fix introduced logic to plug/un-plug
VIF in dom0 connected to OVS internal nework. this logic would ensure there is a bridge created
on each host. But this logic should execute only once to created bridge. Currently its executing
multiple times resulting in bridge to be recreated and hence loosing all the open flow rules.
> Fix for this bug should ensure we only create bridge once on each for the OVS tunnel
