Dag Sonstebo resolved CLOUDSTACK-525.
-------------------------------------
Resolution: Fixed
Fix Version/s: 4.5.0
Tested in CS4.5, two VRs come online as master and backup, failure of master
results in second VR becoming master.
Routing and functionality tested and works OK.
Overall - can't reproduce, old issue considered fixed.
> Cloudstack Redundant Virtual Router issues both MASTER.

> Key: CLOUDSTACK-525
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-525
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: Install and Setup, KVM, Management Server, Network
> Controller, Network Devices
> Affects Versions: 4.0.0
> Environment: Two servers with same hardware running Ubuntu 12.04 LTS.
> Reporter: Alex Mathiasen
> Assignee: Dag Sonstebo
> Priority: Critical
> Labels: RVR
> Fix For: 4.5.0
>
>
> Steps:
> - Two hosts added to cluster
> - Add network offering with RVR set,
> - Create instance using that network offering
> - Look at the state of both virtual routers on each host being MASTER
> Due to the state above, you will recieve errors with the following message:
> More than one redundant virtual router is in MASTER state! Router r-15-VM and
> router r-14-VM - Virtual router (name: r-15-VM, id: 15 and router (name:
> r-14-VM, id: 15) are both in MASTER state! If the problem persist, restart
> both of routers.
> No errors in the logfiles, I have tried rebooting the virtual routers.
> Migrating the second virtual router onto the same host will fix the state to
> MASTER and BACKUP, but it's not the point - As the virtual router is supposed
> to run on each host.
> Looking at the console on both virtual routers, you will discover that
> keepalived, conntrackd and haproxy failed to start.
> Trying to ping the virtual routers by their local-link address. from
> management-server, you will discover the following result:
> This is the server running on same host as the instance.
