I have attempted to run CI against this one 3 times in a row on different
CI environments. Every time it is failing with the following:
```

> Minimise VR downtime during network update

> Key: CLOUDSTACK-8751

> Project: CloudStack
> Issue Type: Improvement
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Reporter: Bharat Kumar
> Assignee: Bharat Kumar
>
> Currently we use redundant virtual router enabled networks to prevent network
> outage even if one of the virtual router fails. This is achieved by using
> redundant virtual routers along with VRRP protocol. This has increased the
> network robustness. However updating a network with new network offering
> involves some downtime due to Vr restarts. In case of redundant VR based
> networks we can sequence the network update operations to update the backup
> first and then update the master while master's operations are being handled
> by backup, this way i think we can minimise the downtime.
