Resolution: Not A Problem
> RvR should present virtual IP for name resolution

> Key: CLOUDSTACK-9400
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-9400
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Affects Versions: 4.8.0
> Reporter: dsclose
> Priority: Minor
> Labels: easyfix
>
> Virtual routers are assigned name servers via the kernel arguments. These
> name servers are also presented via DHCP to guest VMs - but the virtual
> router prepends these name servers with it's own guest IP. This allows the
> virtual router to act as a name resolver for guest VMs.
> With redundant virtual routers, the router's guest IP is not the same as the
> virtual gateway IP. This means that after a failover or a network restart,
> guest VMs will not be able to find the name server assigned via DHCP and this
> causes delays whenever name resolution is needed.
> Redundant virtual routers should provide the guest gateway IP to guest VMs
> instead of their own guest IP. This will allow name resolver functionality to
> continue after failover or network restart events.
