Subject [jira] [Created] (CLOUDSTACK-9400) RvR should present virtual IP for name resolution
Date Wed, 01 Jun 2016 14:37:59 GMT
dsclose created CLOUDSTACK-9400:

             Summary: RvR should present virtual IP for name resolution
                 Key: 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

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

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.
