> Earlier we used to use the eth0 ip of the router to get the public key and
> user-data. now with the multiple subnets the user data needs to be accessed
> by the name data-server instead of the eth0 ip.
> We used to fetch the eth0 ip of the router from the dhcp files in the VM. For
> VMs in new subnet this will be one of the ipalises on the router eth0
> interface. using this ip to access user-data will not work for new subnets as
> the service is not running on the alias ips. so we now use a name data-server
> to access the user-data and public key . The name gets resolved by the
> dnsmasq to the primary ip of the eth0 interface .
> In case of ssh-key reset we have modified the script to fetch the public key
> using the name data-server instead of the eth0Ip of the router. So if some
> one wants to use this multiple ip ranges feature they will need to update the
> uservm templates with this modified ssh-key rest script. All VMs deployed
> prior to using this feature will be able to use the ssh-key reset with the
> old script. The updating of the templates is required for the VMs which will
> be deployed in the new subnet.
