   > I still have the same issue, even in 4.15.2, it will not work with basic network ( or advanced with guest ) with multiple subnets.
   > 
   > This issue is persistent to the VMs with cloud-init:
   > 
   > Ubuntu 16 - OK
   > Ubuntu 18 - OK
   > Ubuntu 20 - OK
   > CentOS7 - Not working
   > CentOS8 - Not working
   > Debian8 - Not working
   > Debian9 - OK
   > Debian10 - OK
   > 
   > It is simple to reproduce, add multiple CIDR to the same guest router, deploy multiple instances, when a new VM is going to be deployed under different subnet, for some reasons the returned data-server IP is not from VM subnet, it is the IP which is defined in /etc/hosts into the router, example;
   > 149.xx.xx.99 r-xxx-VM data-server
   > 
   > And because it is from different subnet, there is no password saved in the file for different subnet (in router ). in this case, no password is going to be set for this VM.
   > 
   > If I execute this: "cat /var/lib/dhclient/dhclient--eth0.lease | grep dhcp-server-identifier" into the VM the returned IP is the right one. Even if I try to add this to VM host file( IP data-server) ,it is not working, the cloud-init it is using the IP for metadata, and not the host "http://data-server".

   > 4.15.0 + VMware
   > 4.15.1 + VMware
   > 4.15.2 + VMware
