##### SUMMARY
Creating more than one public CIDR in the DefaultGuestNetwork fails to
obtain password from cloud-init metadata server.
##### STEPS TO REPRODUCE
<!--
Deploying instances using the original public CDIR work with both SSH key
and Password authentication. We are using the templates from dl.openvm.com
As the new UI does not allow assinging secondary subnets that have been
added to CS we have used the legacy interface. Further, the new UI does not
allow assigning any IP outside of the original subnet that was added when the
GuestNetwork was created. Using the legacy interface we can add a single IP
from the newly added subnet and this get allocated to the instance successfully.
With this, SSH keys get injected but cloud-init cannot get the password from
the VR.

Network setup from the VR. There are 2 IPs. First one from the original
network subnet and the second from the other guest network we added. Both IPs
are using the same shared network.
