Hi,

The diagnostics I provided shows that it only appears to be listening on
the VIP and not the guest IP..
The DNS does resolve (DNS resolution provided earlier), however I believe
it should resolve to the VIP address as the password server is only
listening on the VIP.

I am using the template 'systemvm-kvm-4.15.1'
The bug you have highlighted is about ubuntu.

This is the password server command line:

python /opt/cloud/bin/passwd_server_ip.py 10.1.1.1,10.1.1.154

And, you can see it only takes the first IP address to listen on:

    if len(sys.argv) > 1:
        addresses = sys.argv[1].split(",")
        if len(addresses) > 0:
            listeningAddress = addresses[0]
            allowAddresses.append(addresses[0])
        if len(addresses) > 1:
            allowAddresses.append(addresses[1])

    server_address = (listeningAddress, 8080)
    passwordServer = ServerClass(server_address, HandlerClass)

I do not think that listening on the VIP is the problem,  I believe
that 'data-server.' should resolve to the VIP address and not the guest IP
address.
