I have got a new server which has Cloudmin installed. It's working well and I can create and manage VM's as expected. The server came with a /29 subnet and I requested an additional /29 subnet to allow for more virtual machines. I didn't want to replace the existing /29 subnet with a /28 because that would have caused disruption with my existing VM's.

To make life easier I decided to configure a domain name for the Cloudmin host server to allow for automatic hostname setup whenever I create a new virtual machine.

I have a domain name (example.com) and I have created an NS record as follows:

NS kvm.example.com  123.123.123.123
A  kvm.example.com  123.123.123.123

In the above example the IP address is that of the host server, I also have two /29 subnets routed to the server.

Now, I've added the two subnets to the Cloudmin administration panel as follows:

I've tried to hide as little information as possible without giving all of the server details away!

If I ping kvm.example.com I get a response from 123.123.123.123, if I ping the newly created virtual machine (example.kvm.example.com) it fails, and if I ping the IP address that's been assigned to the new virtual machine (from the second subnet) it fails.

Am I missing anything vital? Does this look (from what little information I can show) like it's setup correctly?

Any help/pointers would be appreciated.
