Mapping KVM guest VMs to subdomains

Question

I've just installed KVM on a Ubuntu host system and intend to install two guest VMs on it. I have a domain, e.g. example.com. How can I configure my system so that VM(a) is accessible by example.com and VM(b) is accessible by internal.example.com?

Answer 1

Assuming the VM's have publically accessible ip addresses (that's a different question) you will want to contact whoever manages the example.com dns server and provide those ip addresses so that they can add these two systems to it.
