I need to install Ubuntu Server on RHEL (Red Hat Enterprise Linux) Server 6.5. I went with the KVM route until I realised that Ubuntu isn't listed as a supported "guest" Operating System (https://access.redhat.com/articles/973133).
I'm really stumped as the solution I need to install specifically requires Ubuntu. The RHEL server is already in production and I just want to run the Ubuntu on top of this. What are my options here?
Edit:
I've considered Docker, but requires RHEL 7. VirtualBox isn't recommended for production by this communnity (Is virtualbox good for live server virtualization). Sure there should be a production ready environment for this, isn't there?
