Welcome to the Community,
the ESXi hypervisor is a purpose built OS, and doesn't provide a grahical console for the VM's running on it. If you want/need to access a VM's console, you'll have to access the host using the vSphere Client, or - with the latest releases - throough the built in HTML5 web UI.
Hi and welcome to the forums,
Can you give a little bit more information on how you are running VM's which VMware product are you trialling on your Linux pizza box?
As the previous reply has said VMware's hypervisor ESXi is a full blown bare metal OS so we need to know what product you have installed on your Linux pizza box.
So as soon as you can give us some more details we can give some advice.
