Failing install with kvm, need to jump to annother virtual console?

When installing under KVM it is sometimes useful to switch to another virtual console to trouble shoot. The problem is it is not obvious how to do this when using JollysFastVNC on a mac. The trick is to disconnect and adjust the "Keyboard Input" under the connection settings to "Immersive", this will make the function keys work as they would if you had a real console. You do not need to use the "fn" key as you would normally do in osx. Once this change is made and you have reconnected switching the virtual console is just a alt-fn key.
