I'm trying to understand if it is possible to have a Type-1 Hypervisor (bare metal, no host OS) with the ability to view the guest(s) operating system(s) on the same machine.
i.e. I have a XenServer which hosts 2 Windows and 1 Ubuntu server. While they are all manageable remotely, they require another machine to access them.
In the event scenario that no other machine is available, I want to be able to visit the physical host, and connect directly to a guest vm.
I'm looking at the options and for my existing XenServer, it seems that I can only gain text based console view for the guest on the physical host.
It looks like KVM is a natural hybrid Type-1 and Type-2 hypervisor, and even so, might be able to save me some CPU cycles if I descend my Ubuntu VM to the host, hosting KVM.
Are there other options? I am imagining a XenServer/ESXi/Hyper-V Server that can ALT-TAB each OS by using some form of X11 + VNC.
