Oracle and SUN Yesterday (today if you're in the US), Sun released the latest version of its virtualisation solution, VirtualBox 3.1. Among speed improvements and other smaller features, the biggest news is that Virtualox 3.1 introduces something called teleportation: you can move running VMs between machines - servers or clients, different architectures, different host operating systems, it doesn't matter to VirtualBox. Coincidentally, this reminded me of an idea I once had about moving running applications between machines.

You store the actual VM image on shared storage (NFS, CIFS, iSCSI, etc). It's only the in-use memory that is transported from one host to the other.

And what if I need to change/migrate the area in that such VM image is stored ? Is there a way to move it having the VM running ? - this is my understanding of "VM transportation", not only the instance, but the image too.

Remote X11, rdesktop, VNC, and NX allow you to do this already, although not as seamlessly as some would like.

Well, I was thinking in something that changes the presentation itself - like when a web page knows if you are using a browser in a desktop or in a mobile device. Doing a VNC/RDesktop of a desktop sized screen in the mobile device will be a scrolling challenge.
