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.

About Thom's idea, it is better to be possible do the transportation of the data only, not the whole OS or the application itself. This may sign that you will need same apps in both lands, but it will be faster to migrate than whole OS/App/Data. Otherwise, using a remote session or putting the data in a server is better.
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.
That said, what I really would love is something based in an environment like the Chrome proposal. I'm working in a document in the phone/handheld and when arriving home, I only put it in the cradle and the content is switched to be showed in a better screen, and I can continue to work with other input devices. If I loss the device the content is preserved because it is stored in the server.
Remote X11, rdesktop, VNC, and NX allow you to do this already, although not as seamlessly as some would like.

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.

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.

Regarding the news, it's good if it's for free. VMWare tools are offered only in the paid product.

The transportation is helpful in a scenario in that you can not stop processes in order to do Hardware maintenance/upgrades. And the sync process may take a lot of time if these servers are doing massive data changes.
