Hypervisors Can Defeat GPLv3's Anti-Tivoization

DeviceGuru writes "A hypervisor can be used to isolate from each other software works released under incompatible licenses, while allowing them to run simultaneously on the same hardware. For example, Linux and Windows CE can run on separate virtual machines on one device, without violating either OS's license. Due to the isolation between multiple VMs running atop a hypervisor, it seems like this architecture could allow companies to build Linux-based devices, such as mobile phones or set-top boxes (think TiVo), that can't be upgraded by their users without authorization, thereby circumventing the GPLv3's 'anti-tivoization' clauses." Here's a white paper with more details from a commercial hypervisor company.

Frankly, I'm not sure what the article is trying to state.

If the code is released under GPLv3, then modifications of the code must be able to run on the same hardware. It doesn't matter if the key to run the code is a checksum or a password to give the hypervisor. Either way, if modification of the client cannot be dropped into the place of the original client (either to run on the same hardware or the same hypervisor), it's in abuse of the GPLv3.

Check and mate, RMS!

You must have a huge stake in proprietary software to cheer about this. Note that if this is the way of the future, it's not only "Check and mate, RMS!", but also "Check and mate, general-purpose personal computer!". Well, I guess you will still be able to import one from China, provided you won't get caught. Hurray indeed.
