House [1] is an earlier try to build an OS with Haskell. Here is a incomplete comparison between House and HaLVM:
- HaLVM is in active development and supports GHC 7.8.3, while House is a little outdated. The Lighthouse project ended in 2010 and was using GHC 6.8.2 version. And you can also get a 2009 version of House which has Gadgets support in GitHub.
- HaLVM is more "lightweight" and more hardware-compatible since it is built on Xen. House is much more heavier with a bunch of C code and bare-metal supporting code.
- HaLVM is an "Unikernel", or "Library OS", while House is more like a traditional OS. For example, House took care of paging (in Haskell!) but HaLVM doesn't have to. And House even has a GUI.
- HaLVM is more for real-purpose usage while House is more academic-oriented. HaLVM doesn't even have a paper for it. (But some academic projects(EsseOS [2], source not available) were built on top of HaLVM)
