This appears to be an interesting way of solving an HA problem:
http://nss.cs.ubc.ca/remus/papers/remus-nsdi08.pdfIt is also different from a typical approach of checkpointing in HPC. One thing that I'm wondering about though is whether Plan9 architecture of things like /net and /dev/sd would actually allow it to be HAed in that fashion *without* a help of the hypervisor. Does it make sense or am I totally off base here? Thanks, Roman.
