I am also interested in looking at high-reliability servers for running network services, and in rollback technology for linux. Fast UML transition from "not running" to "ready for work" would be good for some tasks too. Checkpointing and migration of UML instances are of particular interest to me here. I also run linuxzoo.net, where student get their own UML image to play with. Rather than shutting down and booting up their individual machines, I could simply= =20 suspend them for reload later. But there are many uses for hybernation mechanisms. Have a look at the presentation that the sbuml author produced to get a few= more applications of this technology. |
