Erik Poupaert writes "I've been following VMWare and plex86 (used to be freemware) for a while now, because I think that virtualization may be a solution to quite a number of problems. It basically allows you to run several operating systems concurrently. IBM uses this approach too, to run a large number of Linux instances on their mainframes. While you can leave the task of managing devices and device drivers to the host operating system, guest operating systems can supply you with the ideosyncracies of their particular versions to run the applications that expect them. Since VMWare is not free, as in free speech, I thought that plex86 would become the lead open-source project in the field. Now there seems to be a new player, that I never heard of before, called VOS, who claims the whole field to themselves, and have filed patents to obtain a monopoly on the entire discpline. Have they got any chance in succeeding? Or do you think that the patent office would not grant such patent?"

CentrX writes "I was surprised that no one has contributed a story about FreeMWare since they started. FreeMWare is "an extensible open source PC virtualization software program which will allow PC and workstation users to run multiple operating systems concurently on the same machine." Like VMWare, only free and open-source. They now have a CVS repository and the latest source can be downloaded. I think this project is needed and needs some support from the community. You can also join the mailing list." FreeMWare was mentioned briefly here in April. Looks like it's come a long way since then.
