VMWare will run on an openMosix node, but instances cannot be migrated across nodes, nor will VMWare be aware of the other nodes. I mention this so that you do not waste your time, as I have, based on information in the openMosix wiki which states the exact opposite:

If you intend to run VMWare under openMosix so that openMosix would load-balance several instances of that (yes, that works).

Just to be clear, the above is untrue, as confirmed both by my testing and Moshe Bar's comments. Moshe being the founder of openMosix:

I would think it's next to impossible to migrate vmware instances simply because of Vmware's architecture. Vmware scans the exucutable [sic] VM pages of the virtual machine ahead of execution and replaces call to ring 0 of the CPU with system calls and pointers to it's own software. I doubt if a Vmware machine would be able to run on the remote node after migration.

I updated the FAQ in the Wiki. The FAQ indeed was wrong , however as we migrated from an older wiki I have no idea who made those claims.

Thanks. I wasn't sure the wiki was being maintained and so didn't make the change myself.
