I don't think a realtime OS will work in a virtual machine. I have the same problem with EMC2 in parallels on the mac. The sim machines do work though. You don't consider real machining this way, do you? Dirk By the way I prepare EMC2 for small computer (No cooler, no HDD, small size). I try to make distrib on VMWare, before installing on real computer. Евгений Александрович wrote: I do not think then VMWare is a problem. Linux does not know than VMWare is not real machine. May be only unstable CPU resource ... I think Dirk has it correct. Even if it would work - VM will be pulling interrupts in background and the whole reason of using a realtime kernel is to prevent interrupts. If the machine was fast enough and the demand was low enough, it is possible you could get away with it, but for safety and sanity it pays to keep the computer controlling movements as simple and unencumbered as possible.
