Running RTOS on a Virtual Machine?

Unfortunately INtime for Windows does not support being installed alongside or within a virtual machine. It requires some minimum amount of virtualization capabilities which are not available when either a virtual machine is installed (or running. I tried this a while ago), or when installed within a virtual machine.

However, INtime does have a hypervisor product. Though we have decided not to pursue it for the current releases of INtime, we may look more into it in future versions.

That said if you are just looking to do software testing, have you looked into mocking frameworks? If you simply need to “start” the network, or respond to simple state changes that may be sufficient.
If what you’re trying to do is more complex then I think using the whole motion controller is probably the way to go (this is how we do our testing at RSI, though we split up our tests between those that requires hardware and those that don’t)
