[SystemSafety] Using a virtual machine to develop safe code / logic

[Daniel Grivicic]

Hello List members,

Is there any information or evidence supporting the statement that "safety
related logic shall not be developed using a virtualised environment".

My specific problem is that I have an older process safety control system
that is not supported on a recent operating system. Specifically the
programming and monitoring program (for the control system) will only
install on Windows 2000. Windows 2000 will not install on a new computer
(driver problems) so a solution is to use a virtual machine.

The company that supplies the programming software does not support the
installation or use on a virtual machine. The solution being a processor
and operating environment upgrade.

Is there a difference between using a physical computer compared to using a
virtual / software based one?

Your input into this is appreciated.

Thank you.

Daniel Grivicic.
