One simply needs the plausible claim that digital processes on a computer are real, and that virtual reality consists in digitasl processes on a computer. These claims can be accepted by people with all sorts of metaphysical commitments (pg. 34).
Conclusion: Virtual Reality is not a second-class reality.
