AFAICS the only unsurmountable problems you might encounter is timing
and performance. You can't predict how real hardware will work when it
comes to CPU and memory caches, system buses, hardware interrupts, large
CPU counts, NUMA factors, etc. But if any of those were of any concern
to you, you wouldn't have asked, I guess. ;-)

So, no, I don't think there are any important disadvantages when using
virtualized environment.
