    Performance gain or penalty: 32 vs 64-bit guests?!

    englund Novice

      Hello,

       

      has anyone any benchmarks on this? Will the usual performance gain (usually slim) that you get when running on real hardware apply when you go from 32 to 64 bit guests? Or is there some obscure penalty for running 64-bit guest?

       

      And why isn't VMI Paravirtualization supported for 64-bit guest? Is it just that it isn't finished in RC1 or is it not technically possible? How much of a gain does this give in real world scenarios?

       

      Thanks for any input!
