I think it's important to see that code to understand the advantages/disadvantages compared to the existing Xen paravirtualization interface. Likewise, any Xen performance data would be useful as there has been some discussion about whether VMI would negatively impact Xen performance[1]. Thanks, Anthony Liguori > Two final notes.
