vBlades: optimized paravirtualization for the Itanium processor family

Daniel J. Magenheimer, Thomas W. Christian · 2004

Virtualization of an uncooperative architecture often has severe performance consequences. Paravirtualization has recently been suggested as a solution to performance issues, but it introduces unacceptable supportability problems. The HP Labs vBlades project has identified a novel hybrid approach - which we call optimized paravirtualization. We examine methods for both virtualizing and paravirtualizing the Itanium processor, and then demonstrate optimized paravirtualization to maximize performance while simultaneously minimizing supportability concerns.
