This is misleading. VMWare does not emulate the processor, but it does do dynamic rewriting of the executing code to make it run in ring 3. You're running native code, but parts of it are first rewritten on the fly. That's a large part of the reason why Xen's performance is much better. BTW, there's another approach from the L4 guys, known as "afterburner", which is to modify the tool-chain to paravirtualize the OS while compiling it. The consensus so far is that almost everyone would rather hack their kernel than their toolchain ;-) Cheers, Muli -- Muli Ben-Yehuda http://www.mulix.org | http://mulix.livejournal.com/ ================================================================= To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
