With plex86, the goal is to run the stock x86 port. Plex86 is also x86-specific. > Do you think you can make it faster? To get any level of security with UML, you need to use "jailed mode" in which performance takes a big beating. To fix this, you need patches to Linux as a host, to make it offer a better environment for running UML guests. From a commercial perspective, then you have a patched Linux host + totally different port of a Linux guest. >From a fun perspective, I think UML is fantastic achievement. What I'm aiming for is a stock Linux host and a stock Linux guest, the small mods to macroize PUSHF/POPF being a minor concession to accomodate a broken PVI support in x86. -Kevin __________________________________________________ Do you Yahoo!?
