UML is a nice thingy because it is Linux ported to itself, but it has limitations. Mostly it's speed (pagefaults and system calls are really slow) and it supports only x86/x86_64. I use UML on systems where KVM is not available. -- Thanks, //richard -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
