Will post a new version later today. Am testing now with Laszlo's mock up from a previous note. I'm also going to write a qtest test case to try and validate all of this behavior (minus the KVM bits). > I wonder what it would take to work around the KVM bug in qemu though; > can we actually *emulate* 16-bit mode instead of using KVM, on the > kernels where KVM is broken?

I even worked on this way back in the day with Xen. It sucked pretty bad. The challenge in support SMP eventually scared me off of it. http://new-wiki.xen.org/old-wiki/xenwiki/HVM/V2E.html Regards, Anthony Liguori > > -- > dwmw2
