Nested-svm is in better shape) I tested the following scenarios: - Linux on Xen on Xen - NetBSD on Xen on Xen - KVM (+ KVM-guest) on Xen - KVM (+ KVM-guest) on Xen on Xen (yeah, l3 guest works!) - Windows 7 (both 32bit and 64bit) on Xen on Xen - Win7 XP mode on Windows 7 (both 32bit and 64bit) on Xen - Hyper-V (64bit) on Xen - VMware ESX (64bit) on Xen Issues: - Hyper-V SMP not tested, only UP - Win7 XP mode often quits with BSOD, but when it boots playing Solitair makes fun :-) - L2 guest screen doesn't refresh in graphical mode (VGA text mode works), workaround: dis- and re-establish the VNC connection, between two VNC reconnects you can work like with your monitor powered off Christoph -- ---to satisfy European Law for business letters: Advanced Micro Devices GmbH Einsteinring 24, 85689 Dornach b.
