Antoine, Works for me with master branch. Its likely this commit fixed it: commit 76d4622776d007de3f90f311591babc5f6ba6f39 Author: Avi Kivity <avi@xxxxxxxxxx> Date: Tue Sep 1 12:03:25 2009 +0300 KVM: VMX: Check cpl before emulating debug register access Debug registers may only be accessed from cpl 0. Unfortunately, vmx will code to emulate the instruction even though it was issued from guest userspace, possibly leading to an unexpected trap later. It will be included in 2.6.30 / 2.6.27 stable (.29 is not maintained anymore). -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
