If it doesn't boot, there are always screen shots or netconsole if you're serial port challenged. KVM is a hypervisor, it has nothing to do with your system not booting. More likely it's something with the IOMMU. Does disabling VT-d help? What about booting with iommu=pt? BTW, reproducing on another W520 doesn't mean the hardware isn't broken, it just means this isn't a point defect. Hardware is broken a disturbing amount of the time. -- You are receiving this mail because: You are watching the assignee of the bug.
