Even if the virtual machine is not using CPU extensions, running virtualbox hangs the entire system. At a minimum the program should warn the user that kvm is loaded and refuse to start. Even better would be for the cpu extensions option to greyed out and virtualbox play nice with KVM. I hand removed the modules a couple of times, but certain updates put them back in. This is expected behavior as KVM is the default virtualization tool in Hardy." defect closed other VirtualBox 1.6.0 fixed kvm system crash other other
