Hardy Heron installs KVM by default, crashes VB 1.6 -> fixed in SVN/1.6.2

[WildSubnet]

VB 1.6 causes Hardy Heron to lock up under Hardy Heron because the kvm module is installed by default in this version of Ubuntu. 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.

Already fixed, but it's rather stupid of the Ubuntu folks to enable it by default given that it prevents any other virtualization software from working.

I don't have enough knowledge to say whether it is "stupid" or not, but I am curious as to why KVM causes so much trouble even if the module is not being used.

The problem is that the kernel module "does things" to the system (i.e. plays around with hardware virtualisation settings in the CPU) as soon as it is loaded, even if it is not used.
