VirtualBox OSE

[StrangeFreedom]

I installed VirtualBox OSE and this is the error I get:

VirtualBox can't operate in VMX root mode. Please disable the KVM kernel extension, recompile your kernel and reboot.
VBox status code: -4011 (VERR_VMX_IN_VMX_ROOT_MODE).


Result Code:
0x80004005
Component:
Console
Interface:
IConsole {1dea5c4b-0753-4193-b909-22330f64ec45}

I have had KVM installed, so that might be the cause of the problems.
How do I solve this?

[StrangeFreedom]

Solved by installing bum.
Then disabling kvm service in there.

How should I do it without bum?

sudo /etc/init.d/kvm stop

sudo /etc/init.d/kvm stop

how to make this permanent so it does not restart after reboot? or it is not safe to do that?

[zmunson]

Yes, I too would like to know how to tweak my system so I don't have to drop into a command line and issue this command before running VirtualBox. VirtualBox gives me this error message *some* times that I load it, but not *every* time, and I haven't figured out what the trigger/cause is.

Ideas for a relative ubuntu newbie, anyone?

Thanks!

Well, one can always make a shell script with sequential command to launch, but I know that there is a way to directly disable this module. Just don't know how. It seems that we'd have to wait for the "mercy of the gurus" :)

kvm is another virtualization package which interferes with VirtualBox. You could uninstall kvm.

kvm isn't installed by default on Ubuntu as far as I know, so you must have done something in the past that installed kvm.

how to uninstall it? aptitude doesn't recognize it.
I think it's connected with Intel-based machine as Ubuntu install it by default on all intel machines.

Hmmmm, a very funny thing. Kvm IS NOT installed on my machine (checked via apt-get), but it DOES EXIST in /etc/init.d/kvm. Can I just delete this file so it will not be restarted after reboot??? :confused:
