Howto set up Virtual Box in Ubuntu
(including Karmic Koala -- 9.10)
This howto is for all newbies that will need virtual
box in Ubuntu ( especially the new 9.10 Karmic Koala ). We were amazed
when we saw that Virtual Box is not working "Out of the Box". Thats ok!
We were able to fix this in a couple easy and simple steps:
NOTE: This howto
applies only for Ubuntu
1. Installation
~ $ sudo apt-get install
virtualbox-ose
This should pull out the required dependencies, but if not these are
all the needed packages:
virtualbox-guest-additions
virtualbox-ose-dbg
virtualbox-ose-guest-source
virtualbox-ose-guest-utils
virtualbox-ose-guest-x11
virtualbox-ose-qt
virtualbox-ose-source
After installation is complete you can start it up, but most likely to
end up with error like:
VirtualBox
can't operate in VMX root mode. Please disable the KVM kernel
extension, recompile your kernel and reboot
(VERR_VMX_IN_VMX_ROOT_MODE).
To fix this, there is no need of recompiling the kernel. All you have
to do is to unload module "kvm_intel" and
backlist it as well! or simply remove the package qemu-kvm (For unknown reasons with installing Virtual Box Ose the compiler automaticly
installs this package, which cause the loading of that module, so if you don't need it just remove it!)
To remove qemu-kvm simply execute this command:
~ $ sudo apt-get remove qemu-kvm
Removing this package will fix the issue, but if you need it just simply follow this two easy steps:
To unload the module execute the command:
~ $ sudo modprobe -r
kvm_intel
And if you try to start Virtual Box you will succeed
To automate this proccess and avoid manually unloading the module you
can add it to "/etc/modprobe.d/blacklist.conf"
~ $ sudo nano
/etc/modprobe.d/blacklist.conf
and add the following line at the end of the file :
blacklist kvm_intel
That's all folks, so easy no need to recompile kernel! Now on the next
boot this module will not be loaded!
