<div dir="ltr">Hi Nio,<div> </div><div>also, with virtual box 'additions' only add them on a per VM basis. I tried to add it to my boot kernel and completely borked it (needed a full re-install). As this was just "what happened to me" I've not raised a bug for it. Jonathan did the last classroom session on VBox[1], I do have it installed and as you know I will use it when cross checking issues. With the increase use of cloud, kvm is also at the heart of that. Vbox / parrallels etc. are much like chosing which flavour of linux you prefer. I'd always suggest people try the various ones out and decide which is best for them. </div> <div> </div><div>I've never come across a BIOS that disables the hardware virtualisation, but it could happen.

In some ways it is more powerful and flexible than VirtualBox. Thank you very much for the tip :-) Now what did you want to do with the OBI and KVM? Have you got any time for it now? When will you need it? [I'm including the following details hoping they might be useful for several people, who have not yet used KVM] I have installed a virtual machine using KVM, qemu, and virt-manager according to this wiki page <a href="https://help.ubuntu.com/community/KVM/VirtManager" target="_blank">https://help.ubuntu.com/community/KVM/VirtManager</a> It works very well, for example it is easy to use USB pendrives, also to boot from them, and to use image files (dd-cloned images) as virtual disks. Select 'i', the tab with the setup information about the virtual machine. Right-click in the window for specifications and select 'Add Hardware'. Select 'managed or other existing storage', and click the button 'Browse local'. - Select the block device for the USB pendrive, for example /dev/sdb (yes it is that simple), or - Select the file for the dd-cloned image, for example dd_lubuntu-13.04-obi-sept1_4GB.img (This image file contains the One Button Installer with the named tarball.) The host machine must use either Intel VT or AMD-V chipsets that support hardware-assisted virtualization, and it must be activated or possible to activate in the BIOS, otherwise KVM will work but very slowly (qemu software virtualization), and VirtualBox might be be faster.
