Hi Nio,

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.

I've never come across a BIOS that disables the hardware virtualisation,
but it could happen. As lubuntu also has a duty to look after older
chipsets, being aware of what kvm needs is a requirement.

For OBI and KVM, once we get final beta out of the way and make some
progress on the zram bug, I do promise to spend some time checking and
asking questions :)

Regards,

Phill.
