VirtualBox - AMD-V and KVM

I usually use the KVM on my linux host for Virtualisation. It's default with Fedora and I know it. Usually ...

Today I thought I would try the Ubuntu 10.4 Beta 1 on VirtualBox. I installed the latest VirtualBox ( version 3.1.6 ) and then had a crack at installing the Ubuntu 10.4 64bit. Of course an error came up saying that while AMD-v was enabled, it was not operational. After much googleling about, I found that the KVM modules were causing VirtualBox issues with access.

So a quick "rmmod kvm_amd" and "rmmod kvm" fixed it.

Next time I want to use KVM, I will need to re-enable these with, I suppose, a quick, "insmod kvm_amd" and "insmod kvm"
