Hi Paul.

(not specifically the entire host operating system, just the kernel). KVM will need to be explained by someone else, the only understanding I have with this is it relies on virtualisation in the processor to switch between os's. With the benifit being you can run M$Windows if you want to. There is no way to run windows with LXC. Can one run inside a LXC container a KVM ? > If the guest container have the correct privileges, then I would assume so. But I would suggest this would be a messy way to do things, and breaks the whole container concept. The processes in the container are ment to be 'contained' yet to get the correct kernel priveleges to do complete KVM switching would be to open up the entire container to the rest of the system (if thats even at all possible, it may not be! The kernel may not provide the correct privileges to do KVM virtualisation within a LXC guest) Can one run inside a KVM some LXC containers ? > > This one I would say definitely. Since you are running a completely new kernel, I cant see a reason why you couldn't provide an LXC kernel to run within a KVM guest.
