Now, admittedly, a) I really haven't been following this thread, and b)
haven't worked a lot with VMs, and not with KVM, but could you clarify
something for me? Are you trying to make the virtual root disk larger, or
are you creating a new one, and just adding it the the VM, like mounting
another drive on an existing system? If the latter, can't you mount it?

Oh, and is the new virtual drive formatted?
