HI Rusty, I wanted to play with lguest. As it was recently merge upstream by Linus, i took a look and the location looks like driver/lguest*. Unfortunately my local git repo cannot get the 2.6.23-rc2 changes from upstream somehow :-/.[duh... says "Cannot get the repository state from http://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git"]. i do not know what i am doing

..., because: 1. VIRTIO_PCI selects VIRTIO and sets it to M 2. VIRTIO_CONSOLE gets forced to M because one of its dependencies is M So either VIRTIO (and VIRTIO_RING) need to be user-selectable, or all of the options that depend on VIRTIO need to be changed to select it instead. (For even more fun, LGUEST_GUEST on i386 forces VIRTIO, VIRTIO_RING and VIRTIO_CONSOLE all to Y.)
