I'd like to see some indication though other than "seems reasonable" as to what the value should be. For instance, if a Fedora 12 install doesn't work without 256M, that's a solid argument to bump the allocation. Short term, I'd like to see this globally configurable. > * virtio is used for disk and network for nice performance gains > The problem with virtio is that very few OSes have the drivers right now. For networking, we can do better, and I've just written a spec for a new feature to attempt to address this[1].
