The general idea of this patch is sound, but the implementation is just too ugly. -----snip--- So this should be fixed with the next update. (Tho that may still take a bit since I'm still waiting for resolution on another bug, slirp `sometimes' not working right anymore, see other post.) Actually... If this takes longer than expected I'm thinking of adding back qemu 0.8.2 as a qemu-stable port, do people want that? Two bugs in such a short time is a bit much I'd say... :/ Juergen
