We might back-port the vm86 and full /dev/mem support to 2.4, but its not high on the todo list. Perhaps a volunteer from the audience will step up at this point ? :-) > reaction times on my system are anything but good (what > performace loss should i expect if i use a file-backed vbd (and what > fs is the most for those). also network seems pretty slow. The performance loss using file-backed vbd's is typically pretty small, but I do generally use LVM volumes. Our systems manage to saturate gigabit Ethernet links no problem, so I'm surprised you're seeing network slow downs. There have been reports about IRQ problems causing slow downs on some systems, and we're investigating.
