Try to run another SDL application like Frozen Bubble (game). If it works, then qemu may be trying to use shared memory on the X Server, also known as SHM, MIT-SHM, etc. When the application and the X server are on the same machine, the application can directly pass data to the X server using shared memory for speed. This obviously doesn't work when the two are separated by a network. I don't recall if I had this issue when I built qemu, but I have run across this with some applications. Generally there is a --disable-shared-mem or --disable-shm option, or (even better) a run-time option.
In a related note, since this app uses SDL, which tends to blast rectangles of pixels at a time, qemu can really use up some bandwidth if a lot of screen updates occur in the hosted OS. In those cases you may want Gigabit on the terminal to avoid sluggish updates. I've seen network usage get up to 10-12MB/s, which exceeds the 7-8MB/s that you'll get with a 100Mb NIC. -Todd ------------------------------------------------------------------------- Take Surveys.
