-nographic is an alias for "-chardev stdio,signal=off,id=serial0 -serial chardev:serial0 -graphic none". You can't opened it twice, so you don't have to specify again. What you need is: qemu-system-ppc -m 1024 -net nic -net tap,ifname=tap0,script=no,downscript=no ppc.img -cdrom debian-504-powerpc-netinst.iso -boot c -nographic > and chardev does work so long as graphics is enabled (not that I would > figure out that -serial stdio should be replaced with that) > > $ qemu-system-ppc -m 1024 -chardev stdio,signal=off,id=serial0 -serial > chardev:serial0 -net nic -net tap,ifname=tap0,script=no,downscript=no > ppc.img -cdrom debian-504-powerpc-netinst.iso -boot c > > which is sort of annoying but I guess I can redirect graphics to VNC. > VNC is unusable for me due to key repeat issues but that's what the > serial input should work around. > What do you mean by it doesn't work? -serial stdio is equivalent to "-chardev stdio,id=serial0 -serial chardev:serial0", and it redirects the serial port to stdio. The only difference is that your are disabling signaling. -- Aurelien Jarno GPG: 1024D/F1BCDB73 [email protected] http://www.aurel32.net -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
