Talk:Emulating the XO/Quick Start

Qemu: You do not have enough space in '/dev/shm'

When I run:

$ qemu -m 256 -kernel-kqemu -soundhw es1370 -net user -net nic,model=rtl8139 \
       -hda olpc-redhat-stream-ship.2-devel_ext3.img
Could not configure '/dev/rtc' to have a 1024 Hz timer. This is not a fatal
error, but for better emulation accuracy either use a 2.6 host Linux kernel or
type 'echo 1024 > /proc/sys/dev/rtc/max-user-freq' as root.
You do not have enough space in '/dev/shm' for the 256 MB of QEMU virtual RAM.
To have more space available provided you have enough RAM and swap, do as root:
umount /dev/shm
mount -t tmpfs -o size=272m none /dev/shm

I did what qemu suggests about /dev/shm and it worked. Awesome! --Ashawley 16:00, 27 December 2007 (EST)

Net and Sound on Windows XP

I've got the emulator working with the 657 dev build, but the "-net user -net nic,model=rt18139" parameters won't work, nor does "-soundhw es1370" or "-soundhw all".

I'm running a Dell Inspiron 1520 laptop with WinXP, and the sound hardware is a SigmaTel HiDef audio device, but I can't figure out what to feed the -soundhw argument to let it use this device.

For Networking I'm using an ASIX AX88772 USB 2.0 to Fast Ethernet converter, though I could go to the Broadcom 440x 10/100 Integrated controller. For wireless I'm using the Dell Wireless 1390 WLAN mini-card.

Are there known parameters (args) I can feed the two options, or am I stuck without sound and networking until my G1G1 arrives?

Just to clarify, the emulator and OLPC (Sugar, etc.) boot and run OK, it's just that I'm without sound and networking.
