qemu-i386 on ARM bash: fork: Invalid argument

[moonman]

Good time of day everybody,

I have been trying to make usermode qemu on ARM with plugapps (archlinux) with archlinux i386 chroot to work.

1. I installed arch linux in a virtuabox and created a chroot for it with mkarchroot. Transferred it to my pogo plug into /i386/
2. I comiled qemu-i386 static and put it into /i386/usr/bin/
./configure --static --disable-blobs --disable-system --target-list=i386-linux-user
make

3. I also compiled linux kernel 2.6.38 with CONFIG_BINFMT_MISC=y and installed it.
uname -a
Linux Plugbox 2.6.38 #4 PREEMPT Fri Mar 18 22:19:10 CDT 2011 armv5tel Feroceon 88FR131 rev 1 (v5l) Marvell SheevaPlug Reference Board GNU/Linux

4. Added the following options into /etc/rc.local
/sbin/modprobe binfmt_misc
/bin/mount binfmt_misc -t binfmt_misc /proc/sys/fs/binfmt_misc
echo ':qemu-i386:M::\x7fELF\x01\x01\x01\x00\x00\x00\x00\x00\x00\x00\x00\x00\x02\x00\x03\x00:\xff\xff\xff\xff\xff\xfe\xfe\xff\xff\xff\xff\xff\xff\xff\xff\xff\xfb\xff\xff\xff:/usr/bin/qemu-i386:' >/proc/sys/fs/binfmt_misc/register

5. Also copied ld-linux.so.3 (actually ld-2.13.so because ld-linux.so.3 is a link to that file) from /lib/ to /i386/lib/

6.Now i chroot into /i386 and I get this:
[root@Plugbox i386]# chroot .
[II aI hnve ao n@P /]# pacman -Suy
bash: fork: Invalid argument

7.I also downloaded linux-user-test-0.3 from qemu website and ran the test:
[root@Plugbox linux-user-test-0.3]# make
./qemu-linux-user.sh
[qemu-i386]
../qemu-0.14.0/i386-linux-user/qemu-i386 -L ./gnemul/qemu-i386 i386/ls -l dummyfile

This doesn't look like a qemu-linaro version number -- can you clarify which version of qemu you're using, please?

[moonman (moonman-ca)]

Yes, you are right. I should have reported the bug to general qemu. I compiled it from source.

[Peter Maydell (pmaydell)]

OK, I'm going to close this bug as invalid since you've filed 739785 against qemu, and we'll deal with it there. Thanks.
