Ok, it seemed as though "ls" worked from "strace -ff -o ls-strace-
alignment-2.log chroot /i386 /usr/bin/qemu-i386 /bin/ls"
so I tried to execute the package manager:
address@hidden ~]# chroot /i386 /usr/bin/qemu-i386 /usr/bin/pacman -Suy

Title:
qemu-i386 user mode on ARMv5 host fails (bash: fork: Invalid argument)
Status in QEMU:
New
Bug description:
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:
address@hidden i386]# chroot .
[II aI hnve ao address@hidden /]# pacman -Suy
bash: fork: Invalid argument
7.I also downloaded linux-user-test-0.3 from qemu website and ran the test:
address@hidden 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
