Bug Description

Binary package hint: qemu

I'm on Ubuntu 8.04.1,

the affected package is qemu 0.9.1-1ubuntu1

This is my command line:

qemu -M pc -hda /home/catonano/Scrivania/openwrt-x86-jffs2-128k.image -m 64, -net nic,vlan=0 -net user,vlan=0,hostname=emu -boot c

With this, the keyboard layout is wrong, so I can't type the colon, the slash, the question mark.

I tried adding the "-k it" switch, like this

qemu -M pc -hda /home/catonano/Scrivania/openwrt-x86-jffs2-128k.image -m 64, -k it, -net nic,vlan=0 -net user,vlan=0,hostname=emu -boot c

the result is:

Could not read keymap file: '/usr/share/qemu/keymaps/it,'

The same thing happens with the "-k fi" switch, I just tried a different layout file.

Now, look:

ls -l /usr/share/qemu/keymaps/it
-rw-r--r-- 1 root root 2462 2008-02-13 04:18 /usr/share/qemu/keymaps/it

The file is readable by anyone.

So why can't it read it ?

I tried to trace the call with strace but frankly I can't understand the output. There's an interesting line, though:

_llseek(3, 0, 0xbfda8758, SEEK_CUR) = -1 ESPIPE (Illegal seek)

This is the complete output:

sudo strace ./qemu.sh
execve("./qemu.sh", ["./qemu.sh"], [/* 16 vars */]) = -1 ENOEXEC (Exec format error)
dup(2) = 3
fcntl64(3, F_GETFL) = 0x2 (flags O_RDWR)
fstat64(3, {st_mode=S_IFCHR|0620, st_rdev=makedev(136, 0), ...}) = 0
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xb7f88000
_llseek(3, 0, 0xbfda8758, SEEK_CUR) = -1 ESPIPE (Illegal seek)
write(3, "strace: exec: Exec format error\n", 32strace: exec: Exec format error
) = 32
close(3) = 0
munmap(0xb7f88000, 4096) = 0
exit_group(1) = ?
Process 13858 detached

To reproduce this , just install qemu and run it with any image AND a "-k it" OR "-k fi" switch.

Thanks

Sorry I tried a more readable command line and got a more readable output too ;-)

adriano@adriano-laptop:~$ strace qemu -M pc -hda /home/adriano/Scrivania/openwrt-x86-jffs2-128k.image -m 64, -k it, -net nic,vlan=0 -net user,vlan=0,hostname=emu -boot c

execve("/usr/bin/qemu", ["qemu", "-M", "pc", "-hda", "/home/adriano/Scrivania/openwrt-"..., "-m", "64,", "-k", "it,", "-net", "nic,vlan=0", "-net", "user,vlan=0,hostname=emu", "-boot", "c"], [/* 35 vars */]) = 0

_llseek(4, 0, [0], SEEK_SET) = 0

open("/usr/share/qemu/keymaps/it,", O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or directory)
write(2, "Could not read keymap file: \'/us"..., 58Could not read keymap file: '/usr/share/qemu/keymaps/it,'
) = 58
exit_group(1) = ?
Process 23907 detached

Where the interesting line is:
open("/usr/share/qemu/keymaps/it,", O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or directory)

And:

adriano@adriano-laptop:~$ ls -l /usr/share/qemu/keymaps/it
-rw-r--r-- 1 root root 2462 2008-02-13 04:18 /usr/share/qemu/keymaps/it
adriano@adriano-laptop:~$

So ls CAN access the file, qemu can NOT.

I really wonder why !

I discovered this with qemu, but now I disinstalled qemu and using kvm and if you substitute "qemu" with "kvm" in my commandlines, the simptom is EXACTLY equal. It's there

I just didn't spell correctly the command
