[Qemu-devel] Latest GIT doesn't work with long device names

[Peter Lieven]

Hi,

I just compiled latest git to work on Bug #585113 .

Unfortunately, I can't start the the VMs with the device mappings 
generated by our multipath
setup.

cmdline:
/usr/bin/qemu-kvm-devel  -net none  -drive 
file=/dev/mapper/iqn.2001-05.com.equallogic:0-8a0906-88961b105-19f000e7e7d4beaa-test1,if=scsi,boot=on,cache=none,aio=native  
-drive 
file=/dev/mapper/iqn.2001-05.com.equallogic:0-8a0906-89661b105-458000e7e804beaa-test2,if=scsi,boot=off,cache=none,aio=native  
-drive 
file=/dev/mapper/iqn.2001-05.com.equallogic:0-8a0906-8a361b105-928000e7e834beaa-test3,if=scsi,boot=off,cache=none,aio=native  
-drive 
file=/dev/mapper/iqn.2001-05.com.equallogic:0-8a0906-8af61b105-d10000e7e864beaa-test4,if=scsi,boot=off,cache=none,aio=native  
-m 1024 -cpu qemu64,model_id='Intel(R) Xeon(R) CPU           E5520  @ 
2.27GHz'  -monitor tcp:0:4005,server,nowait -vnc :5 -name 'ide-test'  
-boot order=dc,menu=on  -cdrom 
/home/kvm/cdrom//root/KNOPPIX_V6.2.1CD-2010-01-31-DE.iso -k de  -pidfile 
/var/run/qemu/vm-153.pid  -mem-path /hugepages -mem-prealloc  -rtc 
base=utc,clock=host -usb -usbdevice tablet

error:
qemu: could not open disk image 
/dev/mapper/iqn.2001-05.com.equallogic:0-8a0906-88961b105-19f000e7e7d4beaa-test1: 
Argument list too long

Can somebody help here please. I justed started digging into the code 
and found that filename is a character array of 1024 Byte. So the 
problem must be somewhere
else...

BR,
Peter
