I tried running qemu-system-x86_64 -help" command manually. But it seems
that it work normally. Here is the output. Kindly guide me.

Are you sure that you called the right program located in
/usr/local/bin?

Do that exactly as libvirt did it:

$ LC_ALL=C PATH=/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/sbin:/sbin:/bin
/usr/local/bin/qemu-system-x86_64 -help
$ echo $?

Does that make a difference?

Which OS are you using? Do you have AppArmor or SELinux enabled?

Another thing you could do is start libvirtd with debug logging
enabled, see
http://libvirt.org/guide/html/Application_Development_Guide-Connections-Debug.html
and post the log.

Claudio

Hi,

Yes, I have called the exact program and the command works smoothly.

I am using Ubuntu12.04.

Currently, I am re-installing everything from the beginning and will let
you know if problem is solved else will look for debug logging of libvirt.

Thanks for reply and help.

Thanks,
Sanket
