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-D...
and post the log.
