Hi,    Here is my situation, I install libvirt in a non-default directory and start libvird with sudo. While I can connect virsh to libvirtd using "virsh --connect qemu:///system", I fail to connect my app using "virConnectOpen("qemu:///system")", which complains "unable to locate libvirtd daemon in $PATH".  Then, I take another try and add the path of libvirtd in env variable PATH. Unfortunately, it doesn't work.    I read through the api reference and find no place to specify this path explicitly.

Thanks for any tip. Harvey

I guess I resolve this problem. I test my app with another libvirt.so which is compiled with option "--with-yajl", and my app can connect to libvirtd. The previous libvirt.so was compiled with no "--with-yajl" I don't why this yajl can cause the problem.
