[libvirt-users] Connecting libvirt to manually compiled QEMU
Hello I have manually compiled a customized qemu (1.4.0) which runs fine on its own (create VM etc) but I want to access this qemu through libvirt (virt-manager, virsh etc). But the libvirt driver only looks into "/usr/bin" for qemu binaries, how can I tell libvirt to connect to my qemu which is placed at "/home/user/qemu" directory. -- Asadullah Hussain
