libvirt users - Mar 2014 - 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.

Libvirt only looks into precompiled locations (default to /usr/bin) if
you fail to specify an explicit location; but you can force libvirt to
use your version of qemu by specifying the <emulator> element under
<devices> in your domain XML.

Actually we will search through $PATH for QEMU binaries, so if you
install somewhere unusual, just make sure libvirtd sees an updated
$PATH env variable including the new location.
