[libvirt-users] qemu driver boot up

Hi,   Looking to libvirt source code questions:   a) I see virt-mgr or such client invokes libvirt API which inturn connects to libvirtd on host. Is this right ?  Further libvirtd invokes qemu driver callbacks which were registered when it comes up using: qemuRegister() API. Is this right ?   b) If (a) is true then does is mandate that (i) libvirtd daemon need to be running on host only ?  (ii) also libvirtd daemon need to be running before qemu (to register) ?    c) what is the call sequence and boot up flow between libvirtd daemon and qemu ?   d) can libvirtd process run in a guest ?   Thanks !   CM.
