That's impossible, because libvirt owns the QMP monitor and cannot delegate use to another process. A core part of the VM startup process requires that libvirt talk to the QMP monitor to accomplish work, as well as to receive ongoing notifications of changes in state. What is the debugger program you are using ? It really needs to be updated to use the libvirt APIs instead of QEMU monitor directly. Libvirt provides an API for issuing monitor commands which it should be able to use. It is just a question of re-writing the debugger to know about this.
