[libvirt-users] How the libvirtd connect to qemud in source codes?

Hi, I meet a question when reading the libvirt source codes. Could you help me? Coz I plan to link libvirt to a Android Emulator based on QEMU, knowing how the libvirtd connect to qemud is important. I trace the code as following: libvirtd.c contains all the initilization of libvirt daemon, then calling function named qemuRegister to qemu_driver.c which contains three methods:int qemuRegister(void) { virRegisterDriver(&qemuDriver); virRegisterStateDriver(&qemuStateDriver); virNWFilterRegisterCallbackDriver(&qemuCallbackDriver); return 0; } In qemuDriver, I find a function --qemudOpen which, I guess, contains the method what I want. But I failed to find right messages. Could you please give me some tips? I guess there has got to contain related interfaces to connect between libvirt and qemu. Thanks a lot!
