Is there any way to get virsh / libvirt to create a domain such that I can later connect to it via QMP (without hacking the code)? The command line that libvirt creates for my current setup looks like this: /usr/local/bin/qemu-system-x86_64 -S -M pc-0.12 -enable-kvm -m 512 -smp 1,sockets=1,cores=1,threads=1 -name winxpsp2 -uuid ab244939-c804-1aff-68b6-9324f174c3c8 -nodefconfig -nodefaults -chardev socket,id=monitor,path=/usr/local/var/lib/libvirt/qemu/winxpsp2.monitor,server,nowait -mon chardev=monitor,mode=control -rtc base=localtime -boot c -drive file=/var/lib/libvirt/images/winxpsp2.img,if=none,id=drive-ide0-0-0,format=raw -device ide-drive,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0 -drive file=/home/username/iso/en_winxp_pro_with_sp2.iso,if=none,media=cdrom,id=drive-ide0-1-0,readonly=on,format=raw -device ide-drive,bus=ide.1,unit=0,drive=drive-ide0-1-0,id=ide0-1-0 -netdev tap,fd=16,id=hostnet0 -device rtl8139,netdev=hostnet0,id=net0,mac=52:54:00:4d:1d:1b,bus=pci.0,addr=0x3 -chardev pty,id=serial0 -device isa-serial,chardev=serial0 -usb -device usb-tablet,id=input0 -vnc 127.0.0.1:0 -k en-us -vga std -device ES1370,id=sound0,bus=pci.0,addr=0x4 -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x5 The important pieces of this command line (I believe) are: -chardev socket,id=monitor,path=/usr/local/var/lib/libvirt/qemu/winxpsp2.monitor,server,nowait -mon chardev=monitor,mode=control However, I'm unable to connect using this path because -- I'm guessing -- libvirt has already connected.
