Looks like qemu is hung and is not responding to commands libvirt sends to the QEMU's monitor socket. And since this happens while libvirt is in the process of starting up the domain (it sends several commands to QEMU before it starts the virtual CPU and considers the domain running), you see a hanging virDomainCreateWithFlags API.
