error: internal error process exited while connecting to monitor

出现以上报错解决方法：

# virsh start vmhost1  

error: Failed to start domain vmhost1error: internal error process exited while connecting to monitor: kvm: -drive file=/dev/sp1368155439693/v1368544020461,if=none,id=drive-virtio-disk0,format=qcow2: could not open disk image /dev/sp1368155439693/v1368544020461: Invalid argument

因镜像格式错误，可以用qemu-img info 检查镜像和xml配置文件中指定的type是否一致！
