漫长的等待过程……
安装Windows需要重启好多次，安装好Windows后用VNC连接客户端
判断依据就是等命令自动结束
# virsh list --all
# virsh edit Cloud_win7_64bit
然后关机，再开机
# virsh list --all
开启虚拟机
# virsh start Cloud_win7_64bit
# virsh list --all
报错，问题已解决
[root@localhost tmp]# qemu-img convert -f raw -o qcow2 Cloud_win7_64bit.img Cloud_win7_64bit.qcow2 Unknown option 'qcow2' Invalid options for file format 'raw'.
