Question

好的我有2台KVM服务器：server_1和server_2。 server_1正在生产中，无法与server_2通信，server_2正在我的测试环境中为生产做好准备。

从server_1我有2个克隆的VM副本（我现在无法关闭正在运行的VM）并将它们移动到server_2。

在使用gui界面的server_2上，我选择Import existing disk image＆gt;存储路径：/home/vmpools/example.img,OS类型：Linux，版本：CentOS 7.0＆gt; RAM：1024，CPU＆1;＆gt;姓名：示例并保留其余默认值

完成后，我收到以下错误：

Unable to complete install: 'internal error: process exited while connecting to monitor: 2016-08-18T09:29:23.423006Z qemu-kvm: -drive file=/home/vmpools/SureCollectGateway.img,if=none,id=drive-virtio-disk0,format=qed: could not open disk image /home/vmpools/SureCollectGateway.img: Driver 'qed' is not whitelisted
'

但是我可以用ISO创建新的VM。

我如何处理白色列表qed或我缺少什么才能使这项工作？

CentOS不支持qed磁盘格式，请改用qcow2。

https://bugs.centos.org/view.php?id=8986
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/7.0_Release_Notes/Known-Issues-Virtualization.html

qemu-kvm组件，BZ＃731570 红帽企业版Linux 7不支持KVM来宾虚拟机的QEMU增强磁盘格式（QED）。使用qcow2映像而是格式化。

KVM - Drive＆＃39; qed＆＃39;未列入白名单
