Ovirt 不创建实时快照

Ovirt 不创建实时快照

我安装了 oVirt。如果我暂停虚拟机并创建快照，那就没问题了，但如果我尝试在“完成”阶段创建实时快照，ovirt 就会失败。Ovirt、VDSM 和 NFS 存储在同一个本地服务器上。

有任何想法吗？

答案1

这是你的答案：http://permalink.gmane.org/gmane.comp.emulators.ovirt.user/2527

您的 qemu 版本较旧，不支持实时快照，您需要较新的版本（1.1 或更高版本）

PS：如果你将来发布你使用的软件包的实际版本，通常会有所帮助

答案2

这是正常现象。您必须暂停虚拟机然后进行快照。
