7.18.7.3. 通过 CLI 从快照中恢复虚拟机
您可以使用虚拟机快照将现有虚拟机（VM）恢复到以前的配置。
先决条件
-
安装 OpenShift CLI（
oc）。 - 关闭您要恢复到之前状态的虚拟机。
流程
创建一个 YAML 文件来定义
VirtualMachineRestore对象，它指定您要恢复的虚拟机的名称以及要用作源的快照名称。例如：
apiVersion: snapshot.kubevirt.io/v1alpha1 kind: VirtualMachineRestore metadata: name: my-vmrestore 1 spec: target: apiGroup: kubevirt.io kind: VirtualMachine name: my-vm 2 virtualMachineSnapshotName: my-vmsnapshot 3
创建
VirtualMachineRestore资源。快照控制器更新了VirtualMachineRestore对象的 status 字段，并将现有虚拟机配置替换为快照内容。$ oc create -f <my-vmrestore>.yaml
验证
验证虚拟机是否已恢复到快照代表的以前的状态。
complete标志需要被设置为true。$ oc get vmrestore <my-vmrestore>
输出示例
