红帽全球峰会1.3.18. 存储
默认情况下，每个快照每小时无法恢复超过 6 个卷。因此，在 Kubevirt 环境中，通常无法从"折叠的镜像" （作为快照保存的模板）每小时创建超过 6 个虚拟机。
对于 Google Cloud Platform (GCP)持久磁盘(PD)存储 Container Storage Interface (CSI)，现在有一个名为 csi-gce-pd-vsc-images 的非默认 VolumeSnapshotClass，它使用 snapshot-type: images 参数。在使用 KubeVirt 时，它允许您每小时限制克服 6 个虚拟机，以便您可以从"冷镜像"创建虚拟机。
此功能在 OpenShift Container Platform 4.22 中正式发布。
