CMR*_*CMR 4 vmware-vcenter vmware-vsphere
我们有 2 个独立的 VMWare 环境,一个是主环境,它在许多站点上拥有数百个虚拟机。另一个是安装在一台服务器上的小得多的,仅用于归档旧系统。
我想要做的是拍摄我们一个实时 VM 的当前状态的快照,并使用它复制到另一个 VMWare 环境并在那里创建一台新机器,将其用作该系统的存档。
这可能/容易吗?
该死,如果您一直在使用 vSphere 6,您就可以完成 vCenter 间的克隆并完成它。
无论如何,如果您使用 PowerCLI,这项任务对于 5.5 来说也不是非常困难。
步骤如下:
使用 PowerCLI 这个方便的一点点将快照克隆到新的 VM:
New-VM -Name $CloneName -VM $SourceVM -Location $CloneFolder -Datastore $Datastore -ResourcePool $ResourcePool -VMHost $VMHost -LinkedClone -ReferenceSnapshot $Snapshot
您可以在此处查看所有选项的含义以及如何填充它们。
他们的关键是“-ReferenceSnapshot”选项。
将您的新虚拟机导出到 OVF/OVA,或将文件夹从 DS 复制到网络上的某个位置
我让我的 IT 安全团队要求一份正在运行的 VM 的“取证”副本,包括内存快照,这样他们就可以在出现病毒或某种破坏的情况下进行一些调查。为了让我的生活更轻松,我编写了一个 PS 函数来完成所有繁重的工作。它只需要一个源虚拟机(按名称或对象)和磁盘上的文件夹。它完成其余的工作。
