我正在创建一个PowerShell脚本作为计划任务运行。它的目的是每周一在我们的每台虚拟机上创建一个快照。我为每个VM创建了一个简短的脚本。建立到本地Hyper-V服务器的远程会话后,它应该只需找到我们的虚拟机并创建一个快照。这是测试时的样子:
"jest": {
"preset": "react-native",
"testEnvironment": "jsdom"
}
正如您可能知道的那样,当我手动运行" get-vm"时,远程计算机就好了。但是当作为脚本运行时,它仍然会搜索我的工作站。以下是脚本的内容:

我添加了start-sleep命令作为尝试修复,认为命令在建立连接之前被触发。没有这样的运气。踢球者是如果我逐行完成这个脚本,它的工作正常。任何帮助表示赞赏。编辑:当完整地粘贴脚本的内容时,它也是完美的。

Enter-PSSession
仅用于交互式会话,因此以交互方式工作或粘贴到会话中确实有效,但不是在本质上不是交互式的脚本中。
你可以
-ComputerName
Get-VMSnapShot
参数
正如您自己发现的,使用过的cmdlet必须与Hyper-Vserver版本匹配。
