c# - 如何通过 WMI 更改 HyperV 内部虚拟机网络适配器的网关、子网？

Question

大家好，

我的问题是： 1. 如何通过 WMI 和 C# 以编程方式在 hyper-v 中设置虚拟机内部网络适配器的子网掩码、DNS 地址和网关地址？

注意：我可以成功地添加和检索 IP 地址，如此处所述

请帮忙谢谢

史蒂夫

Answer 1

Hyper v 不支持该功能，其公开的 SCVMM 服务没有任何方法可以做到这一点。您必须手动完成。

Answer 2

我一直在寻找同样的东西并碰到了这个，

可以设置 IP 以及子网和网关，但最低要求是，

• Windows 8 [仅限桌面应用程序]
• Windows Server 2012 [仅限桌面应用程序]

Answer 3

如果您使用的是 Server 2012 或更高版本，我会使用 @slayerbot 的链接，但如果您不在 2012 或更高版本上，您可以查看 Win32_NetworkAdapterConfiguration 类的方法。

https://msdn.microsoft.com/en-us/library/aa394217(v=vs.85).aspx#methods

即 Win32_NetworkAdapterConfiguration 的 SetDNSServerSearchOrder EnableStatic 方法。

如果您不更改 IP 地址，我将首先查询当前 IP 地址，然后在“EnableStatic”inParams 中重复使用该地址。

另请注意，您需要知道要更改的 NIC 的索引。
