Ubuntu 22.04主机VirtualBox中Windows 10虚拟机安装WSL2报错0x80370102的求助

大家好，我遇到了一个WSL2安装的问题，想请教下各位：

我的环境是Ubuntu 22.04作为主机，用VirtualBox运行一个Windows 10虚拟机。因为实在不习惯Cmd和PowerShell，只想在Win10虚拟机里装个WSL2来用Bash终端。

按照WSL的安装步骤操作后，看起来好像安装成功了，但打开Windows Terminal里的Bash标签时，却弹出了这个错误：

Installing, this may take a few minutes...
WslRegisterDistribution failed with error: 0x80370102
Please enable the Virtual Machine Platform Windows feature and ensure virtualization is enabled in the BIOS.
Press any key to continue...
[process exited with code 1 (0x00000001)]

错误详情里明确提示：

Error: 0x80370102 The virtual machine could not be started because a required feature is not installed.
Please enable the Virtual Machine Platform Windows feature and ensure virtualization is enabled in the BIOS.

我查了相关排障内容，里面提到如果是在虚拟机里运行的话，需要手动启用嵌套虚拟化，步骤是用管理员身份打开PowerShell，运行这条命令：

Set-VMProcessor -VMName Windows10 -ExposeVirtualizationExtensions $true

但我在Win10虚拟机里的管理员PowerShell中运行这条命令时，却得到了报错：

Set-VMProcessor : The term 'Set-VMProcessor' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
At line:1 char:1

• Set-VMProcessor -VMName Windows10 -ExposeVirtualizationExtensions $tr ...
• CategoryInfo : ObjectNotFound: (Set-VMProcessor:String) [], CommandNotFoundException
• FullyQualifiedErrorId : CommandNotFoundException

我在VirtualBox的GUI里看到这个虚拟机的名称确实是Windows10，难道名称不对吗？另外，我是不是应该在主机的Ubuntu系统里做些什么操作？还有，我已经进入BIOS确认过AMD-V虚拟化是开启状态的。

请问各位还有什么其他可以尝试的解决办法吗？
