根据引用[1],要列出指定计算节点的虚拟机,可以使用命令`nova hypervisor-servers <节点名称>`。这个命令将会返回指定计算节点上的虚拟机列表。
以下是一个示例:
```shell
nova hypervisor-servers compute-node-1
```
这个命令将会返回compute-node-1节点上的虚拟机列表。

docker desktop - windows hypervisor is not
Docker Desktop for Windows requires the Windows Hypervisor Platform (WHPX) to be enabled in order to run properly. To enable the Windows Hypervisor Platform, you can follow these steps:
1. Open the Control Panel and navigate to "Programs" and then "Turn Windows features on or off".
2. Check the box next to "Hyper-V" and click "OK" to enable the feature.
Alternatively, if you prefer using a command-line approach, you can create a new text file on your desktop and change its extension to ".bat" or ".cmd". Then, copy and paste the following code into the file:
```
pushd "%~dp0"
dir /b %SystemRoot%\servicing\Packages\*Hyper-V*.mum > hyper-v.txt
for /f %%i in ('findstr /i . hyper-v.txt 2^>nul') do dism /online /norestart /add-package:"%SystemRoot%\servicing\Packages\%%i"
del hyper-v.txt
Dism /online /enable-feature /featurename:Microsoft-Hyper-V-All /LimitAccess /ALL
```
Save the file and double-click it to run the script. This will enable the necessary Hyper-V components for Docker Desktop on your Windows system.
After enabling the Windows Hypervisor Platform, you should be able to run Docker Desktop without encountering the "docker desktop - windows hypervisor is not found" error.
hypervisor
Hypervisor是一种虚拟化技术,可以将物理硬件划分为多个虚拟机,每个虚拟机可以运行独立的操作系统和应用程序。根据类型的不同,Hypervisor可以分为两类。第一类是类型1 Hypervisor,它直接运行在物理硬件之上,例如基于内核的虚拟机(KVM)。第二类是类型2 Hypervisor,它运行在另一个操作系统中,例如QEMU和WINE。在Hypervisor的发展过程中,它已经成为一个新的战场,而Linux在其中扮演着重要的角色。市场上也有许多第三方管理和自动化产品可以用于裸机虚拟化Hypervisor的管理,但是裸机Hypervisor的成本较高。大多数裸机虚拟化Hypervisor宣称是免费的,但是仅限于核心Hypervisor的功能,而基于主机的Hypervisor则可以免费或者只需花费数百美元来扩展其功能和可扩展性。[1][2][3]
