![]() Therefore, it is necessary to enable this function only when using WSL2 or Hyper-V while also using VirtualBox or Android emulator (VM acceleration). To get around that, it published something like an additional API for the Hyper-V hypervisor, and VirtualBox and Android emulators made virtualization aids available through that API. As a result, there were previously problems such as the Oracle VirtualBox VM not being able to start or the HAXM that the Android emulator used for VM acceleration could not be installed. When the Hyper-V architecture is enabled, the Hyper-V hypervisor occupies CPU-based virtualization aids such as Intel VT-x. So, what is it for, but simply put, it is "a mechanism for running things like WSL2 and Hyper-V (that is, situations where the Hyper-V architecture is valid) as well as Oracle VirtualBox 6, Android emulators, etc." This is a very confusing name, but if you're just using the Hyper-V architecture, you don't need to enable this feature. If you run hcsdiag list with administrator privileges while running WSL2, you can confirm that it is started as a container called "WSL". However, in order to run Windows binaries in a container, the "container" function described later is also required.Īlso, although there isn't much decent documentation, containers instantiated on this virtual machine platform can be listed, for example, with the hcsdiag.exe command. This is to support "process isolation" and "Hyper-V isolation" required to create highly independent containers on Windows2. ![]() The service is referred to in English as Host Compute Service (HCS), and the official documentation can be found around here. When enabled, a Windows service called Hyper-V Host Computing Services also runs. ![]() The core of Windows 10's container functionality utilizing the Hyper-V hypervisor. ![]() (2020/8 update) It is said that you can change and confirm the setting by bcdedit command. An image that is enabled when any of the features that require a hypervisor are enabled. However, it is not possible to set enable/disable by itself. Overview of Windows 10 features related to Hyper-V by edition Windows 10 Home Hyper-V architecture (Hyper-V hypervisors and Hyper-V networks) This feature can be enabled on all editions, including Windows 10 Home, as stated in the MS FAQ. The "virtual machine platform" mentioned here should be enabled in "Enabling or disabling Windows features," as described in the "Installing WSL" article on Day 1. The closer you are to the WSL 2 release, the sooner you can see the details of this experience. This optional component is available on all SKUs. This architecture is available in the optional component of Virtual Machine Platform. The latest version of WSL enables virtualization using the Hyper-V architecture. WSL 2 is available in all SKUs where WSL is currently available, including Windows 10 Home. Quote from MS FAQ Does WSL 2 use Hyper-V? Will it be available in Windows 10 Home? They are also available in Windows 10 Home, so you don't need a Pro in WSL2. WSL2 is built on top of the Hyper-V architecture, which is the core functionality of Hyper-V, and the Hyper-V containers that take advantage of it. Please also note points when installing and using WSL2. We made WSL Advent Calendar again in 2020.
