Does Docker Use Qemu How To Run Accelerated

You can edit basic.sh further to straighten these out, but the VM still booted with these errors present.

Does Docker Use Qemu How To Run Accelerated

Then I realised, I finally had an excuse to give this a go Ive been itching to since I read - Accelerated KVM guests on WSL 2, an awesome write-up on how to run accelerated KVM guests on WSL2 from unixterminal.

I am still stunned how good the performance is having run through this Ive tried a couple of other Linux distros too, seriously slick.

One thing thats not obvious is your CPU needs to support virtualisation.

Unless youre running an Intel CPU from the early 2000s or even earlier you should be OK.

If youre already running a hypervisor, its likely this is good to go.

The insiders Fast ring which is mentioned in the pre-requisites is now the Dev channel.

One of the features required didnt come into Windows 10 until build 19619 and the nested virtualisation support for AMD didnt come in until build 19636 either, so thats a must if you are on AMD too.

The windows insider page currently lists 19042.423 as the highest build available in Beta and 19041.423 as Release Preview, so for the moment this will not work correctly without using the Dev channel.

Dev channel is described as Ideal for highly technical users.

Insiders in the Dev Channel will receive builds that is earliest in a development cycle and will contain the latest work-in-progress code from our engineers.

These builds will have rough edges and some instability that could block key activities or require workarounds.

Having traced back through the steps it was time for a search which yielded an issue from the WSL github repo.

So reverting back to the step Install your kernel in WSL 2 and enable nested KVM the.wslconfig was changed to.

I left it in for a while in case I needed to troubleshoot further.

Therefore, I went for X410 which is 9ish in the Microsoft store, but as Im planning to use this until GUI support comes out later in the year, it was worth the price for the easy setup.

If you keep following the post at this point youll set up an Ubuntu 20.10 daily build.

I ran through this as a check to see if everything was working, the steps for this were exactly the same as in the post.

It is described as set up a simple macOS VM in QEMU, accelerated by KVM.

If you ran through setting up the Ubuntu 20.10 daily build in step 4 youll already have seen QEMU being mentioned.

You might be thinking, why are there two types of virtualization technologies The key part is in how KVM and QEMU differ, which is summed up nicely in this post.

KVM uses the CPU virtualization extensions for Intel and AMD, and QEMU is performing the virtual hardware emulation, or to put it another way, KVM is QEMUs go faster stripes.

First clone the git repo in, make sure to use the linux filesystem as it is faster at the moment on wsl2 than windows (mnt).

If it isnt running when you run basic.sh in this next step itll have for a minute or so then fail.

The box in green are errors related to sound, Im not so worried about those, and explain my sound related issues with Ubuntu above.
