Error QEMU

[SauloVR91]

Hello. I'm trying to install on the orange pi 3b. Running casaOs. But it is showing the following error:

windows | ❯ Starting Windows for Docker v1.10... windows | ❯ For support visit https://github.com/dockur/windows-arm windows | windows | ❯ ERROR: KVM acceleration not available (device file missing), this will cause a major loss of performance. windows | ❯ ERROR: See the FAQ on how to enable it, or continue without KVM by setting KVM=N (not recommended).

This error occurs after unzipping the windows11 image. Previously, I tried to install the x64 version (I thought it was this version) and it just shows great slowness, but Windows actually goes to the installation part.

I ran sudo kvm-ok and it showed no errors.

Seems like the device /dev/kvm is missing from your compose file. Can you show me your run command or compose file?

[SauloVR91]

I used the default installation.

version: "3" services: windows: container_name: windows image: dockurr/windows-arm environment: VERSION: "win11" devices:

• /dev/kvm cap_add:
• NET_ADMIN ports:
• 8006:8006
• 3389:3389/tcp
• 3389:3389/udp stop_grace_period: 2m restart: on-failure

[kroese]

Strange.. Try adding privileged: true

[SauloVR91]

I tried with administrator but it didn't work either. There is a difference in the location I am using, which is the storage, due to the storage space on the main unit. The drive I'm using is using ext4 format.

[kroese]

It says /dev/kvm is missing, so it cannot be related to storage. Can you try if it makes a difference if you run the CLI command (with sudo in front) instead of the compose file?

[SauloVR91]

Same error, I ran the code below.

sudo docker run -it --rm --name windows -p 8006:8006 --device=/dev/kvm --cap-add NET_ADMIN --stop-timeout 120 -v /media/Dados/Windows:/storage dockurr/windows-arm

It freezes at boot time with QEMU

[kroese]

What do you mean exactly by freezing? Do you see the TianoCore logo for example?

[SauloVR91]

No, it's straight like that.

Today I updated the entire package again, running apt install qemu-system. But still the same situation persists.

[kroese]

From the screenshots it looks like your run kvm-ok inside the container. But you should run it on your host. So you might need to SSH into CasaOS for that.

[SauloVR91]

Sorry @kroese. But the result is the same:

Any idea ?

[kroese]

Can you try https://github.com/dockur/windows-arm/issues/37#issuecomment-2099703987 ?

[SauloVR91]

Can you try #37 (comment) ?

i will try.

I fixed this for the Orangi Pi 5 now in v2.10, by adding CPU pinning support to pin it to cores 4,5,6 and 7 when it detects a RK3588 CPU.

I would also like to fix it for the Orange Pi 3 and 4, so if you are still interested can you please show me how this CPU is named in the Docker log when you start the container (the line that shows CPU/RAM/kernel).

Sorry for the delay. Today I managed to carry out tests with the new version. Below is the requested information. In fact, my model's processor is quad core and not octacore.

[kroese]

@SauloVR91 Thanks.. The problem on the OrangePi 4 and 5 was that they had mixed cores (4x A55 and 4x A76 for example). After pinning it to one type it worked.

But I now see that the OrangePi 3B has 4x A55 and no mix of types at all. So your problem is totally unrelated, and after reading it better I see it was about KVM missing.

It will be useless to figure out why you have no display output with KVM disabled, because even when we fix that, Windows will run extremely slow and sluggish without the hardware acceleration KVM provides.

So our only option is to figure out why KVM doesnt work with the Docker on CasaOS.

Can you execute the example docker run command with sudo in front, so: sudo docker run .... and see if it fixes the permission error for KVM?

[SauloVR91]

I ran docker directly from the ubuntu server, outside of CasaOS. This was the result, I'm starting to think that somehow, there isn't a KVM on the orangePi 3B

[kroese]

Can you try if you can run the example compose from: https://github.com/qemus/qemu-arm

Because both projects share 90 percent of the same code. So if that other one runs without problems on your system, we know the issue is related specificly to Windows.
