CloudXR Runtime 6.0.2 issues in Omniverse Kit 109, AVP, Windows

Hi, I’m working on upgrading our kit app that streams Omniverse content to Apple Vision Pro from kit 106 to kit 109 and have some issues getting the CloudXR / OpenXR runtime working.

Idk if there is any recent guide available on what exactly we’re supposed to do, in kit 106.5 the runtime was integrated to the Omniverse extensions but apparently not anymore.

I found the just today released 6.0.2 version of the CloudXR runtime on NGC and downloaded it, and I’m trying to put the openxr_cloudxr.json there as the custom OpenXR runtime in Omniverse XR Experience or whatever the extension is called in the latest version, just appears as “XR” tab.

On attempting to “Start XR” I get the following error:

2026-01-14T14:28:27Z [604,605ms] [Error] [omni.kit.xr.ui.window.viewport.xr_components.xr_viewport_layer_component] Failed to activate OpenXR: XR_ERROR_RUNTIME_FAILURE
ERROR [ipc_connect_pipe] Connect to \.\pipe/tmp/ipc_cloudxr failed: 2 The system cannot find the file specified.

ERROR [ipc_client_connection_init] Failed to connect to monado service process

Please make sure that the service process is running

It is called “monado-service”

In build trees, it is located “build-dir/src/xrt/targets/service/monado-service”


Error [GENERAL | xrCreateInstance | OpenXR-Loader] : LoaderInstance::CreateInstance chained CreateInstance call failed
Error [GENERAL | xrCreateInstance | OpenXR-Loader] : xrCreateInstance failed

I’ve also got some old (kit 105 maybs or 106.0) version of the runtime which does have a “cloudxr-service.exe” inside it that Iirc had to be running in the background. However the 6.0.2 zip just has the DLLs and stuff inside, no executable. Also no README to explain anything…

Any guidance or pointers to up-to-date documentation on how to run XR in kit 109 would be much appreciated.

Okay, I think I got it running now by tinkering with the CloudXR Stream Manager also available in NGC, but my AVP app doesn’t connect. I probably need to update the client library to matching version and do some refactoring in the app to get it to work.

Is there plans to integrate the runtime to the XR experience again somehow or into the avp bundle extension or something? Setting up the runtime is way too much hassle for our users who just want to hit Start XR and be able to use the app.

@juho.kostet How were you able to get it working? I set the value of the StreamManager pipe to what OV is expecting. When I click “Start XR”, OV just hangs.

Curious about this too, @Richard3D do you know if there’s been changes to how you’re supposed to connect to this headset in Kit 109? I can’t find any updated instructions for Apple Vision Pro.

As far as I know there should be no difference in how we do streaming to AVP. It’s the same set of extensions. But for my help you need to be posting in the correct forum area. In Omniverse > Core Platform
