Orbit exits when selecting the capture tab in a HyperV VM about orbit

[DanOlivier]

I had the very same thing happen to me, under (probably) different circumstances.
Switching to the capture tab initializes OpenGL for the 1st time.

I'm running Orbit on a Windows Laptop (Dell XPS 13, with an Intel HD 520 graphics card) over a kind of "docking station" (Displaylink D3100), which allows me to extend the desktop, or clones the display, over to a larger screen. If I launch Orbit when using this device, I would get a failure, where a call to glGetString(GL_VERSION) was returning "1.1" (I think), an ancient version with no capabilities.

The failure occurs here:

So it turns out that the Dell version of Intel drivers lag behind the Intel versions, and upgrading them yielded better results. The call to getString now returns "4.5.0 - Build 22.20.16.4815", but unfortunately, this doesn't entirely resolve my problem (but that is another matter).

Check your display drivers, and try to run the glew utilities (glewinfo and visualinfo).

I can confirm that the VM's OpenGL capabilities are limited to OpenGL 1.1. Does Qt provide a software renderer that can be used in these circumstances?

From the docs:

The Qt OpenGL module is implemented as a platform-independent Qt/C++ wrapper around the platform-dependent GLX (version 1.3 or later), WGL, or AGL C APIs. Although the basic functionality provided is very similar to Mark Kilgard's GLUT library, applications using the Qt OpenGL module can take advantage of the whole Qt API for non-OpenGL-specific GUI functionality.

So it's just a wrapper.
Glew will not initialize (within your virtualized environment) without greater capabilities.

It looks like RemoteFX vGPU would be required, and that might require a Windows Server (not just Professional)... though I'm going out on a limb here...

As a workaround, you could consider the following: Orbit can be used to profile a process running on another machine. (I have never tried it in a VM but it should work). The matching .pdb files need to be accessible from the Host machine for Orbit to run properly. Make sure you add the proper directories in OrbitProfiler\config\Symbols.txt so that Orbit knows where to find symbols. Orbit will make sure that the symbols on the host match the modules on the target machine.

On the target side, inject Orbit.dll in the target application from a temporary instance of Orbit.exe running on the target machine (Orbit needs to be installed on both machines). The host machine will run the UI version of Orbit while the target machine will use the command line version of Orbit to inject the dll into the target process. Orbit.exe will then terminate on the target machine.

On the target machine’s command line, run:

"Orbit.exe inject:MyProcess host:192.168.0.1" (with the ip of the host machine...)

Orbit will find the first process matching the name “MyProcess” and inject Orbit.dll.

Another option is to control the loading of Orbit.dll from your code. Include "Orbit.h" in your project and call OrbitAPI::Connect with the IP of the machine running the Orbit UI (a_Host) and the port to connect to (a_Port). Note that the Orbit API is header-only, simply add Orbit.h to your project, no lib required.

From Orbit.h:
//-----------------------------------------------------------------------------
struct OrbitAPI
{
static inline bool Connect( const char* a_Host, int a_Port = 1789 );
static inline bool IsConnected();
…
};

Sampling profiling is disabled when remote debugging, it has not yet been implemented. It's on my todo list.
