Hello everyone !

I was compile Qemu with Libvirt in Debian.
This two application was compile with success, but with a some warnings.
I have 2 GPU devices.
Actually I want connect 1 GPU for Windows and 2 GPU for Linux Debian.
I would like add 2 GPU/Windows for inside Linux.

I have a some troubles with all process.
My second GPU/Windows has errors, when I run Qemu.

Example:

Code:
No provider of glEGLImageTargetTexture2DOES found

I have got error too:

Code:
cannot execute binary /usr/local/bin/qemu-system-x86_64: Permission denied.
I haven't get myself why.


I have this now:
  1. Debian 10.5
  2. Qemu 5.1.0
  3. Libvirt 6.6.0


Any help/idea ?

Does anyone has knowledge Qemu needs two mouses and two keyboards ?

Does Qemu needs 2 GPU's / 2 monitors ?

How it should works ?

When I run Qemu I was black screen and do nothing.

I can turn on full screen, but without result.
Sometimes this process was automatic exit and goes system turn on.

Then I must kill this process.

Any idea ?

I will answer your second post first.
No, Qemu and KVM do not require separate keyboards or monitors.

I'm not sure how you have this implemented, but you will need to learn/run virsh commands in order
to create/run VMs. You will need to load an ISO file of some OS.

You will have to have virtual networking enabled to do this.

==================================================

Why are you compiling this? Why not just install and run the Debian package?

Permission denied means you are trying to run a system process, rather than a user process.
You will need root password or else sudo to run this command.

What desktop GUI environment are you running?

Thank you very much for answer!

Why am I compiled Libvirt and Qemu ?
I fight with this 2 application for a few years.
I want to have 1 GPU for render in second/inside of my system Debian.

I use/work in Blender 3D app. I'd like to get Windows system for a some possibility.

Qemu and Libvirt are works without adding this additional second GPU.

All the time don't works for me the passthrough GPU.
I don't understand this passthrough.

I was searching this problems in Network, but without results.

I try run Qemu with this passthrough GPU, but my all the system was crashed.

I have XFCE - Debian.

When I run Qemu with Libvirt and all the process with set option "Render" Qemu was turn off.
Sometimes when I run Qemu has black screen and do nothing.

You can get a long way with qemu/kvm by using virt-manager, and you can also use it on remote systems using X11 forwarding. But for complicated things being able to use virsh is easier or at least know the basics and the rest you will be able to find your way from documentation on the internet.
