Hi,
It seems upstream Linux/Gallium3D/Mesa/Qemu/KVM has recently gained
virtualized support for 3D/OpenGL hardware acceleration in VMs,
allowing using the GPU of the host in VMs.
As per my understanding the following components are needed -
- Linux 4.4 kernel includes the DRM driver for VirtIO-GPU 3D
acceleration (needed in the VM).
- Qemu 2.5 includes the VirtIO-GPU 3D mode support.
- Gallium3D VirGL driver is included in Mesa git (needed in the VM,
supports up to OpenGL 3.3 atm).
- On the host *any* OpenGL driver (for the host GPU obviously), no
special requirements there.
In order to do test this, if I can be guided as to what are the right
applications to test the entire Graphic stack on a QEMU-KVM Virtual
machine, I shall be grateful.
Regards,
Saket Sinha

In qemu 2.5 only gtk3 frontend support 3D and must be enabled with gl=on

glxinfo in the guest should print virgl in the renderer string, that is enough
to know the stack is functioning.
if it shows llvmpipe it isn't.

If you are interested to test Android on QEMU
with 3D hardware acceleration (via virgl, of course),
here is an ISO you can test:
http://www.fosshub.com/Android-x86.html/android-x86-6.0-20160318.iso
The command to run QEMU
qemu-kvm -smp 2 -m 2048 \
-device virtio-gpu-pci,virgl -display gtk,gl=on \
-d guest_errors \
-serial mon:stdio \
-cdrom android-x86-6.0-20160318.iso
It's built with kernel 4.4.4 and Mesa 11.2.0-rc3.
If you'd like to build the ISO yourself, please read
https://sourceforge.net/p/android-x86/wiki/Downloading%20and%20Building/
