If you are interested to test Android on QEMU
with 3D hardware acceleration (via virgl, of course),
here is an ISO you can test:


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

Android-x86 project
