<p>Hi virgl-guys,</p>
<p>I reported this issue in qemu community a week ago, so far I
can't solve</p>
<p> this problem by myself. thanks Marc for help me to get more
information</p>
<p>about using virtio-gpu. but my environment could not change to
Fedora24</p>
<p>that mentioned in
<a class="moz-txt-link-freetext" href="http://blog.wikichoon.com/2016/05/spice-openglvirgl-acceleration-on.html">http://blog.wikichoon.com/2016/05/spice-openglvirgl-acceleration-on.html</a></p>
<p> to test virtio-gpu. so I hope some one can tell me what's wrong
about my</p>
<p>environment or is this a virgl bug?<br>
</p>
<div class="moz-forward-container">BTW, where can I get a detail
documents about how to build virtio-gpu enviroment?<br>
<br>
<br>
Thanks,<br>
Chen<br>

<pre>Hi all,
I tried to use virtio-gpu to do some test, the glmark2 works, but when I
ran heaven benchmark in Guest,
the application could not be ran. I have collected the output message.
pls see attachment file.
I built my environment according to the requirement in
<a class="moz-txt-link-freetext" href="https://copr.fedorainfracloud.org/coprs/kraxel/virgl/，">https://copr.fedorainfracloud.org/coprs/kraxel/virgl/，</a>
both guest/host kernel version: 4.6
I used the latest qemu forked from master branch
(e00da552a0dc82f4ec7896281eada7201e69f1db),
and run qemu with:
~/data/linux-src/qemu$ ./x86_64-softmmu/qemu-system-x86_64 -vga virtio
-display gtk,gl=on --enable-kvm -m 4000 -smp 4,sockets=1,cores=4 -hda
/home/chenfan/imgs/fedora23.qcow2 -cpu host
when running the heaven benchmark application the qemu has some output
as following, I don't know how to fix that,
do you have some hints? thanks in advance :)
the qemu output messages:
