Texture broken in webgl #7

I installed xengt on my IvyBridge PC and encounter this trouble.

In my Linux DomU, if I run webgl acuarium (https://webglsamples.googlecode.com/hg/aquarium/aquarium.html), the textures all all broken.

I'm not sure if it is because I'm using IvyBridge or a possible bug in xenGT. If it is due to I'm using IvyBridge, I would like to purchase Haswell PC.

BTW, is this kind of trouble can happen in xenGT in theory? I expect there shouldn't be such trouble because xenGT is basically based on pass-through.

No, this should not happen with XenGT. I believe it's caused by unsupported hardware(programming HSW only), and I'm sorry to say that, you will need a HSW desktop for trying xengt/kvmgt :)

Are you using our code drop for Haswell, or the experimental code for BayTrail? If it is the former, as Jike said, you would better change the desktop, since we do not formally support IVB and there is no validation on that.

For this kind of texture problem, one possible reason is the resource limitation, since we only assign part of graphics memory to a VM. One easy way to test is to change option to enlarge both low and high gm memory and try again. Thanks!

I'm using the code with Haswell and I also think that I need HSW PC. Thanks!
