Hi Uri

Thanks for your reply and your notes is right only that 

Vw is wrong spell. I means vm for virtual machine.

 I have deploy the streaming agent and I will try h264.

4k vdieo is one of requirements of our project.

So pls help us with this.

best wishs

Hi :

I am a phd student of Xian Jiaotong university in China.

We have a project to accomplish a remote-desk solution with Nvidia vgpu.

We use spice latest version  and have a bad 4K display quality.

Our environment is like:

1.T4 card with inspure server in nvidia support list

NVIDIA Tesla T4  GPU card

2.redhat 8.2 enterprise  with kvm qemu

 

3.vgpu software package is 13.x

NVIDIA driver + tools (GRID)

 

4.vw flavor is 8u 16G. with 40 storage.   vgpu license is vpc ,and vgpu is B-2b.

"vw" == Virtual Workstation

B-2b is the vGPU type? meaning T4-2B ?

Does it help if you configure it with T4-2Q (may require a different license)?

Only a single Display, right ?

Are you running spice-streaming-agent on the guest ?

Try to stream with H264, if you do not already do it

(may require paying fees for using H264).

Is 4k resolution a requirement? If not, try with e.g. 2k.

Hope that helps,

    Uri

 

And our issue is attached in appendix.

Please give us some help to solve this.

best wishs;
