See if this Gentoo website on VM help narrow your problem with your GPU cards: GPU passthrough with libvirt qemu kvm - Gentoo Wiki 

Otherwise, AMD Resident expert on Professional GPU Cards may be able to help you with your problem fsadough‌

Thanks for you reply .
My problem is that S7150 can passthrough into VM and work, but S7150v cant .

[elstaci]

Okay, maybe FSADOUGH can be of assistance or someone with experience with Linux VM can offer something.

Good luck!

Maybe the right approach is not vnc,spice but rdp.
