I set up a machine with AMD Threadripper 2950 , motherboard GIGABYTE Aorus xtreme and WX7100 GPU. I'm running Fedora 29 at the moment ( tested ubuntu 18.04 and Tumbleweed as well). The machine performance is awesome , However there is very weird system response on virtualisation performance. tried KVM QEMU and Boxes. It it literally impossible to use any graphical work on guest machine.
Even in very normal workloard, ( I have set 4 cpu cores, 8GB RAM on KVM ), the guest cpu load is nearly %90 in total, and 3.5GB of allocated RAM and used 1.5MB of swap! This makes my virtaul machine very slow and laggy.
I'm wondering if anyone have experienced such an issue and if you can advise who I can fix this issue?

linux-kvm.org/page/Tuning_KVM - for "graphical work" you should elaborate (what are you trying to do and how is it configured). Virtualization is a wide field (ranges from archaic hardware over server only to full blown gpu-passthrough-gaming) and it's unclear what you're asking about specifically...

Graphical work is not the entire reason for using KVM. I need a specific set of hardware development run on different Linux virtual machine. I did set standard installation of KVM/QEMU. Had some difficulties on spice server and OpenGL setup. However, graphics rendering is not good at all on VM ( Centos 7.5 now ). I've been heard that I cannot use GPU passthrough and share GPU RAM between several KVM VMs, if that so, I prefer to have several VMs on a good performance and run all in the same time for my application if I can.
