Extermely slow and laggy

I set up whonix under arch using virtlib, qemu and kvm but it is extremely slow, not in term of network but in term of fluidity, when I open a program it takes a long time to open, everything is slow and unresponsive. I have to add that I had to deactivate accel2d as the virtual machine would refuse t start saying it’s not available. Any idea how to fix this ?

Please follow the instructions to install the qxl-xorg-enhance package:

Awesome that fixed it, ty HulaHoop.
