Ubuntu KVM VM low Refresh Rate GUI

[SAMARJAYEE (Samarjayee Paul)]

Above screenshot is the Graphics properties of the underlying physical host of the VM.

The VM template has been created using Opennebula Ubuntu 20.04 marketplace Public Image.

Inside the VM the Graphics properties are showing, as Cirrus Logic GD 5446

The real issue is, I have installed KDE Plasma for GUI, but the refresh rate is very low. Just to scroll down a webpage the glitch is very high.

The VM is powered by a very high Intel Xenon CPU and Ram. So resource is not a problem.

Can anyone please help to make the desktop experience smoother?

How to enable qxl paravirtual graphic card when selecting VNC

Hi, I would like to know if it is possible to enable qxl paravirtual graphic card when selecting VNC for KVM VMs. I see that is the default option for spice on /etc/one/vmm_exec/vmm_exec_kvm.conf file but I would like to know if there is a way also to make it the default option for VNC or a workaround to make it possible. Thanks in advance, Esteban

There is a way to change the VGA adapter, but xRDP really slow. It seems like the problem is with xRDP.
