update to 7.2, to use VirGL

I was able to make it work without installing the GPU drivers on the host. Now I'm trying to install it, I'm receiving some errors but I'll continue trying.

One thing that I would like to mention is when I selected VirGL GPU the performance was not good and the audio/video was lagging. Then I selected the option VirtIO-GPU and now it is working very well using SPICE, the video/audio is smooth.
 
Update: I was able to install the Nvidia drivers on the host, and it is working fine. I'm using VNC to connect to Ubuntu VMs, I tried xrdp but it is lagging.
 
Running ` nvidia-smi` on my host machine shows that using VirtIO-GPU my GPU was not being used by the guest VM. After changing it to `VirGL-GPU` , my VM shows up on ` nvidia-smi` output, and now it is not legging anymore, maybe because I installed the Nvidia drivers on the host?
