Has anyone been able to get FreeRDP's Thincast Workstation (based on VirtualBox) product to work?

I know it's still in beta, but it was originally released two years ago and I'm still not able to boot ubuntu's mini.iso installation media in this graphics-optimized version of VirtualBox.

If anyone has been able to test Thincast workstation performance, can they compare it to a Hyper-V linux virtual machine connected to X410 through VSOCK:
