I write because I have a problem with houdini 15.5.523

In my computer I have the Graphical card: Nvidia Geoforce GT 630M

I created a virtual machine (virtual box) and installed ubuntu 14.04., then houdini 15.5.523. apprentice version.

When a I try to create a polygon I have this error:

Crash report from joe; Houdini Version 15.5.523

What is the problem?

Thank you

Did you find a solution? I get a similar error before Houdini starts, right after the splash screen.
