<p>Just to follow up. I tried VMware Workstation 16 Player on
Windows 10 (free for non-commercial use), and ran Ubuntu 20.04 in
it. And I was able to run ChimeraX in the virtual machine after I
enabled "3D graphics" in the Display settings. I also increased
the amount of graphics memory allocated, but it is unclear if that
was necessary. The host machine is running Windows 10 with an
NVidia GeForce GTX 970 and the latest graphics driver. So there
exists at least one virtual machine product that can do OpenGL 3.3
(4.1 in my case) if the host is powerful enough.<br>

<p>Whether or not you can update your virtual machine to OpenGL
3.3 depends if your virtual machine supports it or not -- that
is, it is a (virtual) hardware problem, not a software problem.
For example, with Oracle VirtualBox on Windows, it is not
possible at this time. I don't have experience with other
virtual machine software to know which ones support OpenGL 3.3.
If they do, the OpenGL provided by the host operating system
would need to be OpenGL 3.3 or higher, and the virtual machine
would need to configured to use the host's OpenGL.</p>
<p>If you do find a virtual machine that supports OpenGL 3.3,
please let us know. As please remember, ChimeraX's performance
will be lower when running in a virtual machine. If you can
view the data with a native version of ChimeraX, you'll be much
happier.</p>
<p> Good luck,</p>
