I love the simplicity of the solution.

Is ustreamer what the nanokvm uses?

Follow up idea: we should document somewhere our list of drivers, and the required dependencies (even where to find them i.e. there is no ustreamer for centos or rhel, but we could easily build it somewhere in copr from the fedora packages).

No, ustreamer is from the pikvm project. While nanokvm creates their own jpg_stream for utilizing the VPU.

Ahh true! ':D

I guess we can eventually create also a driver for jpg_stream :) so we don't need to re-invent a driver for the nanokvm, we use the provided one :)
