Screen-recording of VM session

It would be very useful if it were possible to screen-record a tart session to a file.

In my particular case, I have a packer build which seems to be behaving different in CI as opposed to locally. It is quite tedious to only be able to watch a build as it happens. I have to time it just right, port forward the VNC port over SSH, then connect with my VNC client.

Alternatively, it would be handy if I could specify VNC port and password when using --vnc-experimental so that I could have a fully automated/scripted flow to connect to a live build.

That is a very interesting idea! Seems it can be nicely integrated into the packer plugin given availability of VNC. At the very least we can take screenshots every second and then use a locally installed ffmpeg to create the video.

Writing to a file would be great. We've looked at using opencv to handle some automation and error detection. This would greatly simplify those efforts.
