Description

Motivation

Explore usage of VMWare's VNC-over-websockets API, e.g. to determine whether we need PNG support.

Acceptance criteria

  • AC1: Have a Perl script using os-autoinst's VNC module connect to a VMWare 7.0 VM
  • AC2: Steps to have a mergable solution are documented

Suggestions

  • See parent ticket for more information about VMWare's VNC-over-websockets API
  • Create a Perl script using os-autoinst's VNC module plus some additional code to handle VMWare's API

We should now prioritize the work on this timeboxed ticket to make sure we know about the feasibility of the integration. I bumped the ticket to high after a discussion with QE PrjMgr jstehlik and we found that we should soon find an answer to know where we need to continue or where others, e.g. the QE virtualization squad, need to continue.

No, nobody has looked into it for a while. I have only done the research task (see #106083#note-10 for results). I'm still able to start a VM on https://10.67.131.2/ui/#/host/vms/2 (with credentials from #100688#note-25) so the ticket is still workable. I'll try whether I can make our VNC module connect to it.

PR for a first step: https://github.com/os-autoinst/os-autoinst/pull/2091

Now needs to be integrated with the rest of os-autoinst.

It doesn't work unless I allow JPEG in VNC viewer (which then says "Pixelformat depth 24 (32bpp) little-endian rgb888 wird verwendet"). So we needed to implement JPEG support within our VNC viewer to make it work. However, that might not be very worthwhile because the compression artifacts (which were visible in my tests) screw up the pattern matching algorithm easily. We could still give it a shot. If the screen is still long enough the compression artifacts usually decrease a lot.

Maybe it can also be configured somehow on the VMWare-side.

It actually works with raw encoding as well. I just had to increase the max. size for web socket messages. The performance isn't great, though.

next step: Integration of the workflow into our VNC module

 #12

Updated by mkittler over 2 years ago

I've been updating the draft PR which should now fulfill both ACs of this timeboxed/spike ticket. So we "Have a Perl script using os-autoinst's VNC module connect to a VMWare 7.0 VM" but no integration into the workflow of our VNC module yet. That's something for the next ticket.

However, I must say that I would not get my hopes up that this will be very performant. At least in my tests it was not really usable. Maybe it is due to using VPN from Germany and https://vh002.qa2.suse.asia being supposedly located in China. Additionally, my session also terminated sometimes. I suppose doing some actions over VMWare's web interface can kick one out of the VNC connection. So if we want this to work in some way stable we definitely need to have a good retry behavior (which means requesting a new VNC session from scratch as one websocket URL is only for one-time use anyways). Considering that I would really reconsider whether you must use VMWare (in that way).

The next steps to continue (if we must) are outlined in the commit message (see https://github.com/os-autoinst/os-autoinst/pull/2091/commits).
