   I'm so proud! #Sennheiser never would have allowed a #garage-built #proton-pack to make it in to their behind-the-scenes video! (That's me starting at 2:36)

   For contrast, don't miss the Sennheiser #Spectera video.

   I'm doing the next generation protonpack #fpga telemetry system as an #opensource #openhardware design.

   Team #mastodon will help me out, right?

     Random reader suggestion: try landing your public SSH key using cloud-init, then finish the VM setup using Ansible. You said virsh works to get the IP, and I don't have a better solution. For local VMs, that's what I would do anyway (for my bare metal I set static DHCP, and for my Proxmox VMs I just look at the console).

     I'd love your critique of my approach. (Yes you, random reader!)

     This is a holy grail that I've searched for numerous times. I started on windows (10+ years ago) and the ability to automate was abysmal.

     It's much nicer now with cloud images, virt-installer, python and linux. I decided to do it and within a few days on-and-off it is running fully automated.

     How are other people doing this? (I suspect for most project the answer is they are not.)

     Are there things in this script that can be eliminated?

     Can virt-install be set to wait till the install is done and the vm is ready and return a pass/fail?

     I don't like polling with 'virsh domifaddr' to find the IP address, but it works. How do other people get the IP address of a newly created VM?

     I don't like polling a log file for a string match to wait for completion of cloud-init to avoid potential race conditions. How do people know their VM's are actually running?

     I have five lines of bash to set-up ssh keys. At least they are easy to understand. Is this normal practice?
     I could use #ansible for this, but that creates another dependency. Is that what people do?

     I don't want to argue about the safety of wget, github or |bash. You can't argue that it's effective. How do _you_ solve this chicken-vs-egg problem?

     Just pushed some updates. I have posted the #verilog serial link code. This involved getting a set of scripts for simulation set up.

     If anybody is interested in helping on this project, I'd love to have somebody try to follow the readme.md to install the prerequisites and run the ./run_sim script.

     The goal would be to take notes and flesh out what things aren't in the prerequisite list and how to install them.

     I'd be happy to do the same for somebody else's project.

     This runs in 2m:24s on my machine. Who can run it to confirm it works "not on my machine?"

     This week I went meta: tested the installer of the test sim of the telemetry used to test the product. I'll call that a test-test test.

     I now have one automated script.

     completely means:
     * create vm from scratch
     * ssh keys in both directions
     * apt dependencies
     * mount non-apt bits from host
     + vivado
     + cvc64
     * self checking sim

     @badnetmask Thanks, no-longer-random reader!
     I do use cloud-init to set up the ssh keys to get in to the vm. But I'm trying to have the vm then load sshfs mounts from the host. For that I need to put the vm keys back on the host. I did not see a way to do this via cloud-init. Even if it had that capability it would seem like 'feature creep.' That goes beyond 'init' doesn't it?

     I just learned about virsh and wish I had known of it earlier. It works. Just looking to find out what others do.

     @poleguy
     If your VM will always be local, and you need access to a directory in the hos file system, then sshfs is overkill. Try this instead:
