Does packer support "predictable" network interface names (systemd)?

I'm trying to use the vagrant ubuntu/xenial64 box as my source ovf. Works fine in vagrant, but ssh is never reachable in packer.

2017/07/11 10:56:04 packer: 2017/07/11 10:56:04 [DEBUG] TCP connection to SSH ip/port failed: dial tcp 127.0.0.1:2875: getsockopt: connection refused

packer.json:

{

"variables": {

"home": "{{env `HOME`}}"

},

"builders": [{

"type": "virtualbox-ovf",

"source_path": "{{user `home`}}/.vagrant.d/boxes/ubuntu-VAGRANTSLASH-xenial64/20170705.0.0/virtualbox/box.ovf",

"headless": "true",

"boot_wait": "10s",

"ssh_username": "ubuntu",

"ssh_password": "48a16ff5a87dbd49b28864f6",

"ssh_wait_timeout": "10m",

"shutdown_command": "echo 'vagrant' | sudo -S shutdown -h 0",

"vrdp_bind_address": "0.0.0.0"

}],

"post-processors": [{

"type": "vagrant",

"keep_input_artifact": true,

}]

}

Packer output:

nicholas@pickle:~/dev/chef-akm$ packer build packer.json

virtualbox-ovf output will be in this color.

Packer doesn't do anything with your guest, so it doesn't (need) know anything about NIC naming.

If you post your template, scripts, and kickstart etc we can help you troubleshoot. Have you logged into the console of the VM and check what it's doing and troubleshooted the network from the guest side?

Well, let me see if I'm even using the right tool, before we head down the rabbit hole.

My goal is to generate mostly identical images in various formats (ovf, ami, vhd, etc), customized using chef-solo. I'd like to start with a nicely pared down ubuntu image. My original plan was to simply do this in vagrant and then convert the resulting ovf to the varying platforms. Then I saw someone mention that packer might be a better tool.

Am I remotely on the right path?

SSH works when the ovf is booted by vagrant alone, so I assume that networking is fine. I cannot get vrdp to work at all to monitor the boot process with packer though.

Meanwhile, here's the template, I never make it to the provisioner:

I would say Packer is the right tool for that use case, but it's
important to understand that it doesn't take one source image and
convert it to multiple outputs. Instead it takes one source per
platform and do the same manipulations on each of the.

Why don't you just enable head? (headless: false)
And can you describe how you try to connect with VRDP?

OK, I think I finally get it. I'll need a base image on each platform and packer will just run chef-solo on each.

I haven't turned headless off because this is in a vm without X11. I'll probably build a new vm with it so I can turn it on.

Re: RDP, I've been trying to connect with the CoRD RDP client on MacOS using whatever port packer displays. The connection just times out. There are no firewall rules active on the vm running packer. Not entirely sure what's going on there.

When I get a non-headless version up, I'll let you know what I find.

Thanks.

So it just never boots I guess?

Here's the output of it just sitting there:

https://www.dropbox.com/s/d4iwviljt6div5d/packer.png?dl=0

The "Spurious NAK on isa0060/serio2" message appears when I press keys to release keyboard/mouse input from the VM, so that seems to be unhelpful and unrelated.

Not quite sure what to look at next...
