Could you publish your ubuntu-server-18.ova somewhere so we can try reproduce it?

What steps did you do to troubleshoot the network/connectivity? Try running with --on-error=ask and the VM will keep running after the time out so you have time to troubleshoot.

i reproduced the same issue on a mac host machine. therefore i don't think it as a circleci issue. here is the image:

https://drive.google.com/file/d/1AZvpqyrY5fojfUtl6qShB5aMYgU4_ny5

and template:

{

  "builders": [

    {

      "type": "virtualbox-ovf",

      "source_path": "https://drive.google.com/file/d/1AZvpqyrY5fojfUtl6qShB5aMYgU4_ny5",

      "ssh_username": "packer",

      "ssh_password": "packer",

      "ssh_timeout": "15m",

      "shutdown_command": "echo 'packer' | sudo -S shutdown -P now"

    }

  ]

}

If you start that build, wait for the console, login with packer/packer and run "ifconfig" you will see there is only a loopback interface.

Thanks Rickard. I went ahead configuring the network on ubuntu boot with the script posted below. On a mac host with packer 1.3.1 this works well. However when running in a circleci pipeline, packer build hangs on ssh:

==> virtualbox-ovf: Waiting for SSH to become available...
==> virtualbox-ovf: Timeout waiting for SSH.

I guess there is no dhcp in circleci so tried installing a dhcp server but that did not solve the problem as well. 

```

#!/bin/bash

if [ -f /etc/network/interfaces ]; then

  mv /etc/network/interfaces /etc/network/interfaces.orig

fi

echo "# generated on startup"  >> /etc/network/interfaces

echo  >> /etc/network/interfaces

for networkfile in /sys/class/net/*; do

    [ -e "$networkfile" ] || continue

    [ "$networkfile" != "/sys/class/net/lo" ] || continue

    networkname=$(basename $networkfile)

    echo auto $networkname >> /etc/network/interfaces

    echo iface $networkname inet dhcp >> /etc/network/interfaces

    echo  >> /etc/network/interfaces

done

cat /etc/network/interfaces

ifreload -a

```

VirtualBox box have it's own dhcp server so you don't need to install that. More likely circleci have some restrictions on networking that interfere with this.
