File server timeout for Rocky kickstart

[Mitch Murphy]

Overview of the Issue

I am attempting to use Packer to build some Rocky Linux 8.9 ISOs for Vagrant, however I get a timeout when trying to access the file from the built in file server

Reproduction Steps

You can find my code (quite simple) here

Packer version

From packer version: 1.10.2

Simplified Packer Template

You can find the HCL config here

Operating system and Environment details

Linux pop-os 6.6.10-76060610-generic x86_64

Log Fragments and crash.log files

After the machine is initially bootstrapped I get the following error (on the VM)

curl (7) Failed to connect to 10.0.2.2 port 8222: Connection times out
[ <ts>] dracut-initqueue[920]: Warning: anaconda: failed to fetch kickstart from http://10.0.2.2:8222/ks.cfg
...

During which time Packer prints these errors (over and over):

I fixed it, needed to add this configuration to my source

  vboxmanage           = [
    ["modifyvm", "{{ .Name }}", "--memory", "${var.memsize}"],
    ["modifyvm", "{{ .Name }}", "--cpus", "${var.numvcpus}"],
    ["modifyvm", "{{ .Name }}", "--nat-localhostreachable1", "on"]
  ]
