Packer Waiting for SSH - ssh

Question

I am new to Packer. I have researched this issue(above) in great detail. I am currently trying to create an UBuntu 32 bit VM. I am running Packer on a WIndows 10 OS. Once the installation is complete and the VM reboots and I am then prompted with GUI to login on my VM while packer still running my host Windows says it's waiting for SSH to become available. How may I best enable ssh for Packer to use to connect with my vm. Here is my json.template

P.S Yes I have looked at templates before coming to here and asking this question.

Answer 1

Actually, I got it. It was a combination of setting ssh_port to 22, setting ssh_address to my vm's address, setting ssh_skip_nat_mapping to true and than changing my nic card from internal network to hostonly and then configuring it.

Answer 2

You overwrite Packers setup of network and thus the host won't be able to reach the guest. To fix it remove the two following lines:
[ "modifyvm", "{{.Name}}", "--nic1", "intnet"],
[ "modifyvm", "{{.Name}}","--nic2", "null"],
