VirtualBox network is a bit quirky. By default packer sets up nat for ssh.
So by default it ssh to 127.0.0.1:<random port> where this is NAT'ed to the
guest IP port 22. If you want to suppress this see
https://www.packer.io/docs/builders/virtualbox-iso.html#ssh_skip_nat_mapping
But if you are just learning Packer I would recommend that you instead
remove ssh_address and let packer handle that.
