Vagrant up and SSH auth method

Let’s take a sneak peek to Vagrant first. Vagrant is a tool to build and manage VMs. It works as a command-line utility.

Vagrant configures and provision VMs as described in the Vagrantfile. The command to create and configure this VM as per the Vagrantfile is vagrant up.

In config.ssh we can configure the way we can access the machine. And hence while running vagrant up we can also SSH into the machine.

Usually, we activate the Hardware acceleration in the BIOS environment.

We also check the Network settings and choose the Adapter 1. Here, we make sure to select the option Cable Connected.

If the Vagrantfile is corrupted, then our Support Engineers would reinstall and setup Vagrant for the customers.
