Quick Guide to Setting Up an Ubuntu Virtual Machine with Vagrant

Before starting, ensure that Intel Virtualization Technology is enabled in the BIOS/UEFI settings.

Download and install VirtualBox , a popular virtual machine manager.

Download and install Vagrant , which simplifies creation and management of virtual machines.

Verify the installation by running the vagrant command in a terminal.

Add an Ubuntu box from a domestic mirror (Tsinghua University) using one of the following commands, depending on the desired Ubuntu version:

# Ubuntu 18.04 LTS
vagrant box add https://mirrors.tuna.tsinghua.edu.cn/ubuntu-cloud-images/bionic/current/bionic-server-cloudimg-amd64-vagrant.box --name ubuntu18

# Ubuntu 16.04 LTS
vagrant box add https://mirrors.tuna.tsinghua.edu.cn/ubuntu-cloud-images/xenial/current/xenial-server-cloudimg-amd64-vagrant.box --name ubuntu16

# Ubuntu 14.04
vagrant box add https://mirrors.tuna.tsinghua.edu.cn/ubuntu-cloud-images/vagrant/trusty/current/trusty-server-cloudimg-amd64-vagrant-disk1.box --name ubuntu14

Initialize a Vagrant configuration file:

vagrant init

Edit the generated Vagrantfile (located at C:\Users\Administrator\Vagrantfile ) and replace the default box line:

config.vm.box = "base"   # change to
config.vm.box = "ubuntu18"

Start the virtual machine:

vagrant up

Once the VM is up, connect to it via SSH:

vagrant ssh
