To build the virtual machine:
- Install [Vagrant](https://vagrantup.com) and [VirtualBox](https://virtualbox.org)
- Clone the repository
- Before proceeding, ensure that your system has at least 25 Gbytes of free disk space, otherwise the installation can fail in unpredictable ways.
- Before proceeding, ensure that your system has at least 12 Gbytes of free disk space, otherwise the installation can fail in unpredictable ways.
- `cd vm-ubuntu-20.04`
- `vagrant up` - This step typically takes over 1 hour to complete, and requires a reliable Internet connection throughout.
- `vagrant up` - The time for this step to complete depends upon your computer and Internet access speeds, but for example with a 2015 MacBook pro and 50 Mbps download speed, it took a little less than 20 minutes. It requires a reliable Internet connection throughout the entire process.
- When the machine reboots, you should have a graphical desktop machine with the required software pre-installed. There are two user accounts on the VM, `vagrant` (password `vagrant`) and `p4` (password `p4`). The account `p4` is the one you are expected to use.
*Note*: Before running the `vagrant up` command, make sure you have enabled virtualization in your environment; otherwise you may get a "VT-x is disabled in the BIOS for both all CPU modes" error. Check [this](https://stackoverflow.com/questions/33304393/vt-x-is-disabled-in-the-bios-for-both-all-cpu-modes-verr-vmx-msr-all-vmx-disabl) for enabling it in virtualbox and/or BIOS for different system configurations.
