Vagrant is an open-source software product for building and maintaining portable virtual software development environments. It focuses on automation and eliminating the need for manual configuration of development environments. With Vagrant, developers can quickly set up and tear down development environments, making it easier to work on multiple projects and quickly switch between them. It also helps with configuration management and version control, allowing developers to keep their development environment up to date and in sync with the rest of their team. Vagrant also supports multiple virtualization and cloud providers, such as VirtualBox, VMware, AWS, and DigitalOcean, making it easy to quickly spin up a development environment in any environment.
Mesos is designed to run production clusters, while Vagrant is designed exclusively for local development.
virt-manager is not a tool to automate VM creation.
