We are using OpenVZ for our testing and development purposes. We have several websites that run on OpenVZ containers. It is also used bt our development teams for their proof-of-concept and testing projects.
- It is container-based virtualization
- It is not resource-heavy
- It is better then KVM
- Since it is a container-based solution, you can't run any other OS, except for Linux
- It is not so popular as Docker, but it's not that bad

- It's free, so you can try it and figure out if it suited for your needs
- Docker
Kubernetes and Docker are de-facto standards today, but I think that OpenVZ and Proxmox are better solutions
