OpenVZ and LXC are both OS-level virtualization technologies that allow for the creation and operation of isolated Linux servers (containers) on a single physical server. Here are some potential advantages of OpenVZ over LXC:
1. Management Tools: OpenVZ has comprehensive management tools such as vzctl and vzlist that provide a greater degree of control on containers.
1. Stability and Maturity: OpenVZ has been around for longer than LXC, so it has a lot of stability and has matured over time.
1. Live Migration: OpenVZ supports live migration, which means that you can move a running container from one physical server to another without any downtime.
1. Better Resource Management: OpenVZ also provides better resource management capabilities. You can allocate a certain amount of CPU power, disk space, network bandwidth, and memory to each container and these allocations are enforced rigorously.
1. Templates: OpenVZ provides OS templates that users can use to easily create new containers in no time.
1. Backup and Restore: With OpenVZ, it is possible to make backups of containers and restore them when needed.
1. Community: OpenVZ has a strong and active user community, which often means quick bug fixes, regular updates, and reliable support.
However, the choice between OpenVZ and LXC may entirely depend on the particular needs of the user. It’s also worth noting that both technologies are being improved constantly.
