Once you get familiar with it, it is a pretty capable and easy to use platform. It allows you to quickly get an overview of how the system in whole is behaving, and to jump into a container causing issues for other containers on the host, and resolve the issue.

The provisioning of the containers is pretty fast, allowing quick delivery time for new clients.

It is a free solution (which allows to ignore some of the potential issues which come with using it).

When setup with a proper backup solution, it becomes a pretty sturdy solution for what it does. Review collected by and hosted on G2.com.

Aforementioned "issues for other containers on the host" are the biggest issue - one misbehaving container on the host can cause headache for all other sharing clients, which in worst case scenario makes them regret moving from shared hosting to higher price solution, to again be greeted with the same issues.

High number of active containers on the host can lead to disk IO issues, slowing down all containers.

Occasionally network issues arose (interfaces missing, IPs being lost, connectivity problems). Review collected by and hosted on G2.com.

openvz uses less resources as it does not do a complete hardware virtualization like VMware. It acts like a container like LXC. Low overhead. Review collected by and hosted on G2.com.

Configuration of hardware resources are cumbersome, specially the container memory params. I had to calculate and understand all those parameters.

More user friendly template based configuration would have helped.

I used to do it few years ago and every time I had to read and understand "Container Memory Parameters". Review collected by and hosted on G2.com.
