Xen was one of the first reliable hypervisors to be released. It is & was so powerful, that any time someone said "virtual server", you would think Xen, and it is currently the number one & most used virtualization platform in the cloud, which says a lot. Since Xen is separate from the OS & goes even further by separating out each component, it provides exceptional security, performance, and full OS neutrality, letting you run any OS you want in a virtual environment. Xen has many cutting edge features, and is always adding more, while making sure it is one of the most stable platforms available. Review collected by and hosted on G2.com.
Xen does not offer a wide variety of easy to use management tools, and you should expect the same level of management tools as most other open-source software. The command line also requires quite a bit of training, though command syntax and how-to's are all over the internet. Review collected by and hosted on G2.com.
