Techworld.com: Is there a future for OpenVZ, which starts with an unavoidable comparison with Xen. I am not sure why they need to be compared at all -- paravirtualisation and container-based virtualisation are two completely different technology, and both have their pros and cons. On one hand, if you need a hypervisor and want to run full-blown OS, then you can't do that with OpenVZ. If you want burstable memory allocation, shared filesystem, and really utilise your hardware, then Xen is not the best choice. Simple.
