Paravirtualization pros and cons

Expert Bernard Golden takes a look at the strengths and weaknesses of paravirtualization in this expert response.

What are the strengths and weaknesses of paravirtualization compared to other virtualization?

Paravirtualization is very lightweight in comparison to the nearest competitor VMware ESX server, so its performance can be very good. In addition, it imposes its changes in a very few aspects of the kernel and allows many other aspects to continue working unmodified. In particular, it uses the native device drivers of its "host" OS (operating system), thereby offering more flexibility in terms of hardware support.

The most obvious drawback is that it requires a specialized kernel for guest OSes, if run on a non-virtualization-capable hardware platform. Getting that specialized kernel set up and configured properly can be a challenge, particularly for non-expert sysadmins.
