When it comes to the main context of OpenVZ vs KVM, it is necessary to get a clear understanding of both these technologies individually. Both KVM and OpenVZ are well-known virtualization technologies used on an extensive scale in the VPS and SMB hosting arenas. Both these systems come with their exclusive benefits and features that make them perfect for specific applications.
Here, we will be getting an overview of KVM vs OpenVZ while even comparing the two technologies so that it helps in making the right decision when it comes to choosing between the two.
OpenVZ offers virtualization for just the Linux platform. It allows Linux servers to be sliced into multiple isolated virtual units. The technology uses one Linux kernel, and this is the reason why the virtual units on this platform can operate Linux. On the other hand, KVM allows users to turn their Linux servers into hypervisors. The server is divided into several virtual units with their very own CPUs, graphics adapters, network cards, disks and memory. The differences between OpenVZ vs KVM come down to exclusive or individual contexts and situations.
When trying to choose between KVM vs OpenVZ, there is no better way of coming up with the right decision than simply evaluating your requirements. It all depends on what you will be using the server for. Remember, with KVM, you will have to reboot your server for new system resources while with OpenVZ, you need to upgrade the plan you are using.
