Guide to Open Source Virtualization Software
Open source virtualization software is an increasingly popular choice for businesses looking to save on costs and increase their productivity. It allows organizations to create virtualized machines or “containers” that can run isolated from the host system, allowing them to access computing resources more efficiently. This can be beneficial when it comes to testing new software or running multiple services on the same physical hardware without having any conflicts. There are a variety of open source virtualization solutions available today, including OpenVZ, KVM, Xen and VirtualBox.
OpenVZ is a container-based virtualization solution which allows users to easily create containers that act as completely separate virtual environments with their own disk space, memory, network interfaces and processes. The benefit of using OpenVZ is its ability to quickly provision new containers in minutes with minimal setup effort required by the user. It also offers support for a wide range of pre-configured Linux distributions making it ideal for web applications and databases.
KVM (Kernel-based Virtual Machine) is a type 1 hypervisor which provides high performance full-virtualization capabilities similar to those offered by commercial hypervisors such as VMware Workstation or Microsoft Hyper-V. KVM's main advantage over other types of open source virtualization solutions is its ability to manage large amounts of data in real time, providing users with improved performance when handling large workloads or mission critical operations.
Xen is another type 1 hypervisor that has been around since 2003 and runs on Linux systems only. Unlike OpenVZ and KVM, Xen creates fully isolated domains called "guests" rather than containers in order to provide better isolation between each guest operating system running inside the VM environment. Xen supports both Windows and Linux guests making this solution ideal for heterogeneous environments with different operating systems requirements such as multi-tier web architectures
Finally, there’s VirtualBox – an open source alternative geared more towards desktop/consumer usage than enterprise hosting needs. VirtualBox can be used not only for creating VMs but also cloning existing ones quickly while preserving hardware settings. As a result, it can be very useful when trying out new Operating Systems without needing additional hardware investments.
In conclusion, there are numerous benefits associated with open source virtualization solutions - primarily cost savings due to not needing proprietary licenses coupled with robust featuresets necessary even for complex enterprise workloads. Each solution mentioned above has some advantages over others depending on your specific use case so do research before committing into one direction.
