Before you choose
Compare free access and paid terms
Some entries provide no-cost plans, whereas others follow paid pricing. Citrix XenServer gives pricing details by request and includes a 90-day trial.
Check whether a free plan fits your deployment, then review paid terms when you need commercial support or broader capacity.
Match the deployment model
Deployment options include self-hosted software, Linux, web interfaces, application programming interfaces, Windows and macOS. HPE VM Essentials lists Linux and web support, while Huawei FusionCompute offers self-hosted and web deployment.
Choose a tool that fits where administrators and workloads run.
Check the virtualization design
Compare hypervisor type and the stated virtual machines per host. These details indicate how the platform creates virtual machines and how much guest capacity it targets.
For workloads that must shift between hosts, live-migration support may be relevant. Central management matters when administrators control hosts from one place.
Verify guest operating-system support
Support for guest operating systems is one of the fields compared here. Before selecting a platform, verify that your intended systems are named in its published support information.
Review code and licence terms
Some entries make their source code available. If modifying or reviewing code is important, inspect the licence and project terms before deployment.
Questions
How does server virtualization software work?
It lets one physical server run separate virtual machines, with tools for deploying and managing those virtual environments.
Can server virtualization software be free?
Yes. No-cost plans appear among entries such as ACRN Hypervisor, Firecracker, Harvester, IPFW and KVM.
Do any products offer free trials?
Yes. Citrix XenServer includes a 90-day trial, although trial conditions vary among products.
Which deployment platforms are represented?
The list includes self-hosted, Linux, web, API, Windows and macOS options. Product support varies, so check the maker's details.
