Server Virtualization Software
Server virtualization software lets a physical server run virtual machines; deployment options and guest operating system support help determine which tool fits your setup. Compare those details alongside hypervisor type, live migration and central management.
The signal score is out of 10. The API, open-source and free-tier marks give quick signals to compare, while the board also shows free plans, starting prices and supported platforms when that information is available.

How to choose
Where does the software need to run?
Start with deployment and platform support. The board lists options such as self-hosted, Linux and web, so check for a match with how you manage servers and the systems your team already uses.
Platform labels describe where a product is available; they do not by themselves tell you which guest operating systems it supports. Check guest OS support separately.
Which hypervisor type fits my setup?
Compare hypervisor type with your intended server environment. The board includes this detail, but the right fit depends on your setup and the guests you need to run.
Check guest OS support before committing, since compatibility is a separate comparison point.
How many virtual machines can run on a host?
Use the VMs-per-host detail to compare stated capacity. Consider it alongside your expected workload and the server resources you have available; the board does not prescribe a capacity for your setup.
Do I need live migration or central management?
If you need to move running virtual machines between hosts, compare live migration support. If you manage a server group from one place, compare central management.
These are separate capabilities, so check both rather than treating one as a substitute for the other.
How can I compare free and paid options?
Check the free-plan mark and the paid-from price, if shown. A free trial is different from a free plan, and pricing on request means you will need to ask the provider for details.
For example, ACRN Hypervisor and KVM are listed with free plans, while Citrix XenServer is listed with a 90-day trial and pricing on request.
Questions
What is server virtualization software?
It runs virtual machines on a physical server, letting you compare server environments through details such as hypervisor type, guest OS support and VMs per host.
What should I compare when choosing server virtualization software?
Compare deployment, hypervisor type, VMs per host, live migration, central management and guest OS support. Check platform availability and pricing too.
Which platforms do server virtualization tools support?
Listed platform types include self-hosted, Linux, web, API, Windows and macOS. Check a product's platform details to confirm it fits your setup.
Is server virtualization software free?
Free plans and paid products are both represented. Check whether a product has a free plan, a trial or a paid price; some providers give pricing on request.
What does live migration mean in server virtualization?
Live migration is the capability to move a running virtual machine between hosts. Compare the listed support if moving VMs is part of your needs.
