What's the best virtual machine program?

docker

vmware fusion

QEMU

VirtualBox. It just works. Not buggy like VMware.

LMAO

this

use kvm or boot into a xen kernel.

Menuet OS

Which is the best color?
Which is the best number?
Which is the best vehicle?

This is the problem with tech!
There is no best tool over all.
The question should always be
What are my needs, and which program/tool/system fulfills that need in the best way?
What is the budget?
what prior knowledge do I have?
How much is the support?
If its an open source project, is the community active, how fast is the development cycle?
Is this a hype driven project?

These kind off questions will give you an answer to which thing is the best solution at the specific time!

(Rant over!)
