I just started playing around with VMware ESXi 5 which appears to be free! Yey! 🙂
You can download it at the VMware website, http://www.vmware.com/products/vsphere-hypervisor/overview.html. Don’t forget to apply for the license which is free, otherwise you get a 60-day trial.
The reason I choose VMware ESXi was because I’m pretty familiar with VMware. I’ve had their workstation as long as I can remember. I actually had a license for both Linux and windows at one point. And umm… because that’s really the only one I could use on my server, hardware restraints. 🙂
There are a few other free virtualization software packages.
- Citrix XenServer
- Proxmox (open source) – does KVM and OpenVZ
- VMware ESXi
