Bare Metal Hypervisor – Proxmox VE

Website: http://www.proxmox.com/products/proxmox-ve

Open-Source alternative to VMWare ESXi.

Plus:

• Free
• Easy install
• Just works!

Minus

• No built-in support for USB
• Not that good at taking changes, machines have a tendency to get stuck  when initial boot fails, even when changing the CDs in the virtual drive. And shutting them down doesn’t always work to fix the issue, have had to reboot the hypervisor.
• Drivers for para-virtio network card should be included
• Is SCP really the only protocol to connect to the box?
