KVM vs Hyper-v 2012 Performances

Hi,
right now am using Openvz (under Proxmox) for Linux VMs and VMware ESXi for Windows VM
and I want to move from VMware to other platform
options:
1. KVM
2. MS Hyper-v 2012

Considering I've already work with Proxmox for Openvz and the Differences in performance between KVM and Hyper-v 2012 (if any - I don't know)
What would you recommend me to work?
KVM or Hyper-v 2012?

Best Regards,
Star Network.

Hi

The worst is if you buy onde Datacenter 2012 License, you can have unlimited VM's...
This is kill Proxmox, KVM or any other hypervisor....
 
How does that "kill" Proxmox?
You can have unlimited VM's with Proxmox without paying anything :)
