[libvirt-users] Deploying OVF on Different virtual platforms

Hi All, I am new to Virtualization and Libvirt. Pardon if any information is missing.! I am using VMware PowerCLI And Python to automate tasks for managing my Virtual Infrastructure. I have recently come across Libvirt. and have certain questions. Q1. Can Libvirt be used to deploy OVFs on ESX servers.? Q2. If I wrote a script using Libvirt's Python binding ( A simple one, Say turn on/off/suspend VM) , will that script work on different virtualisation platforms.( HyperV, XEN, VMware-ESX ) ? Q3. Is there a suitable reference for Libvirt's Python APIs ? Thanks, Nikunj Bangalore-India
