[libvirt-users] Virtualization Management Platforms

[TomK]

Hey All,

Curious about the best, easy to use virtualization management platform 
for small labs of 30-40 physical servers.

Looking for something that's relatively simple to operate, install and 
lightweight but with enough maturity to provide monitoring as well as 
holistic views of the entire physical space etc.

Hearing of oVirt, Xen and Eucalyptus to name a few but wondering what 
other options do I have for a small physical space?
