From the ConVirt documentation:
"ConVirt is a powerful virtualization management platform for administering and automating your Xen infrastructure. Use ConVirt if you need centralized management; if you need high availability, backup & restore, and workload management; if you need self-service for your customers; or if you want to manage your virtualization infrastructure from a "single pane of glass"."
- ConVirt 2.5 is Open Source. It can be installed locally or as a pre-built VM image from the Convirture website.
- ConVirt currently integrates with xm/xend. Support for xl/libxenlight and/or libvirt is on their roadmap.
- Integration logic is a little stale, apparently with the last explicitly supported version of Xen Project software being 3.2
