From Dave Scott on xen mailing lists:

We are pleased to announce the open-sourcing of the ‘xapi’ toolstack — as used in the Citrix XenServer product line. The xapi toolstack is licensed under the LGPL v2.1 with a special static linking exception. The toolstack:

manages the lifecycle of VMs (installing from templates, running, suspending, migrating, creating snapshots and checkpoints and import/export)
binds hosts together into single “Resource Pools”
interfaces with heterogeneous storage services through a plugin mechanism
manages host and VM networking, including bonding and VLANs
records multi-resolution persistent performance statistics
generates alerts when performance thresholds are crossed or multipathed storage degrades
authenticates users through either PAM or Active Directory
supports Role-based access control
actively manages VM memory allocations through ballooning
supports host software upgrade without VM downtime (“rolling-upgrade”)
plans for host failure, performs admission control and automatic VM restart
exposes the XenAPI over HTTP/S
provides secure tunnelling for VM console traffic
includes a Java applet for viewing consoles and a Javascript XenAPI client demo
supports a simple plugin mechanism for extension
when used with the open-source CIM provider [http://community.citrix.com/display/xs/Kensho] provides a full DMTF CIM API with OVF support

The released code is the current development version (“trunk”) and is under active development. The repositories are here:

http://xenbits.xen.org/xapi/xen-dist-ocaml.hg — scripts and Makefiles to build some external library dependencies
http://xenbits.xen.org/xapi/xen-api-libs.hg — internal libraries (e.g. for talking to xenstore) http://xenbits.xen.org/xapi/xen-api.hg — the toolstack itself

The easiest way to build the code is in a specially-prepared VM, instructions are here:

From now on, all development will take place on the xen-api@lists.xensource.com
mailing list. In the future we plan to move relevant content such as documentation, designs, roadmaps etc. onto the main xen.org wiki.

Comments, criticism and contributions are welcome!
