LDoms 1.0.3

Logical Domains (LDoms) 1.0.3 is now available. This release is mainly intended to enable many new features included in Solaris 10 5/08 (aka update 5). Jason did an excellent job with details & logistics in this blog entry, so there's no need in my repeating that info here.

One thing I do want to mention in terms of LDom Manager functionality is that with this release, the XML format produced by the

ldm ls-constraints -x
command has changed. While the LDom Manager will continue to accept our previous, so-called v2 XML format, as of 1.0.3, it also accepts & produces the new v3 format. This format is designed to closely align with the schema defined as part of the draft Open Virtual Machine Format (OVF) specification.

This is just the tip of the iceberg. Coming in LDoms 1.1 (currently targeted for release in Q4CY08) will be a complete XML based control interface for monitoring & managing Logical Domains, based on this same v3 schema. In addition, it will utilize the XMPP transport, providing secure, standards-based XML messaging between client application & the LDom Manager.

This combination of a standards-based schema over a standard XML transport provides a rich control interface for creating management applications. More details about this new management interface, including detailed specifications, will be forthcoming.
