Released as Open Source Software (OSS) in June 2014, OpenXT is a collection of hardened Linux VMs configured to provide a user facing Xen platform for client devices. This default configuration was mostly static, applying some disaggregation techniques to segregate system components based on a general threat analysis. The goals embodied in this code base up to its release produced a one-size-fits-most configuration with extensibility in specific areas to encapsulate 3rd party value-add. With a community now forming around OpenXT we must come to terms with the limitations of the this approach. In this talk Philip will define what OpenXT is and in this definition, show that OpenXT can meet the varied needs of the security and virtualization community through the construction of a toolkit for the configurable disaggregation of a Xen platform.
