Linux.com has a nice article on Xen, Linux, TPM, and TXT. It also mentions the OpenXT toolkit.

OpenXT is an open-source development toolkit for hardware-assisted security research and appliance integration. Released as Open-Source Software (OSS) in June 2014, OpenXT stands on the shoulders of Xen Project and OpenEmbedded. It is derived from XenClient XT, which was first released in May 2011. It includes hardened Xen VMs that can be configured as a user-facing virtualization appliance, for client devices with Linux and/or Windows guests. It has been used to develop managed software appliances to isolate demanding graphics workloads, untrusted workloads and multiple networks on a single laptop or desktop. OpenXT is optimized for x86 devices with Intel VT-d, TXT (Trusted Execution Technology) and a TPM. OpenXT is being developed to meet the varied needs of the security and virtualization communities, as a toolkit for the configurable disaggregation of operating systems and user workflows. Client appliances developed on OpenXT can contain a mixture of open-source and proprietary software, supporting a range of business models.[…]
