Most Xen installations do not do so. upstream says: "TMEM has been described by its maintainers as a technology preview, and is therefore not supported by them for use in production systems. Pending a full security audit of the code, the Xen.org security team recommends that Xen users do not enable TMEM." We will not be fixing this in Ubuntu.
