Intel Trust Domain Extensions (TDX) is a VM-based trusted execution environment which attempts to isolate confidential guest VMs from the host, similar to AMD SEV-SNP. Like AMD SEV-SNP it requires guest modifications (also referred to as "enlightenments") to operate in the TEE. Initial support for running Linux in a TDX guest environment was merged [in 5.19][1]. The guest driver used for generating attestation reports was merged [in 6.2][2]. Enable both of these options on supported kernel versions. This matches other distros such as [Arch Linux][3], [Debian][4], [Fedora][5], [openSUSE][6], and [Ubuntu][7].
