Do All Intel® Xeon® 6 Processors Support TDX Connect?

Unable to determine if all Intel® Xeon® 6 Processors support Intel® Trust Domain Extensions Connect (Intel® TDX Connect) technology.

Intel® Trust Domain Extensions (Intel® TDX) is a technology designed to enhance the security of virtual machine environments. It introduces a new type of virtual machine guest called a Trust Domain (TD), which operates in a CPU mode that protects the confidentiality of its memory contents and CPU state from other software, including the hosting Virtual Machine Monitor (VMM), unless explicitly shared by the TD itself.

Key Features of Intel® TDX

• Trust Domain Live Migration: Enables the movement of a trust domain-enabled virtual machine between systems.
• Trust Domain Preservation: Allows updates to Intel® TDX without shutting down the trust domain or restarting the system.
• Remote Attestation: Verifies that workloads in a trust domain are authentic and untampered.
• Logical Memory Integrity Support: Detects software-based attacks and supports ECC devices.
• Cryptographic Memory Integrity: Provides stronger security properties for ECC devices, with a trade-off against RAS (Reliability, Availability, and Serviceability).

Supported Processors
Intel® TDX is supported on processors that include Intel's Virtual Machine Extensions (VMX) and Intel® Total Memory Encryption – Multi-Key (Intel® TME-MK). Specific processor families include:

• Intel® Xeon® Scalable Processors (for example, Sapphire Rapids, Emerald Rapids).
• Intel® Xeon® 6900/6700/6500-Series Processors with E-Cores.
