[pve-devel] [PATCH edk2-firmware/manager/qemu-server v3 0/9] Add support for Intel TDX

[Anton Iacobaeus <anton.iacobaeus@canarybit.eu>]

This patches series adds support for launching Intel TDX confidential
VMs via QEMU. Basic attestation support is also added.

Intel TDX requires QEMU >= v10.1 and kernel >= 6.16. A TDX compatible
CPU is also required, with TDX enabled in the BIOS. Attestation also
requires a running Quote Generation Service (QGS) on the host (or
dedicated VM) connected to a Provisioning Certificate Caching Service
(PCCS), more information can be found at:
https://cc-enabling.trustedservices.intel.com/intel-tdx-enabling-guide/02/infrastructure_setup/

Only a subset of the possible socket types are implemented with this
patch. Ideally the SocketAddress object as defined in QEMU would be
fully implemented, but for the sake of TDX this is not neccessary. More
information at:
https://www.qemu.org/docs/master/interop/qemu-storage-daemon-qmp-ref.html#object-QSD-sockets.SocketAddress

The TDX object can also be extended with additional configuration
options, but these are not neccessary for regular usage of TDX. More
information available at:
https://www.qemu.org/docs/master/interop/qemu-storage-daemon-qmp-ref.html#object-QSD-qom.TdxGuestProperties

Future work can build upon this patch to improve these shortcomings.

Thanks to Fiona for the review.

Changes since v2: https://lists.proxmox.com/pipermail/pve-devel/2025-October/075766.html
* Fixed nits and formatting
* Added reasoning for firmware Config-B 
* Added reasoning for kernel_irqchip=split
* Added support for configuration of the quote-generation-socket for attestation.
