[pve-devel] [PATCH manager v3 2/2] Add support for TDX attestation

Tue Oct 28 13:54:27 CET 2025


Add configuration options for the quote-generation-socket used to
communicate with the Quote Generation Service. This enables attestation
support for TDX using vsock or unix sockets.

More information can be found at:
https://www.qemu.org/docs/master/interop/qemu-storage-daemon-qmp-ref.html#object-QSD-qom.TdxGuestProperties

This only includes support for vsock and unix sockets. The SocketAddress
object in QEMU also supports inet and fd, which are not commonly used in
TDX.
