Canonical Shipping Updated Intel TDX Software For Ubuntu 24.04 LTS

([Ubuntu] 6 Hours Ago Intel TDX + Ubuntu)


Last year Canonical delivered an [1]Intel TDX "tech preview" for Ubuntu 23.10 to experiment with using Intel Trust Domain Extensions (TDX) found on the latest Xeon server processors. With Ubuntu 24.04 LTS they began shipping a formal TDX software stack and now have rolled out an update to that software stack as a stable release update.

The Intel TDX 2.1 software stack is now available on Ubuntu 24.04 LTS. This provides updated TDX kernel code atop Ubuntu 24.04's Linux 6.8 base, adds new features like kexec and kdump support for TDX-enabled hosts, updated to QEMU 8.2.2 and Libvirt 10.0, OVMF/EDK2 updates add Secure Boost support to Trust Domains, and other software updates from Intel.

A list of the Intel TDX 2.1 changes for Ubuntu 24.04 LTS can be found via [2]this GitHub page . There are known issues of nested virtualization not being supported, guest kexec not being supported, I/O device pass-through not being fully supported, and other limitations.

More details on the TDX 2.1 update for Ubuntu 24.04 LTS via the [3]Ubuntu Discourse . TDX is Intel's approach to isolation, confidentiality, and integrity at the VM level with modern Xeon processors.

Fortune's Exercising Truths:

1: Richard Simmons gets paid to exercise like a lunatic. You don't.
2. Aerobic exercises stimulate and speed up the heart. So do heart attacks.
3. Exercising around small children can scar them emotionally for life.
4. Sweating like a pig and gasping for breath is not refreshing.
5. No matter what anyone tells you, isometric exercises cannot be done
quietly at your desk at work. People will suspect manic tendencies as
you twitter around in your chair.
6. Next to burying bones, the thing a dog enjoys mosts is tripping joggers.
7. Locking four people in a tiny, cement-walled room so they can run around
for an hour smashing a little rubber ball -- and each other -- with a hard
racket should immediately be recognized for what it is: a form of insanity.
8. Fifty push-ups, followed by thirty sit-ups, followed by ten chin-ups,
followed by one throw-up.
9. Any activity that can't be done while smoking should be avoided.
