Hi I work with the developers on upstream TDX support. Now that the TDX support in kvm-coco-queue is getting more mature, we thought it's the time to do regression test on normal VM and it might be useful to start sharing the results of our testing on the list. This is in addition to the normal suite of automated tests that run in our CI. Except the issue[0] which was already reported on upstream KVM, no other new issues were hit, especially no known regression bugs in the "MMU part 1", "VM/vCPU creation" or "MMU part 2" patches.
