Hi As TDX support has been merged into linux-next, we thought it's the time to do a new round of regression testing on normal VM and it might be useful to share the results on the list. This time, we tested 2 configurations to increase the test coverage: 1) Disable TDX in BIOS and kernel Kconfig 2) Enable TDX in BIOS and initialize TDX successfully on host. The test results of these 2 configurations are the same. During the testing, we encountered 2 PMU bugs[0][1], which are not related to TDX patches. No other new issues were hit.
