Error when running the start-qemu.sh in tdx host machine

Sound like the TDX SEAM module was not loaded successful, please refer the steps at https://github.com/intel/tdx-tools/blob/main/doc/verify_tdx_host.md

Which step should I follow in the document (https://github.com/intel/tdx-tools/tree/main/build/ubuntu-22.04) to set up the TDX SEAM module?

@hasinidilanka on Ubuntu, there is no dracut, so you can use initramfs-tool to do similiar thing for stiching the SEAM module into init ramfs.

Kernel loading SEAM module by linux kernel will be retired in future. Instead of loading from kernel, the seam module can loaded by IFWI BIOS or ESP partition as below picture.

Thank you for the pointers. For CentOS (Rhel-8) I suppose we can use the dracut. If I try to setup TDX on CentOS will I be able to use the SEAM module without any modifications?

yes, centOS stream and RHEL are almost compabile. :-)
