Dinesh, your citation settings are broken. When sending plaintext, as it
is common on public lists, you need to set the mark "> " at the
beginning of all cited line.
Yes, just now I have changed settings and made it plaintext while replying, earlier it was HTML. I hope it will fix this issue.
Thanks for pointing it.

Do you want to mention qemu-system-x86_64 --version should be 5.2.0 or
higher as default Debian buster has older version of qemu and this step
fails with older version.
Also these steps can't be executed remotely as it launches UI window for
QEMU, so it should be done locally.
Feel free to send a patch (or MR if that is easier) that adjust things,
Dinesh.
   Sure, I will do that.

Where are you taking care of my below point? I don't see it yet

    Keys and certs generated by scripts/generate_secure_boot_keys.sh are
    not available to build command, so I have to move them in
    recipes-devtools/ebg-secure-boot-secrets/files/ folder to make it work
Quirin?
