Dinesh, your citation settings are broken. When sending plaintext, as 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.

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

Keys and certs generated by scripts/ are
