[ERROR] failed to read msr 0xc0010131 when running verdictd

Hello, I successfully installed Verdictd on my laptop, but when I try to run it I receive this weird error, which I cannot understand:

╰─➤  sudo verdictd                                                                                                                          130 ↵

I did some searches and I found out that msr 0xc0010131 is related to the fact that my CPU doesn't support AMD SEV (I don't get any output when typing either dmesg|grep SME or dmesg|grep SEV.
Does it mean that I cannot use Verdictd on my machine?

Another thing: before installing Verdictd I could successfully test rats-TLS with sample client and server but after Verdict installation I cannot run rats-TLS client and server anymore, moreover I receive the same error [ERROR] failed to read msr 0xc0010131, which was not present before. What does it mean?

The error message "failed to read msr" should be not printed by default. The AMD SEV platform detection should go background. I will submit a patch to mute the noise. Right now you can simply ignore it.

Do you try to specify another listening port such as "verdictd --listen 127.0.0.1:3333" to ensure sample rats-TLS server doesn't listen the same port against Verdictd?
