ERROR: os_cap_init() error 3 #211

Closed igordptx closed 2 years ago

igordptx commented 2 years ago

I installed cat and enabled RDT in kernel. I get this error when trying to use pqos.

igor@acsl-serv02:~$ sudo pqos -I -D

Hey @igordptx, I am also facing the ERROR: os_cap_init() error 3 error when running pqos -s. I am guessing you were able to resolve the error as you closed this issue. Could you please let me know how you resolved the error? Thanks!
