Hi，
I have update the code into 20.05-rc2. However， the l3fwd-power
startup fail.

This was not happening in your previous logs, have you got the 'msr'
kernel module loaded?

I did not see any GUEST_CHANNEL notifications in the previous logs you
provided, has your setup changed in any way?
By the way, I can run the command you provided above (without the
whitelist) without any errors on my system, and a single CTRL-C exits
gracefully. I am not running in a VM.
Rgds,
Dave.
