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?
Yes. But what I don't understand is that the dpdk version I use is
different, and the kernel module is the same. the 20.05-rc0 is ok when
startup and the 20.05-rc2 is not. I don't notice the msr module.

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.
I don't running vm. I want to test the 20.05-rc2 according to your
advice. the kernel is the same.
Rgds,
Dave.
