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.
