AppleVirtUI errors in guestagent.log

Docker Desktop for Mac
1

I keep getting these reported every second in /var/log/guestagent.log

Any ideas? It appears to be docker related.

Note though - this is edge + Mojave +.1 beta

Still very unclear about this service and I do not recommend running these commands until it is

launchctl list | grep --only-matching --with-filename --line-number --before-context=2 AppleQEMUGuestAgent

launchctl stop com.apple.AppleQEMUGuestAgent

launchctl remove com.apple.AppleQEMUGuestAgent

I see no mention of this service except for on RedHat. From what I’ve learned, it’s a service that allows guest connections to perform actions on a host.
Personally, I’m not interested in such service so I removed it

Saw the damn thing spin up again.

Got this when digging:
$ sudo launchctl unload /System/Library/LaunchDaemons/com.apple.AppleQEMUGuestAgent.plist
/System/Library/LaunchDaemons/com.apple.AppleQEMUGuestAgent.plist: Operation not permitted while System Integrity Protection is engaged
