Thanks for taking the time to provide feedback

This is not supposed to happen. What host platform are you using?

We've seen this issue and will handle the VM management better.

There should be a service running to synchronise time : /usr/bin/VBoxService
Running this command as root in the SDK will tell you the status
  systemctl status vboxservice.service

Auto completion should work - the header files in the SDK are shared with the
host using the 'targets' shared folder. We're improving testing in this area too.
