    Setting up a VM with VirtualBox fails with ssh issues. I have confirmed it is not an issue with my key by logging into the Jenkins install and using the same user it does was able to ssh to the VirtualBox machine without any issue. I tried an ssh key with and without a password both fail in jenkins the same way. Both ways work if manually done as the jenkins user to login through ssh to the running vm. The key size and type rsa 16384 with no rounds on password. error: [VirtualBox] Launching node testbox [VirtualBox] Powering up VirtualBoxMachine{host=VirtualBoxHost{url='http://vboxmain:18083', username=''},name='testbox'}...
