Description
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:

Have you installed the unrestricted policy into your Jenkins JVM?
By default it limits the maximum RSA key size to something like 2048 or 4096

added a comment - Thanks stepenconnolly my searching before posting was not turning up anything useful. That was exactly the issue and works now as expected. I will close this out.

Just tested on 1.597 as well and the same issue and error message is present
