>From the error message, it seems that your SSH key has not been properly
set up, and hence Vagrant is refusing to set up the VM.

You can either change the ownership and permissions on this file

/home/sdn/hdd/tutorials/vm/.vagrant/machines/p4-tutorial/virtualbox/private_key

so they are owned by the user running Vagrant and have the right
permissions for SSH (see for example
https://superuser.com/questions/215504/permissions-on-private-key-in-ssh-folder
)

Alternatively, if you generate your own SSH key, you shouldn't have any
trouble. To go this route, try the ssh-keygen command-line utility (and see
tutorials like this:
https://www.digitalocean.com/community/tutorials/how-to-set-up-ssh-keys--2)
