the "vagrant" user will not have permissions to do anything in /root because it will have 0700 perms. Therefore anything in /root or in any subdirectory under /root etc will not be accessible by any use other than root. Prefix it with sudo and it should work.
This is the correct setup and I strongly recommend that you leave /root's perms as 0700. Don't chmod 0755 to make that command work or anything.
