[bouke-nederstigt]

It has to do with ansible picking the wrong key to provision the mesos-master instance.
If you add

ANSIBLE_RAW_SSH_ARGS = []

  cluster.each_with_index do |(hostname, info), index|
    ANSIBLE_RAW_SSH_ARGS << "-o IdentityFile=.vagrant/machines/#{hostname}/virtualbox/private_key"
  end

just above cluster.each_with_index do |(hostname, info), index| in the Vagrantfile

and ansible.raw_ssh_args = ANSIBLE_RAW_SSH_ARGS to the provision loop, everything should be fixed.

[rasputnik]

Might be due to Vagrants ssh key recycling (default in newer versions).
Setting

config.ssh.insert_key = false

in the Vagrantfile should fix it.
