事象内容
vagrant 1.8をインストールしテスト環境を作成したところ、
以下のエラーが出て一向にVMの起動が進まない。
$ vagrant -v
Vagrant 1.8.5
$ vagrant up

(以下略)
対応方法
まずはVM側のフォルダの許可権を変更。
$ chmod 0700 /home/vagrant/.ssh/
$ chmod 0600 /home/vagrant/.ssh/authorized_keys
$ chown -R vagrant /home/vagrant/.ssh/
この状態でVMを起動。
$ vagrant up

default: /vagrant => /Users/yuta/vagrant/centos7
・・・解決したようだ。
2016/09/02追記
authorized_keysファイルはの許可権は600にする必要がある。(参考に追加)
また仮想マシンをsuspend -> resumeした時にまたまた認証のエラーが出ていたので公開鍵を置き換えないように記述を追加する。
Vagrantfile
## 公開鍵を置き換えないようにする。
config.ssh.insert_key = false
なお、/var/log/secureに認証エラーのログも出力されている。
Aug 30 16:05:21 localhost sshd[3371]: Connection closed by 192. 168.0.1 [preauth]
Aug 30 16:05:21 localhost sshd[3373]: Authentication refused: bad ownership or modes for file /home/vagrant/.ssh/authorized_keys
