Timed out while waiting for the machine to boot. This means that Vagrant was unable to communicate with the guest machine within the configured ("config.vm.boot_timeout" value) time period. If you look above, you should be able to see the error(s) that Vagrant had when attempting to connect to the machine. These errors are usually good hints as to what may be wrong. If you're using a custom box, make sure that networking is properly working and you're able to connect to the machine. It is a common problem that networking isn't setup properly in these boxes. Verify that authentication configurations are also setup properly, as well. If the box appears to be booting properly, you may want to increase the timeout ("config.vm.boot_timeout") value.
対処法
最初は認証用の鍵ファイルに問題があると思って調べていたのだけど、以下のページによるとどうやらVagrantのバグっぽい。
Vagrant 1.8.5でLinux boxをvagrant upするとエラーが出る件について – 素敵なおひげですね

[インストール先]\embedded\gems\gems\vagrant-1.8.5\plugins\guests\linux\cap\public_key.rbの56行目に
chmod 0600 ~/.ssh/authorized_keys
を追加してからVMを再作成してやれば直ります。
説明に従って修正したら問題解決。感謝。
