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.

した挙句にエラーを吐き、vagrant sshでパスワードを求められる
原因
vagrant1.7以降の仕様です
vagrant upすると、対象のゲストOSに対して新たな鍵のペアを生成して配置するため、
環境によってはデフォルトのinsecure_private_keyとの合わずにエラーが発生する
config.ssh.insert_key - If true, Vagrant will automatically insert a keypair to use for SSH, replacing Vagrant's default insecure key inside the machine if detected. By default, this is true.
This only has an effect if you do not already use private keys for authentication or if you are relying on the default insecure key. If you do not have to care about security in your project and want to keep using the default insecure key, set this to false.
ssh.insert_key がtrueの場合、
vagrantはvagrant内のデフォルトの安全でないキーが検出されると、SSHで使用する鍵ペアを置き換える未使用の秘密鍵の場合、デフォルトの安全でないキーを使用している場合にのみ影響がある
セキュリティを気にする必要があり、デフォルト安全でないキーを使用したい場合、これをfalseに設定してください
直し方
Vagrantfileに下記追加
config.ssh.insert_key = false
追加前
vagrant ssh-config ⏎ Host default HostName 127.0.0.1 User vagrant Port 2222 UserKnownHostsFile /dev/null StrictHostKeyChecking no PasswordAuthentication no IdentityFile /Users/heleeen/work/infra/deploy_test/.vagrant/machines/default/virtualbox/private_key IdentitiesOnly yes LogLevel FATAL
追加後
$ vagrant ssh-config Host default HostName 127.0.0.1 User vagrant Port 2222 UserKnownHostsFile /dev/null StrictHostKeyChecking no PasswordAuthentication no IdentityFile /Users/heleeen/.vagrant.d/insecure_private_key # ここが変わる IdentitiesOnly yes LogLevel FATAL
