将以下行添加到您的Vagrantfile：
Vagrant.configure(2) do |config|
# ...
config.ssh.private_key_path = "vagrant_rsa"
config.vm.provision "shell", path: "openssh.ps1"
config.vm.provision "file", source: "./vagrant_rsa.pub", destination: "~/.ssh/authorized_keys"
end
其中vagrant_rsa和vagrant_rsa.pub是位于当前vagrant项目文件夹中的私钥和公钥（例如由生成ssh-keygen -t rsa -C "your@email.here"），并且openssh.ps1是：
$is_64bit = [IntPtr]::size -eq 8

这是joefitzgerald / packer-windows openssh设置脚本的简化版本。
现在您可以vagrant ssh进入Windows框。
对于那些使用vagrant-libvirt的用户，您可能希望将某些端口（如RDP）从主机转发到来宾。vagrant-libvirt使用ssh进行端口转发，因此您需要按照上述说明在Windows上设置ssh，然后才能转发以下端口：
config.vm.network :forwarded_port, host: 3389, guest: 3389, id: "rdp", gateway_ports: true, host_ip: '*'
