vagrant ssh get错误：ssh\u交换\u标识：读取：对等方重置连接

我正在安装buildroot。但是当我从buildroot文档中下载手册时，出现了错误

这是我的过程

curl -O https://buildroot.org/downloads/Vagrantfile; vagrant up

结果如下

==> default: Attempting graceful shutdown of VM...
    default: Guest communication could not be established! This is usually because
    default: SSH is not running, the authentication information was changed,
    default: or some other networking issue. Vagrant will force halt, if
    default: capable.
==> default: Forcing shutdown of VM...
==> default: Checking if box 'ubuntu/bionic64' is up to date...
==> default: Clearing any previously set forwarded ports...
==> default: Clearing any previously set network interfaces...
==> default: Preparing network interfaces based on configuration...
    default: Adapter 1: nat
==> default: Forwarding ports...
    default: 22 (guest) => 2222 (host) (adapter 1)
==> default: Running 'pre-boot' VM customizations...
==> default: Booting VM...
==> default: Waiting for machine to boot. This may take a few minutes...
    default: SSH address: 127.0.0.1:2222
    default: SSH username: vagrant
    default: SSH auth method: private key

然后我尝试连接ssh

vagrant ssh

但也有北向的表现。就这样

lt@ubuntu:~/qemu/buildroot$ vagrant ssh

所以我尝试使用ssh命令

lt@ubuntu:~/qemu/buildroot$ vagrant ssh-config

不过，也有北上的表现

你能给我一个建议吗？谢谢。

尝试执行以下命令：

vaggrant-halt

vagrant up

vagrant ssh

这应该可以解决这个问题。如果仍然存在，请检查bios设置以确保已启用虚拟化。如果您的电脑在windows上，请确保hyper-v已禁用。

这是一个重复的问题，并已回答多次

你可以在这里参考我的答案

Host default
  HostName 127.0.0.1
  User vagrant
  Port 2222
  UserKnownHostsFile /dev/null
  StrictHostKeyChecking no
  PasswordAuthentication no
  IdentityFile /home/lt/.vagrant.d/insecure_private_key
  IdentitiesOnly yes
  LogLevel FATAL

ssh vagrant@127.0.0.1 -p 2222 i /home/lt/.vagrant.d/insecure_private_key
