运行 dropbear 的 qemu arm64 镜像

我使用 dropbear 设置了 ARM64 qemu 映像。我正在尝试从主机 ssh 登录。我使用以下命令行来启动来宾。

#!/bin/bash

~/repos/qemu-2.6.0-rc3/aarch64-softmmu/qemu-system-aarch64 \
  -machine virt \
  -cpu cortex-a57 \
  -machine type=virt \
  -nographic -smp 1 \
  -m 2048 \
  -kernel ./arch/arm64/boot/Image \
  --append "console=ttyAMA0" \
  -net nic,model=virtio \
  -net user,hostfwd=tcp::10022-:22

在引导日志中我看到以下内容

drivers/rtc/hctosys.c: unable to open rtc device (rtc0)

Welcome to Buildroot
buildroot login: root

此外，我还可以ssh root@localhost对客人做一个。

但是，当我尝试从主机 ssh 登录时，我得到以下信息：-

$ ssh root@localhost -p10022 -vvv

此时我没有得到任何回应。为什么会出现这个问题呢？我的 ssh 配置只有以下几行，所以我想这不是问题。

ControlMaster auto
ControlPath /tmp/ssh_mux_%h_%p_%r

我已经在虚拟机上设置了 root 密码，并且希望能够使用 root 密码进​​行 ssh。

编辑

如果我等待足够长的时间，我会在详细输出中得到以下行。

ssh_exchange_identification: read: Connection reset by peer
