我已在 Slackware 15.0 主机上成功运行旧的 UNIX SVR4 来宾。

机器启动并识别旧的 WD 卡，我可以从内部 ping 到内部（原文如此！），但不能从主机到来宾，反之亦然。
这是网络情况，没有界面出现

我尝试过绑定..

答案1
实际上，pcap 在 Linux 主机上似乎是一场灾难，稳定版本不起作用，git 版本首先从客户机 ping 会崩溃
86Box[23929]: segfault at 3c8 ip 0000000000655468 sp 00007f18317fd940 error 4 in 86Box[426000+40e000]
Slirp 网络似乎有效。因此，我认为 ATM 的 pcap 网络在 Linux 主机上存在漏洞。
ps=老的SVr4系统被qemu完美模拟
qemu-system-i386 -m 16 -hda unix.img -fda boot.img
但qemu不支持wd8003 isa卡。
编辑：找到了解决方法/解决方案。使用 vde 代替 pcap 或 slirp。
我们需要一个点击界面，我个人使用这个脚本
#!/bin/sh
# Exit at first error
set -e
# Run this as root
if [ $UID != "0" ]
then
echo "Run this script as root"
exit 1
fi
# Increment tap device number
TAP=`ip link show type tun|grep tap|awk '{print $2}'|cut -d : -f 1|cut -c 4|tail -1`
let "TAP=TAP+1"
TAPDEV=tap${TAP}
# Other vars
USER=yourname
BRIDGE=br0
# Create tap for user
ip tuntap add dev $TAPDEV mode tap user $USER
ip link set $TAPDEV up promisc on
ip link set $TAPDEV master $BRIDGE
echo "I have created $TAPDEV for user $USER, using bridge $BRIDGE"
echo "To remove it use command ip link delete $TAPDEV as root"
然后创建交换机作为ROOT（普通用户可以创建交换机..但是当您启动86box机器时它不会连接到交换机！）
sudo vde_switch --mode 666 --numports 8 --tap tap1 --mgmt /tmp/vde.manag --mgmtmode 666 -s /tmp/vde.switch --daemon
然后我们启动86Box
控制vde交换机后，必须报告两个端口（tap1和86box程序）
vdeterm /tmp/vde.manag
VDE switch V.2.3.2

Success
Tap1 必须配置网桥的 ip 类别，例如，如果 br0 具有 192.168.0.1/24 ip tap1 必须具有 192.168.0.*/24，对于虚拟机也是如此（例如：
br0 192.168.0.1
tap1 192.168.0.2
vm 192.168.0.3
终于出结果了！

我第一次在我的电脑上看到旧的 svr4 Unix 上的 telnet，而不使用 slirp 和其他缓慢的解决方案！
