Xdebug trough a nat VM SERVER

Question

我有一个虚拟机在我的系统上运行，它承载了一个apache web服务器和一个php应用程序，我试图通过xdebug进行调试，guest vm使用RedHat virtmanager配置，是一个在qcow2中转换的Hyper-V机器，接口的网络类型是NAT(默认):guest的当前地址是:

192.168.122.78

我尝试了xdebug的各种配置，当前的配置是:

zend_extension=xdebug.so
xdebug.mode = debug
xdebug.client_host = 192.168.122.1
xdebug.client_port = 9003
xdebug.log=/var/www/clients/client1/web4/web/xdebug.log
xdebug.discover_client_host = false

我得到了xdebug。client_host客户端内部运行的IP地址:

$ echo $SSH_CLIENT | awk '{ print $1}'
192.168.122.1

我在Vscode中配置了php-xdebug扩展:

{
"version": "0.2.0",
"configurations": [
{
"name": "Listen for Xdebug",
"type": "php",
"request": "launch",
"port": 9003,
"hostname": "192.168.122.78", --->ip adress of guest machine
"pathMappings": {
"/var/www/clients/client1/web4/web": "${workspaceRoot}"   
}

},
{
"name": "Launch currently open script",
"type": "php",
"request": "launch",
"program": "${file}",
"cwd": "${fileDirname}",
"port": 0,
"runtimeArgs": [
"-dxdebug.start_with_request=yes"
],
"env": {
"XDEBUG_MODE": "debug,develop",
"XDEBUG_CONFIG": "client_port=${port}"
}
},
]
}

但是我得到这个错误

Error: listen EADDRNOTAVAIL: address not available 192.168.122.78:9003
at Server.setupListenHandle [as _listen2] (net.js:1301:21)

code: 'EADDRNOTAVAIL',
errno: -99,
syscall: 'listen',
address: '192.168.122.78',
port: 9003
}

据我所知，xdebug调用连接到客户端(我的主机)，客户端侦听此端口:如果我尝试telnet并检查端口是否通过客户机的ip地址连接，我将收到一个连接拒绝错误:

$ telnet 192.168.122.78 9003                                                                                                                                                                                  
Trying 192.168.122.78...
telnet: Unable to connect to remote host: Connessione rifiutata

我在服务器上没有任何iptables规则，因为我删除了它们并接受所有传入和传出的连接:

$ iptables -L -v -n
Chain INPUT (policy ACCEPT 329 packets, 28028 bytes)
pkts bytes target     prot opt in     out     source               destination         
Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
pkts bytes target     prot opt in     out     source               destination         
Chain OUTPUT (policy ACCEPT 261 packets, 31104 bytes)
pkts bytes target     prot opt in     out     source               destination    

这是服务器的xdebug日志:

[1366] Log opened at 2021-10-27 13:32:21.938749
[1366] [Step Debug] INFO: Connecting to configured address/port: 192.168.122.1:9003.

显然启用xdebug.discover_client_host = false不能改变这种情况。

你知道是什么导致了这个问题吗?任何帮助都是感激的。致以最亲切的问候。

hostname": "192.168.122.78"，——>主机ip地址

我想那是你的问题。那里的hostname应该为空，或是Xdebug要将连接到的IP地址。，在你的例子中是192.168.122.1。
