Spcie客户端显示调试信息的方法

源码编译并安装spice客户端，系统中会有一个简单用来测试的客户端程序spicy，我们只需要添加spice-debug命令参数，就可以看到客户端spicy的所有调试信息了，并且我们也可以在代码中使用封装好的调试信息输出接口，添加调试信息。

[root@localhost ~]# spicy --spice-debug

(spicy:98799): GSpice-DEBUG: spice-session.c:160 New session (compiled from package spice-gtk 0.26)

(spicy:98799): GSpice-DEBUG: spice-session.c:164 Supported channels: main, display, inputs, cursor, playback, record, smartcard, usbredir

(spicy:98799): GSpice-DEBUG: usb-device-manager.c:874 device added 0x2a76c90

(spicy:98799): GSpice-DEBUG: spicy.c:1733 connection_new (1)

(spicy:98799): GLib-GObject-WARNING **: g_object_get_valist: object class 'SpiceSession' has no property named 'unix-path'

(spicy:98799): GSpice-DEBUG: spicy-connect.c:177 spicy_connect_dialog: #0 [host]: "localhost"

(spicy:98799): GSpice-DEBUG: spicy-connect.c:177 spicy_connect_dialog: #1 [port]: "(null)"

(spicy:98799): GSpice-DEBUG: spicy-connect.c:177 spicy_connect_dialog: #2 [tls-port]: "(null)"

如果想要把调试信息全部输出到/root/spicedbg文件中，那么需要如下执行：

[root@localhost ~]# spicy --spice-debug 1>/root/spicedbg 2>&1
