Question

如何将串口console重定向

Answer 1

测试环境:
Host OS: SUSE Pro 9.3
vmware: 4.5.2 for linux (any-any-update89)
Virtual OS: SLES9 两台 (SLES9serv1, SLES9serv2)

关键词:
Linux, console, serial, vmware, console loglevel

Linux 的系统的 console 可以重定向到串口，系统的 console 消息可以通过终端软件记录下来，对分析系统的故障
很有帮助。 由于没有串口线，所以只好借助 vmware 来测试这个功能了。

vmware 4.5.2 支持将串口创建为命名管道(在 linux 下实际是socket)
具体的做法如 vmware 文档 file:///usr/lib/vmware/help-manual/devices_serial_ws.htm 所介绍的方法

In the server virtual machine
Open the virtual machine settings editor (VM > Settings).
Click Add to start the Add Hardware Wizard.
Select Serial Port, then click Next.
Select Output to named pipe, then click Next.
In the Path field, enter /tmp/ or another Unix socket name of your choice.
Select This end is the server.
Select The other end is a virtual machine.
By default, the device status setting is Connect at power on. You may deselect this setting if you wish.

In the client virtual machine
Open the virtual machine settings editor (VM > Settings).
Click Add to start the Add Hardware Wizard.
Select Serial Port, then click Next.
Select Output to named pipe, then click Next.
In the Path field, enter /tmp/ or another Unix socket name of your choice. The pipe name must be the same on both server and client.
Select This end is the client.
Select The other end is a virtual machine.
By default, the device status setting is Connect at power on. You may deselect this setting if you wish.
