Waiting to reconnect during connection between windbg and Vm

 

Recently, during driver debugging and learning, follow the instructions in many documents to modify the boot. ini file.

 

[Boot loader]

Timeout = 30

Default = multi (0) disk (0) RDISK (0) Partition (1)/Windows

[Operating systems]

Multi (0) disk (0) RDISK (0) Partition (1)/Windows = "Microsoft
Windows XP Professional "/noexecute = optin/fastdetect

Multi (0) disk (0) RDISK (0) Partition (1)/Windows = "Microsoft
Windows XP Professional "/noexecute = optin/fastdetect/debug/debugport = COM1/baudrate = 115200

In this way, when windbg is used to connect to the VM, it may be found that windbg stops at waiting
Reconnect..., cannot connect to the virtual machine.

After analysis, it is found that the virtual serial port created by the VM is sometimes the com2 port and the device name is serial port2. On the hardware manager of the system on the VM, only the com2 port is found, but no COM1 port is found. In this case, the boot. ini settings are incorrect. Change the boot. ini file
