    I get how to remote kernel debug a VM but I want to setup a physical machine to do remote kernel debugging but can’t figure out how that is meant to be done with VisualKernel or is it not really supported yet. I couldn’t find any tutorials or help that shows how to do this other than via a physical serial port. I would be interested in mapping a serial port to a tcp/ip port as well as how to configure gdbserver for kernel debugging. Thanks.

    Hi,

    How do you want to map a physical serial port to a tcp/ip port? Do you mean using a separate Linux machine connected to your target machine via a serial port and the development machine via ethernet?

    OK, so I’m moving forward trying to remote debug on two separate physical systems with a USB to serial cable and get the target machine to stop responding so I know some communication is occurring
    My target is CentOS 6.5 64-bit. Here are my questions:

    1. Should I be using a null modem rather than a straight serial cable.
    2. my target serial device gets instantiated as /dev/ttyUSB0 should I enter ttyUSB0 in the COM port on Linux machine text box?
    3. Should I be able to communicate between the two machines using a terminal emulator on both ends?

    Any help would be appreciated. Let me know what logs I can post here to help. Thanks.

    Hi,

    We’ve just added support for debugging over network to VisualKernel 1.1. Have a look at the following tutorial: http://visualkernel.com/tutorials/network/
