I am using Hyper-V Manager on my Windows 8.1 device to host a virtual machine. As it turns out, there is no way to enable your COM ports through the user interface, instead you must use Windows PowerShell (as described here and shown below).I have followed the directions provided in the link above, and I can see the VM COM ports (1 & 2) listed in the device manager of the VM. The problem that I am facing is that when I create the virtual COM port, the port cannot be opened. Within the Card Access software, only COM1 and 2 are options even though all of the ports are listed in the device manager. I’ve read several posts regarding the need to specify named pipes from Hyper-V COM ports.
From Hyper Serial Port:
HyperSerialPort is a Serial Terminal Emulator that works with any Serial Port including USB to Serial Virtual COM Ports. The HSP has several built in test tools that assist in the development of embedded electronics such as: Python Scripting Evaluator, Auto-Send Characters, External Trigger etc. It is built on the .NET Framework 4.0 from Microsoft and designed for Windows 7 and 8 Systems. It is a 32 bit application. How is HyperSerialPort used HyperSerialPort runs on any Windows Vista, 7, and 8 PC. It uses the Virtual COM Port driver of the USB to Serial Converter (or the physical COM Port driver of the PC). Tools included in Hyper Serial Port: Python Scripting Evaluator: The Python Scripting Evaluator allows developers to run Python scripts within the HyperSerialPort environment. This will allow users to develop real time feedback loops to mimic processor to device communications. The user could write a script to emulate an I2C device and use an embedded processor to communicate with the I2C device and debug communication errors. Caution must be used when using this mode. HyperSerialPort does not put any restrictions on using Python scripts. The user could scripts which could damage the OS. Care must used when writing Python scripts in this mode. Auto-Send Character: The Auto-Send Character Function allows the user to send a repeating character or string at a timed sequence over the serial port. This function utilizes the high resolution property of Windows 7 OS. This will allow the timer to reach up to 700 microsecond time between characters sent. Some caution must be exercised with timed sequences in the Windows 7 OS. This operating system is a non-deterministic operating system. This means, it cannot guarantee the timer will expire at 700 microseconds for each sequence. External Trigger: The External Trigger function will pause the incoming characters on a serial port until a selected character or string appears on the selected trigger serial stream. This allows the user to capture an event that may be difficult to see when a serial stream is continuously updating the serial terminal window. Multi-Terminal Window: The Multi-Terminal Window allows multiple terminal windows to be opened each attached to it's own serial port. The multi-terminal window allows the user to view several serial port communications simultaneously.

I have a Hyper-V guest running CentOS 7. When the guest panics and prints a kernel Oops message, is it possible to capture the text written to the console? Note that the message is not written to dmesg, and thus, cannot be retrieved on the next reboot. https://excellentbrown535.weebly.com/aashiqui-mp3-songs-free-download.html.

To add a serial port to a VM, create one (or more) named pipes in PowerShell. Note that PowerShell must be 'run as administrator' for this to work. The example here uses a VM named
dv0 .
Hyper-v Windows 10
In the Linux VM, add the console setting via grubby for
COM1 (a.k.a. ttyS0 ): Download 7z for windows 10.
PuTTY can capture the output from the named pipe. In the session options, use Serial for the destination, ctuffli
.pipedv0-com1 for the Serial line, and 115200 for the Speed to match the Linux console settings. Because the named pipes are created as Administrator, PuTTY must also be 'run as administrator'.
