Hyper-V redirects serial output to a named pipe, no file option. Send output to a physical serial port on the host system. Select where the virtual serial port sends output. Click Finish to add the virtual serial port to the virtual machine. In VMWare ESX I could do something similar, where the serial port can be redirected to a file giving me the same effect. In the Add Hardware wizard, select Serial Port. Kernel /vmlinuz-2.6.18-274.el5 ro root=/dev/VolGroup00/LogVol00 rhgb quiet console=tty0 console=ttyS0,38400 hda=noprobe hdb=noprobe
In the case of the VMware Workstation serial port named pipe. The normal way to do this on a physical machine is to add the console parameters to the kernel in grub like what's below, connect it to another machine via a serial port and null modem cable and use minicom, hyperterminal or TeraTerm with matching settings, which would enable viewing the console startup messages on the machine and debug output if the kernel crashes (and log them to a file in the case of Tera Term). When I start the VBox Windows7 and launch Putty, then type in COM1, but there is no.
I would like to redirect the serial port output on RedHat 5.7 to some recordable or reviewable medium.
