Today's challenge was to run some archaic Windows software within a kernel virtual machine (KVM) with the end goal of programming radio equipment through a RS232 serial connection.
I own a programming cable that has a male USB-A connector on one end and a male RJ-45 connector that is plugged into the serial port of a Motorola CDM1550-LS+. This connector presents a Prolific PL2303 USB to serial chipset on the USB, which is handily recognized by Linux. I was then able to get this to show up as a normal serial port under KVM, but, unfortunately, virt-manager 3.2.0 doesn't provide this capability in the UI when adding serial hardware.
Therefore, XML editing must be enabled before making the appropriate addition to the hardware tree.
<serial type="dev">
<source path="/dev/ttyUSB0"/>
<target type="isa-serial" port="1">
<model name="isa-serial"/>
</target>
<alias name="serial1"/>
</serial>

| Thanks, virt-manager, but where's "Pass-through serial device (dev)" |

I am trying to pass this same serial device through to my Linux guest. How (and where) does this device appear in the guest os?
In my case, the device ended up as "COM2."
If you have other serial devices I think you can change the number of the "port" option above, such as:
target type="isa-serial" port="1"
hello hi this solved my problem thank you thank you!
How about sharing how to enable XML editing...
