I had the same problem with a proxmox node that I'm using and the solution to this issue was solved by adding the serial port using the command qm set 102 --serial0 /dev/ttyS0. I thought that the same thing could be done here using xe or xl command; I just don't know how to achieve it in xcp-ng. The windows 11 vm shows a com1 port that has the same irq and i/o range numbers than the host; is this suppose to work?[image: 2025-02-04 13_13_16-Windows 11 Test Com 1 Properties.png] [image: 2025-02-04 13_15_05-ret-xcpng1 (ret-Resource Pool) node.png]
