I'm trying to get the following working: Serial port (/dev/ttyS0) passthrough to a PV or HVM domain, together with xenfb and usb passthrough. passthrough of the serial port works fine in a PV without xenfb (and so without qemu) by using the following lines in the config: irq = [4] ioports = ["3f8-3ff"] by using vfb = [ 'vnc=1,vnclisten=0.0.0.0,vncunused=1' ] it will use qemu, so the lines ... Jun 23, 2020 · How can I setup the RV50 serial port (or USB as serial) to communicate with an RS485 device. I have an RS485 to USB and an RS485 to RS232 converter, and can use either, but I am not sure how to configure the serial (or USB) port to stream commands between my PC and the serial device through the RV50. i connect to the RV50 remotely with a static ip address, and would like to set the serial port ...

A virtual machine can use up to 32 serial ports.

Qemu/KVM can output its virtual serial port data to a real serial port, a file, a unix domain socket or a TCP socket on the host. The first thought was to see if a pty would do as the serial port, but an experiment with socat indicated that this can't work. Normally, QEMU uses SDL to display the VGA output. With this option, you can totally disable graphical output so that QEMU is a simple command line application. The emulated serial port is redirected on the console. Therefore, you can still use QEMU to debug a Linux kernel with a serial console. 所以只要輸入到uart就可以對應到console
