Hi, guys, I have a problem here. Now i am using a motherboard without serial port, and i want to debug xen to get some system log, so i use one usb2UART line to redirect serial port to USB. After that, i configure system according to this link: http://wiki.xensource.com/xenwiki/XenSerialConsole, and change the ttyS0 to ttyUSB0. But i can not get any log, so is there anyone can help me?

(but you can use usb-serial on another computer to log the serial console output). Xen needs to have access to a real serial port (either physical or virtual SOL (Serial Over LAN)). So I recommend you to buy a PCI serial card.. -- Pasi _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
