Hi all, I'm setting up SOL (Serial-over-LAN) but can't see OS boot message -- GRUB and login prompt are OK. Could anyone please tell me how to use SOL? http://wiki.xensource.com/xenwiki/XenSerialConsole says to set xencons=ttySX, but all messages after GRUB are disappeared when setting xencons=ttyS2 because dmsg and setserial can't find out ttyS*. [root@charlie ~]# dmesg | grep ttyS Bootdata ok (command line is ro root=/dev/vg_dom0/lv_root xencons=ttyS2 console=ttyS2) Kernel command line: ro root=/dev/vg_dom0/lv_root xencons=ttyS2 console=ttyS2 Xen virtual console successfully installed as ttyS2 [root@charlie ~]# setserial -g /dev/ttyS* /dev/ttyS0: No such device or address /dev/ttyS1: No such device or address Cannot get serial info: Invalid argument /dev/ttyS3: No such device or address When setting xencons=off, I can see GRUB and login prompt via SOL but (XEN) message is not shown on all devices (via SOL and console monitor) and OS boot message is shown on console monitor only.
