I have a dual-processor machine with no keyboard/monitor on it that I would like
to use for Xen but I''m having problems getting the serial console to
work
properly.
I can see the system boot up into dom0 and I get the login prompt so it all
looks setup correctly, but it won''t take keyboard input - at least not
into the
login process on dom0. if I ssh into the box and try to read from the serial
port I still get nothing.
However, if I do ^a^a^a I can interact with the Xen code, so the serial port
itself is working, it just seems like it''s not getting passed down to
dom0.
I''ve had this from 2.0->2.0.3 and also with the latest unstable bk.
FWIW this is my grub entry:
title Xen (2.0/Linux 2.6.10)
root (hd0,0)
kernel /xen.gz com1=57600,8n1 dom0_mem=131072
module /vmlinuz-2.6.10-xen0 ro root=/dev/sda5 console=ttyS0

You''ll probably need to edit /etc/securetty too. Setup is per standard Linux console.

Setup is per standard Linux console.Yes, there''s a getty on there - I can see the login prompt. If I boot that partition using a "normal" Linux kernel it all works fine. I''ve had this machine on a serial console for ages. -- patrick ------------------------------------------------------- This SF.Net email is sponsored by: IntelliVIEW -- Interactive Reporting Tool for open source databases.

I am definitely running a getty in dom0; I get the actual login prompt. Is your machine doing some sort of BIOS serial console redirection? My Dell PE1650 has this turned on, but "off after boot" according to the settings. As no one else had reported this I''d put the problem down to Dell weirdness.

It''s not a DELL machine, it''s a Western Scientific, fairly old by today''s standards it''s a dual PIII/750 on (I think) a VIA chipset. -- patrick ------------------------------------------------------- This SF.Net email is sponsored by: IntelliVIEW -- Interactive Reporting Tool for open source databases.

I tried adding CONFIG_SERIO_SERPORT, which was the only serial- or console-related difference between my .config and the current defconfig that I could see, but there was no difference. I''m going to give the same 2.0.3 build a go on some different hardware when I get chance.
