let's try this with a shorter subject, which was originally this,
which probably tripped the list-admin-approval triggers....
Xen 3.2 Debian 2.6.18 on Dual Xeon with Remote Serial access -
grub.conf config advice needed
the subject says it all - anyone who knows the answer can stop reading
and hit "send" with a few lines of grub.conf - however, for those
people who are bored, intrigued, or prefer a little less obtuse
requests for help, here's a little bit more waffly version:
i have a debian/testing system which is, rather unusually, on a dual-xeon
system where the _only_ access i have, to this leased server, is via a serial
console. yes - the BIOS boots over the serial console not the VGA screen.
(for those people who know blackcatnetworks, it's one of their leased servers)
i could really do with some advice on how to configure grub correctly. what i
have so far shows absolutely nothing on the serial console beyond loading
the two modules and going "boot". then it goes silent, i can't see the startup
log messages, and i have to pray that i got everything right and sit
uncomfortably
for a couple of minutes, pinging the remote ip address.
here's what update-grub managed to generate:
title Xen 3.2-1-i386 / Debian GNU/Linux, kernel
2.6.18-5-xen-vserver-686
root (hd0,0)
kernel /boot/xen-3.2-1-i386.gz
module /boot/vmlinuz-2.6.18-5-xen-vserver-686 root=/dev/md0
console=ttyS0,9600 ro console=tty0
module /boot/initrd.img-2.6.18-5-xen-vserver-686
savedefault
boot
yes, i know - the two console= lines are because (if you know debian you'll
appreciate this) the #kopt= line is this:
# kopt=root=/dev/md0 console=ttyS0,9600 ro
sooo, update-grub goes "oh look, xen! let's append console=tty0 on the
end of the kernel options"!
duh.
anyway, _after_ manually editing the grub config every time at startup,
to remove one of the extra console= lines, i get a chance to bite my
fingernails until ping happily shows up - over the public internet.
i am not a happy bunny: i seriously need console access and can't make
head nor tail of the obtuse descriptions of xencons=tty etc. that i'm reading
about on various HOWTOs and FAQs.
some rather direct and simple instructions, from people who clearly know
what they're doing much better than i could achieve by randomly rebooting
a server which is going live in a couple of days _and_ hosts some existing
live web sites, would be greatly appreciated.
