'ser_baud=xxx' option gone away

'ser_baud=xxx' option gone away

[Keir Fraser]

The Xen boot option 'ser_baud=<baud>' has been removed from the
unstable tree. If you were still using this obsolete option then the
effect is that you will get no serial output when you boot Xen, which
may lead you to believe that there is a more serious problem.

To fix this you must move to the new boot option:
 'com1=<baud>,8n1'

more bootupproblems with xen

[Rune Johan Andresen]

[-- Attachment #1: Type: text/plain, Size: 767 bytes --]

Hi, thanks for answers. Grub can now find the files, but there are even 
a worse nut to solve now:

When booting I get this messages:

Warning: unable to open an initial console.
Kernel panic: no init found. Try passing init= option to kernel

This is a common failure message in bootup, but I am not sure what I do 
wrong now.

df -k gives:

/dev/hda2    38076936   4064044 etc..
/dev/hda1    124427 	......			/boot
none		..... 		.......		/dev/shm


grub conf :

title Xen

	root(hd0,0)
	kernel /xen.gz dom0_mem=131072 watchdog noreboot com1=115200 noht
	module	/xenolinux.gz root=/dev/hda1 ro console=tty0


Any ideas? I have trried to search for this problem but have not got 
any useful. I am useing the last
binary stable xen version.

Thank you!  :-)

noht

Are you using xen-1.2? Then try: ser_baud=115200 instead of the com
option.

The com1 option was introduced in unstable tree some time ago.

Lot's of things have changed since the 1.2 release so suggestions made
on the mailing-list will not apply to all versions of Xen.

We try to keep the documentation in README and README.CD up-to-date, at
least after major changes have stabilized.

Hi Rune,

I've only run 1.0 but I use grub and may have some ideas.  The kernel 
and module instructions may require a full path.  Also, df -k shows 
/dev/hda1 as /boot.  You need to specify where / lives.  I'm guessing 
it's /dev/hda2.  If so, try this in your grub.conf file.

   root(hd0,0)
   kernel /boot/xen.gz dom0_mem=131072 watchdog noreboot com1=115200 noht
   module /boot/xenolinux.gz root=/dev/hda2 ro console=tty0

Hope that solves the problem.
