[Xen-ia64-devel] xen hypervisor logs on hp zx6000

[Dietmar Hahn <dietmar.hahn@xxxxxxxxxxxxxxxxxxx>]

Hi all,

I tried xen on a hp zx6000 machine, but I don't get any xen-hypervisor messages
(starting with "(XEN) ") via the serial line. On boot the messages I see are:

ELILO boot: Uncompressing Linux... done
Loading file initrd-2.6.16-xen...done
Loading file vmlinuz-2.6.16-xen...done
Uncompressing... done

The next message appeared is:

Linux version 2.6.16-xen (hahn@sanpedro) (gcc version 3.3.3 (SuSE Linux)) #1 
SMP Wed Apr 26 14:14:10 CEST 2006

From here I see all messages from the dom0 kernel.
After login I checked the hypervisor messages with 'xm dmesg'.
I saw the following problematic line:
ERROR: I/O base address must be specified.
I looked through the source and found this message in 
ns16550_parse_port_config()
in xen/drivers/char/ns16550.c
For me it seems like a problem in the configuration of the serial interface in 
elilo.conf.
My configuration in elilo.conf is:
image=vmlinuz-2.6.16-xen
        label=xen 
        vmm=xen.gz 
        initrd=initrd-2.6.16-xen
        read-only 
        append="com1=115200,8n1 console=com1 sched=bvt -- nomca console=tty0 
console=ttyS0,115200 root=/dev/sda3"

Does anybody know the correct configuration or has anybody an another solution
for that problem?
Thanks!

Dietmar.
