[Xen-users] XEN boot messages not visible on console
Hello, I''m not seeing any XEN boot messages at all. Xen boots OK, and afterwards I do get the DOM0 boot messages. I can also see the messages using xm dmesg. root@thunersee:~/work/xen/src/xen-4.0.0# xm dmesg (XEN) Bad console= option ''com3'' __ __ _ _ ___ ___ \ \/ /___ _ __ | || | / _ \ / _ \ \ // _ \ ''_ \ | || |_| | | | | | | / \ __/ | | | |__ _| |_| | |_| | /_/\_\___|_| |_| |_|(_)___(_)___/ (XEN) Xen version 4.0.0 (krist@RXXXX.net) (gcc version 4.4.3 (Ubuntu 4.4.3-4ubuntu5) ) Sat May 22 13:07:02 CEST 2010 (XEN) Latest ChangeSet: unavailable (XEN) Command line: dom0_mem=1024M console=com3 com3=115200,8n1 As you see xen complains about hte console. However, according to the info I found here: http://wiki.xensource.com/xenwiki/XenHypervisorBootOptions Or should I interpret "Xen supports up to two 16550-compatible serial ports" as meaning "XEN only supports com1 and com2"? Com3 is the port that I can see using the SOL funtion of the IPMI build in to the server. Krist -- krist.vanbesien@gmail.com krist@vanbesien.org Bremgarten b.

I think it is that com1 defaults to the standard irq/address but you can
redefine it
menuentry "Xen 4.0 / Ubuntu 10.4 kernel 2.6.32.10-xen7 pvops IOMMU
SERIAL" {
insmod ext2
set root=''(hd0,2)''

You can specify the correct IOport/IRQ parameters for them to get it working.
