Per Wiki:-

2) If your computer running Xen doesn't have a real physical
serial port you can add a PCI add-on serial card with a DB9
serial connector. This is a good option for many computers.

seems to be the cheapest solution. No matter for AMD or Intel.
Thanks Pasi once again.



I'll check if there are any open slots and see if I can find an
addon serial card.

Well, I could not find even one local electronics/computer store that carried a serial port card. Had to order it online which will take
some time.  Maybe I can capture a video of the boot sequence.


I tried to capture some video of the pv_ops dom0 boot
sequence problem on Gigabyte AMD hardware and I posted it on youtube.
Here's the link:  http://www.youtube.com/watch?v=OcuwH7S-qZA
It was a little fuzzy before the upload but got real fuzzy afterwards.
But I think you can make out the critical parts.

I uploaded another take and it came out a little better:

You seem to be missing most of the dom0 linux kernel boot messages..

Please paste your grub.conf.

Pasi, my grub.conf is attached.

Ok, fix it to be like this:

module /vmlinuz- root=/dev/mapper/vg--grp--01--23--02--2-LogVol00 dummy=dummy ro earlyprintk=xen console=hvc0 console=ttyS0 console=ttyUSB0,115200n8 text

aka remove "quiet" and add "earlyprintk=xen console=hvc0"

-- Pasi

Pasi, this gave some more output. Sorry the video is fuzzy but this happens by youtube postprocessing. Here is new link: http://www.youtube.com/watch?v=jePyapeHpSI

If you have somewhere I can ftp original video file, it is clearer. File is about 90 MB.


Original video is posted here: http://greno-misc.googlecode.com/files/MOV03932.MPG
