Can you attach the full serial console output (that includes Xen bootup, kernel
logs, and then lastly the error you are seeing).

You can buy two DB9-RJ-45 adapters (like this one: http://www.pccables.com/01910.htm)
and use a RJ-45 cable between. This way you can even have a 100m null modem cable between.

Sorry, I cannot do it right now. I need move boxes back, i.e. very close to each other ( 2.5 m). NULL modem cable is very short. I will do it as soon as i can  ( 1-2 days). 
I apologize for inconvenience and understand that it's very important for you.

So what is hanging? Grub2? - No kernel rc8
************************************************
I don't have dmesg for Ubuntu 9.04 Server.

What is that from? The title says Ubuntu 9.04? Or is this from another Linux distro?

But you do have the console message which has 'udevadm' on it. That implies
that Dom0 did boot up.

Re: Attempt to load 2.6.31-rc8 under Xen 3.4.1 on top of Ubuntu 9.04 Server

[Boris Derzhavets]

[-- Attachment #1.1: Type: text/plain, Size: 1495 bytes --]

Problem with serial console output.

Grub Entry on testing box:-

title Xen 3.5 Serial / Ubuntu 9.04 Jaunty (kernel 2.6.31-rc8)
     kernel /xen-3.5.gz dom0_mem=1024M loglvl=all guest_loglvl=all com1=19200,8n1 console=com1
     module /vmlinuz-2.6.31-rc8 ro root=/dev/sdc2 console=hvc0  earlyprintk=xen
     module /initrd-2.6.31-rc8.img

On connected box in text mode:-

# cat /dev/ttyS0 | tee log

I am getting unreadable output

Source box - Ubuntu 9.04 Server installed in location RU,Moscow
Target box -  Fedora 11 installed in location RU,Moscow

I suspect it to be a reason of the issue. When locations were NY,US
i never got such kind of problems.

Boris.

That might be due to baudrate not being set right. Can you use minicom instead (and obviously
set the right baudrate).

So the serial port settings do not match in the servers..

Change the xen-3.5-gz line in grub.conf to have "com1=9600,8n1", maybe
that's a better default..

Or then don't use "cat /dev/ttyS0", but use "minicom" instead.. and
configure the speed etc there (I think it's O or P to go to configuration).

You need to have same speed/settings on both servers for the serial
console logging to work OK.

Earlier Boris was telling that 2.6.31-rc8 dom0 kernel works when he has
dom0_mem=4096M but it fails (tracebacks) when dom0_mem=4097M.

Boris: can you make two logs; one with dom0_mem=4096M and another with
4097M. Don't change anything else between the log captures, only that
dom0_mem parameter.

Udevadm patches are both in Xen 3.4.1 (v >= 126)
Just F11 still keeps udevinfo, Ubuntu 9.04 doesn't.
It shouldn't be matter.

Argh, that's me editing the patch before checkin, and screwing it up. I
