Xen serial console on Bladecenter virtual serial port

Xen serial console on Bladecenter virtual serial port

[Rich Persaud]

Has anyone accessed Xen or the dom0 Linux serial console on the virtual 
serial port of a Bladecenter blade via Serial-over-LAN?

Was able to see bios boot screen and access grub boot menu, but only the 
first few characters of the kernel boot sequence are shown, then nothing.

I've got SOL working with Xen on my Bladecenter and saw the similar problem
before. Here are a couple of things you might want to check:

1. Check if the serial ports are turned on in BIOS and the "Remote Console
Active" should be enabled.
2. Check boot file modification. I use GRUB. Here are the modification I
made:
      Added lines:
            serial --unit=1 --speed=19200
            terminal --timeout=10 serial console
      Modified line:
            kernel /xen,gz dom0_mem=512072 com2=19200,8n1 console=vga, com2
(I used console=ttyS1 before. But it did not work for me for some reason so
I changed to com2. )
3. Add ttyS1 to /etc/securetty.

Hope it helps.
