[Xen-devel] Xen serial console on Bladecenter virtual serial port
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.

Re: [Xen-devel] Xen serial console on Bladecenter virtual serial port
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.
