[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.
