[Xen-devel] Serial console??

[Nicholas Lee <emptysands@xxxxxxxxx>]

I'm trying to setup a login getty session via the console with Xen 3.0
so I can access it via the v20z SP console.

I've managed get bios, grub and linux boot console access, but getty
refuses to start.


I'm wondering if anyone has any pointers.

I note this particular error in dmesg:
"WARNING: Failed to register Xen virtual console driver as 'ttyS0'"

===

nic@wuwei:~$ grep xen /boot/grub/menu.lst
  kernel /xen-3.0-devel.gz dom0_mem=262144 com1=38400,8n1
  module /vmlinuz-2.6.12-xen0 root=/dev/sda3 ro console=ttyS0,38400
console=tty0 hda=none hdb=none


from dmesg:
