[Xen-users] dom0 no longer showing serial console output
Running
Xen unstable on SLES10 x64. Serial output was working correctly in changeset
15837 (the xen boot output was directed to both the standard vga console and the
serial console). I have recently upgraded to changeset 16112 and now I do
not get any output on the serial console.
In my
menu.lst I have:
root (hd0,1) kernel /boot/xen.gz
com1=115200,8n1 apic_verbosity=debug module
/boot/vmlinuz-xen root=/dev/sda2 vga=0x314
resume=/dev/sda1 splash=verbose showopts debug=y
module /boot/initrd-xen
I have tried adding "console=ttyS0" but
this doesn't seem to produce any output either. The
command
echo "test" >/dev/ttyS0
errors with
-bash: /dev/ttyS0: No such device or address
but /dev/ttyS0 does
exist.
btw,
serial output does show up when I boot the SLES kernel. Its entry
is:
root (hd0,1)
kernel /boot/vmlinuz root=/dev/sda2 vga=0x314 resume=/dev/sda1
splash=verbose showopts console=ttyS0,115200n8 console=tty0
debug initrd /boot/initrd
I suspect
the xen serial console code has changed recently. Can anyone point me to some
settings that will work. Thanks
