Unable to open initial console on dom0

Unable to open initial console on dom0

[anil prasad]

Hi,
I am new to Xen. I tried to use it with RHEL4 alongwith 2.6.10 fresh
linux kernel.

Dom0 kernel gets loaded but it gets struck after printing "Unable to
open initial console"

Here is my /etc/grub.conf configuration:
---------------------------------------------------Begin-----------------------------------------------
title Xen 2.0 / XenLinux 2.6.10
        kernel /xen.gz dom0_mem=131072 root=/dev/sda5 com1=9600,8n1
        module /vmlinuz-2.6.10-xen0 root=/dev/sda5 ro "console=ttyS0"
----------------------------------------------------End--------------------------------------------------

Somewhere on the web, I read that Xen causes trouble if devfs is being
used for /dev entries but RHEL 4 doesn't use devfs. I checked up
CONFIG_VT and other related configuration options in dom0 kernel which
are ok.

Any help will be greatly appreciated.
Thanks,
Anil.

Re: Unable to open initial console on dom0

Can you try using the RHEL initrd?  Add another "module" line to grub.conf 
(NOT an "initrd" line) specifying the same arguments as your standard RHEL 
initrd line.

Cheers,
Mark
