RE: [Xen-devel] xen bootup problem: unable to open an initial console

[Sheng S Lu <shenglu@xxxxxxxxxx>]

Yeah, I wrote the mail with my memory.
I check it this time, and find that my old version is 2.6.9-5.EL. Nahant
kernel

Then, I think Zhao Xin has to make an
initrd image by himself. Some old Linux kernel support command "mkinitrd",
some version do not have the command, but there will be an introduction
file in "Documentation" directory. I've not tried it myself.

Another way is disable udev and make
a /dev/console device as you have told.

Probably you are not using
Fedora Core 3. I see the initial console issue even with initrd on FC3.

I've also met the problem when I tried to boot up XEN in 2.6.x. And because
I'm using udev, the problem persisted even I created a /dev/console in
my old kernel. 

Then, I copied the initrd line from the original kernel, just modified
the "initrd" keyword to "module". It goes to work,
and I have not met any other problem because initrd image is only used
while booting up. 

Though my kernel is 2.6.11.12, my initrd is still an old version. I do
not sure my solution is good, but it works. Please correct me if it is
not a right way.

One solution to it is.
                1. Run with FC3
kernel (not xen)
                2. mount root again
to /mnt
                3. cp -ar /dev/*
/mnt/*
                4. now reboot into
xen.

The issue is /dev/console device file is not present, udev should create
it, if you are not using udev, you need to have this file.

Thanks & Regards,
Nitin
