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

I just migrated to fc3, and tried to install xen-2.0.6. But when I tried
to boot up xen0, I got the error message "unable to open an initial
console" and the system hangs after that.

I know this is a FAQ and already checked the XenFaq 5.2

But the solution put there only works for 2.6 kernel.

I still need to use 2.4.30-xen0, which doesn''t work with initrd I can
get
from the website and fc3. I guess that''s because those initrd files are
just for 2.6. Question is how to get a usable 2.4 initrd? Is there any way
to get around this?

Thanks in advance for advices1

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

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

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

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.

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

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

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.

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

Thanks for all follow-ups. I tried Nitin''s solution, it worked for me.
Now
I can boot 2.4.30-xen0 successfully. Since this approach is quite simple,
we can probably follow that. The only issue is that Nitin''s description
seems to be wrong. Instead of doing "cp /dev/* /mnt/*", we might need
to
do "cp /dev/* /mnt/dev/".
