Ok, then it comes to what the .config file contains. I
don't know hwat it SHOULD contain, as I don't know the rest of your system
setup... Since you're using basic IDE controller, it shouldn't be a problem with
that (unless you've got some weird chipset that requires a different driver).
Try booting your working Xen-version and do a lsmod, then
check that all modules listed there are also in the .../modules/2.6.16.13-xen
directory...

Oh no no, my initrd is the one as mentioned in the grub. I guess I
messed up in my first post. Sorry for that!

If
you give one name to mkinitrd and another name to grub, it could be the
reason it doesn't work...

[Xen-users] xen unstable boot problem - Kernel panic - not syncing:
VFS
Dear Mats,
I'm sure the root partition on the command line
for my vmlinuz is correct.
My grub looks like the
following:
title
Xen
3.0
root
(hd0,0)
kernel
/boot/xen- 3.0.2-2.gz dom0_mem=262144 com1=38400,8n1
sched=bvt
module
/boot/vmlinuz-2.6.16-xen root=/dev/hda1 ro
console=ttyS0
module
/boot/initrd.img-2.6.16-xen
boot
title
Xen 3.0 Unstable
root
(hd0,0)
kernel
/boot/xen-3.0-unstable.gz dom0_mem=262144 com1=38400,8n1
sched=credit
module
/boot/vmlinuz-2.6.16.13-xen root=/dev/hda1 ro
console=ttyS0
module
/boot/initrd.img-
2.6.16.13-xen
boot
title
Ubuntu, kernel
2.6.12-9-686
root
(hd0,0)
kernel
/boot/vmlinuz-2.6.12-9-686 root=/dev/hda1 ro quiet
splash
initrd
/boot/initrd.img-2.6.12-9-686
savedefault
boot
However,
the problem is only with xen-unstable. Xen 3.0 boots fine and is working
normally! Also I am a newbie to all this so could'nt really get you
regarding the drivers!
Please let me know if you need me to provide
any additional information or append a config file!
Regards,
Hardeep Singh

Usually, this is becuase you don't have the right drivers set up in
the .config for your Linux kernel (either as modules or as builtin -
if they are built in, you wouldn't need an initrd). Or you're not
specifying the right root partionion on the command-line for your vmlinuz
when you boot it... It's impossible to say which one of those it is
without knowing more about your setup, both what
hardware [including, for example, what partitions are used for
what] and what the commands in grub.conf are.
Very
likely is that you have either a SATA or SCSI drive, and the drivers
for your SATA/SCSI controller isn't configured into the kernel .config
file. Or you're using an unusual file-system on your root-drive, and this
file-system isn't supported by the default .config.
And
yes, mkinitrd is different for different distributions of Linux, so one
set of arguments for one distribution doesn't necessarily work for another
distritution :-(
I hope this helps.

Hi all,
I'm trying to install xen-unstable on ubuntu. I
downloaded the tarball from the download page. Everything goes on fine
until the compilation. However when I boot xen-unstable this the error I
get:
Kernel panic - not syncing: VFS: Unable to mount root fs
on unknown block (0,0)
I guess this has something to do with the
ram disk image. What I am doing currently is:
depmod -F
/boot/System.map-2.6.16.13-xen 2.6.16.13-xen
mkinitrd -o
/boot/initrd-2.6.16.13-unstable 2.6.16.13-xen
The readme
however says to do this:
mkinitrd -v -f --with=aacraid
--with=sd_mod --with=scsi_mod initrd-2.6.16.13-xen.img
2.6.16.13-xen
But when I do this, mkinitrd gives an error regarding
illegal options. The only ones it provides are:
-d
confdir Specify an
alternative configuration
directory.
-k
Keep temporary directory used to make the image.
-m command Set
the command to make an initrd image.
-o
outfile Write to
outfile.
-r
root
Override ROOT setting in mkinitrd.conf.
Please help me on how to go
about booting xen-unstable. I desperately need to get it
working!
Regards,
Hardeep
