Thread-topic: [Xen-users] xen unstable boot problem - Kernel panic - not syncing: VFS
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!

Is your initrd file called
/boot/initrd.img- 2.6.16.13-xen
or
/boot/initrd-2.6.16.13-unstable
If you give one name to mkinitrd and another name to grub, it could be the reason it doesn't work...

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.

Subject: [Xen-users] xen unstable boot problem - Kernel panic - not syncing: VFS

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
