[Xen-users] 3.4-testing : Kernel panic on bootup (mount: could not find filesystem /dev/root/)

["Madhu Venugopal (vmadhu)" <vmadhu@xxxxxxxxx>]

Hi,

I installed XEN 3.4-testing version without much problems in CentOS 5.3
running on quadcore Intel Nahelam processors using the following
installation
steps (as in the README) :

<steps>
hg clone http://xenbits.xensource.com/xen-3.4-testing.hg`
cd xen-unstable.hg
make world
make install
make linux-2.6-xen-config CONFIGMODE=menuconfig
make linux-2.6-xen-build
make linux-2.6-xen-install
depmod 2.6.18.8-xen
mkinitrd -v -f --with=ahci --with=sd_mod --with=scsi_mod --allow-missing
initrd-2.6.18-xen.img 2.6.18.8-xen
cp initrd-2.6.18-xen.img /boot
</steps>

After the installation, I updated the grub with the following entry :

<grub.conf>
title  Xen 3.4.2
        root (hd0,0)
        kernel /xen.gz loglvl=all guest_loglvl=all vtd=1 iommu=1
        module /vmlinuz-2.6.18.8-xen root=LABEL=/ apic=debug maxcpus=8
        module /initrd-2.6.18-xen.img
<grub.conf>
But during the bootup, I see Kernel panic with the only error above that
being :

<error>
mount: could not find filesystem /dev/root/
setuproot: moving /dev failed: No such file or Directory
no fstub.sys, mounting internal defaults
setuproot: error mounting /proc:No such file or directory
</error>

Is it an error in partition ? or a Grub entry error ?
Or an installation error ?

Can someone help me ?

Thanks,
Madhu
