[Xen-users] Xen boot failed while mount root FS.

["Taylor Lee" <taylorl@xxxxxxxxxxxx>]

Hi,Guys 

I installed Xen3.0.2 on CentOS4.2 platform with xen-3.0.2-src.tgz or
xen-2.0.7-install-x86_32.tar,but I got below error during boot from Xen
kernel:

VFS: Cannot open root device "/" or unknown-block(0,0)
Please append a correct "root=" boot option
Kernel panic - not syncing: VFS: Unable to mount root fs on
unknown-block(0,0)

any idea for this issue,it is really appreciated!

More,grub.conf file :

default=0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title CentOS-4 i386 (2.6.9-22.ELsmp)
        root (hd0,0)
        kernel /vmlinuz-2.6.9-22.ELsmp ro root=LABEL=/ rhgb quiet
        initrd /initrd-2.6.9-22.ELsmp.img
