Hi, Rodrigo >VFS: Cannot open root device "sda7" 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) This message is shown when disk configuration is wrong. > >My "new" domU configuration: > >name="vm01" >#kernel="/boot/efi/efi/debian/vmlinuz-2.6.16.13-xenU" >kernel="/boot/vmlinuz-2.6.16.13-xenU" >root="/dev/sda7 ro" >memory=128 >disk=['file:/vserver/images/vm01.img,sda7,w','file:/vserver/images/vm01- >swap.im$vif=[''] I look like the above disk configuration is wrong... And please use hda(not use sda) in domU. Can you make sure that /etc/fstab in domU's image and disk =[ 'xxx' ] in domU config are correct? Please see my old mail. /etc/fstab in domU's image and disk =[ 'xxx' ] in domU config are the same one. >--------------------------------- >Make OSimg for DomU > 1. make file > # dd if=/dev/zero of=/root/rhel4.img bs=1M count=4096 > # mke2fs -F -j /root/rhel4.img > # mount -o loop /root/rhel4.img /mnt > # cp -ax /{dev,var,etc,usr,bin,sbin,lib} /mnt > # mkdir /mnt/{root,proc,sys,home,tmp} > > 2. modify DomU's fstab > # vi /mnt/etc/fstab > /dev/hda1 / ext3 defaults 1 1 <-----this one > none /dev/pts devpts gid=5,mode=620 0 0 > none /dev/shm tmpfs defaults 0 0 > none /proc proc defaults 0 0 > none /sys sysfs defaults 0 0 > > 3. make config of DomU > # vi /etc/xen/rhel4 > kernel = "/boot/efi/efi/redhat/vmlinuz-2.6.16.13-xen" > memory = 384 > name = "rhel4" > nics=0 > disk = [ 'file:/root/rhel4.img,hda1,w' ] <-------this one > root = "/dev/hda1 ro" > extra = "3" > Best Regards, Akio Takebe _______________________________________________ Xen-ia64-devel mailing list Xen-ia64-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-ia64-devel
