I am not sure if it is okay. But I think you can try vmlinuz-2.6.16-1.2080_FC5xenU which comes from another Xen RPMs. >memory = 128 >name = "fedora.fc4" >nics = 1 >dhcp = "dhcp" >disk = ['file:/xen/fedora/fedora.fc4.img,sda1,w', >'file:/xen/fedora/fedora.swap,sda2,w'] Although I think this config won't cause the error you meet, I suggest firstly let us try only use 1 disk for "/" and remove the swap disk config in here and fstab. If it can boot, then try to add swap back. :) >root = "/dev/sda1 ro" > >[root@muratisik fedora]# mount -o loop fedora.fc4.img /mnt/ > >[root@muratisik fedora]# cat /mnt/etc/fstab ># This file is edited by fstab-sync - see 'man fstab-sync' for details >/dev/sda1 / ext3 defaults 1 1 >/dev/sda2 none swap sw 0 0 >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 > >[root@muratisik fedora]# umount /mnt/ > >[root@muratisik fedora]# xm create fedora.fc4.xen.cfg -c > >and the error appears: > >... >md: ... autorun DONE. >VFS: Cannot open root device "sda1" 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) > [<c011c42c>] panic+0x3c/0x190 > [<c03c6a5c>] mount_block_root+0x19c/0x1aa > [<c03c6ab3>] mount_root+0x49/0x4e > [<c03c6b78>] prepare_namespace+0xc0/0xf1 > [<c0102267>] init+0x23e/0x2fe > [<c0102029>] init+0x0/0x2fe > [<c01029ad>] kernel_thread_helper+0x5/0xb > > >Then I changed both image's fstab to hda1 and hda2 , also editted cfg to >match hdas. and I get the same error. any ideas? is there any more >information (log, config, debug vs.) I can supply? Maybe you can try another thing. Is your image file's dev/ folder empty? If so, please mount the xenU image file, and copy your local /dev/* to image file's dev/ . My xenU dev/ has all device file prepared. ;) > >have a nice day. > Best Regards, Yongkang (Kangkang) 永康
