Hello everyone,I'm having an issue migrating an OLD debian 3.0 linux server (2.4.18 kernel) to an HVM domU. I'm using Xen 3.3.0 compiled from source. Here's the process I took: 1. Carve out a chunk of space from an LVM Volume group 2. Create and boot from a Debian live CD ISO 3. Fdisked the LV into 2 partitions /dev/hda1 (OS) /dev//hda2 (SWAP) 4. Formatted /dev/hda1 as ext3 and /dev/hda2 (swap) 5. Mounted /dev/hda1 /mnt/ 6. Restored from a full backup my physical server onto /mnt 7. chroot-ed /mnt8. Edited lilo.conf and fstab to match what I have, ran lilo and everything looks good. 9. Run lilo and rebootWhen I reboot I get the following errors about reisersf -- which makes no sense considering I'm using ext2/ext3: EXT3-fs unsupported inod size: 256read_super_block: can't find a reiserfs filesytem on (dev 03:01, block 64, size 1024) read_super_block: can't find a reiserfs filesytem on (dev 03:01, block 8, size 1024) Kernel panic VFS: Unable to mount root fs on 03:01When I boot the Debian Live-CD it looks like the PIIIX3 IDE controller is detected and hda is QEMU HARDDSIK. Again, this doesn't make any sense, to me, since I'm using ext2/ext3 fs. But I am wondering if it has anything to do with OLD e2fs tools.. or maybe if there's a driver bug with a 2.4.18 kernel and the IDE driver. This old server has everything compiled into the kernel, no modules. /etc/lilo.conf for domU: lba32 install=/boot/boot-menu.b map=/boot/map vga=normal default=Linux image=/vmlinuz label=Linux read-only image=/vmlinuz.old label=LinuxOLD read-only optional Modified /etc/fstab file for domU: /dev/hda1 / ext2 errors=remount-ro 0 1 /dev/hda2 none swap sw 0 0proc /proc proc defaults 0 0 Config File: kernel = '/usr/lib/xen/boot/hvmloader' builder='hvm' boot='dc' memory = 3072 name = "newt-test" vif = [ ' mac=aa:00:ef:49:c1:23 ' ] device_model = '/usr/lib/xen/bin/qemu-dm' # dhcp = "dhcp"disk = [ 'phy:/dev/vg01/newt-test,hda,w','file:/etc/xen/binary.iso,hdc:cdrom,r' ] vcpus = 1 root = "/dev/hda1 ro" extra = "xencons=tty" vnc=1 vnclisten='0.0.0.0' vncpasswd='xxxxxxxxxxx' apic = 1 acpi = 1 vncdisplay=4 vncunused=1 Thanks for any suggestions/pointers. --Jim _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users
