[Clonezilla-live] Restoring a CentOS disk to VmWare : help needed

[Matthieu G. <mgw...@fa...>]

For the record : the problem was that the default disk emulation
of vmware (at least Fusion, mac) is SCSI, while the originating
machine was an IDE one. Looks like centos wasn't equipped with
the necessary drivers to handle the SCSI interface.

Solution 1 : change the interface type to IDE and restore again
Solution 2 : add the drivers needed (not tried)

Thanks for the help Steven !

Yes, vmlinuz will be loaded, then when initrd.img is loaded, and
when it tries to find the root partition, it can not find, since
SCSI driver is not found in initrd.img, so it won't be able to
mount the root partition on SCSI disk. Therefore it shows you
kernel panic.

  Would it boot anyway until the Kernel panic ? Even without
  those drivers ? I'll try to check if they are presents and to
  install them if needed.

  Nope, the contrary :

  * disk image taken on Physical IDE --> restored on vmware IDE

  That makes sense... Since maybe your initrd of OS taken from
  IDE disk does not include the driver for SCSI device.

  Hi Matthieu,

  Did you mean you installed CentOS on your IDE in the VMware
  machine, and it works ?

  But if CentOS is installed on SCSI disk, Clonezilla failed to
  restore ?

  Steven,

  I tried using an IDE drive emulation on the VMware machine :
  IT WORKS !

  Any idea ? Should it work ? How could I make it work in SCSI
  anyway ?

  Thanks

  Matthieu

  Hi Steven,

  Thanks for your answer. I didn't saw any other error messages,
  but it is possible that I missed one of them... Is there a log
  of the activities written somewhere on the ramdisk ?

  Regarding the image dir : it is stored on an external hardrive
  that I access through Samba at restore time.

  Here is the result of the find command :

  Thanks

  Maybe a lead : the original physical machine is equipped with
  IDE / ATA drives. Vmware presents a SCSI interface... Could it
  be the origin of the problem ?

  Hi,

  I'm trying to restore a physical installation of Centos to a
  VMWare

  virtual machine.

  I received the dreaded "Running:

  grub-install-no-floppy-root-directory=/tmp/hd_img.QiFQFv
  /dev/sda

  grub-probe: error: Cannot open '/boot/grub/devise_map'

  /usr/sbin/grub-install: line 374: [: =: unary operator
  expected" error

  message.

  This is a harmless error. Check this:

  [5]http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=513216

  BTW, when you saved or restored the image, did you see any
  error

  messages other than the above one ?

  How about the image dir ? Could you please run:

  find /home/partimag/$YOUR_IMAGE -print

  (Replace $YOUR_IMAGE with your image name)

  then post the results ?

  Steven.

  Anyhow, when I try to boot the machine, I received a Kernel
  Panic :
