Hi all,

All cloned guests can't boot

Warning:
Timed out waiting for device dev-disk-by\x2did-ata\x...2dpart1.device.

Found following 2 threads:

Why did you clone the vm? How did you clone the vm? Usually you just copy the entire vm instead of a clone.

Yes, a normal computer that is cloned could have specific hardware that is mentioned in a few places. One is grub, another is fstab. A rule before clone is to make the terms generic like /dev/sda1 or such instead of my name or uuid.

You'll have to correct all entries that mention the old system to either generic or the new name/uuid or other. A live cd should help correct.

The openSUSE VM was cloned on the same PC. The cloned VM has booting problem. I tried at least 3 times creating 3 cloned VMs.

However the strange thing is no problem on cloning Debian 7.3.1/LinuxMint16/Ubuntu12.04, all VMs cloned without booting issue.

Opensuse uses specifics in their boot and fstab. Change to generic or correct them to the new system.

Hi all,

Problem solved as follow;

Start the VM with live-kde-opensuse13.1 ISO

Start Terminal

linux@linux:~> su

# fdisk -l

Code:

Disk /dev/sda: 42.9 GB, 42949672960 bytes, 83886080 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk label type: dos
Disk identifier: 0x0002efa7

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *        2048      819199      408576   83  Linux
/dev/sda2          819200    83886079    41533440   8e  Linux LVM

Mount LVM

# pvs

Code:

  PV         VG     Fmt  Attr PSize  PFree
  /dev/sda2  system lvm2 a--  39.61g 8.00m

# lvdisplay /dev/system

Code:

....   
  --- Logical volume ---
  LV Path                /dev/system/root
  LV Name                root
  VG Name                system

# mount /dev/system/root /mnt

# ls /mnt/

Code:

bin   dev  home  lib64       media  opt   root  sbin     srv  tmp  var
boot  etc  lib   lost+found  mnt    proc  run   selinux  sys  usr

# cp /mnt/etc/fstab /mnt/etc/fstab.ORIG_20140103

# nano /mnt/etc/fstab
change the line;

Code:

/dev/disk/by-id/ata-VBOX_HARDDISK_VBef165ce6-8bf1a0de-part1 /boot  ext4  acl,user_xattr 1 2

as;

Code:

/dev/sda1 /boot  ext4  acl,user_xattr 1 2

Shutdown the VM and remote the live-kde-opensuse13.1 ISO

Start VM. Now it can boot without problem.

Thanks

Edit
====
To avoid the step mounting the LVM do as follow;

After booting the Live-CD

Kmenu -> Applications -> System -> File Manager -> File Manager-Super User Mode

Then it can directly edit the "fstab" file there.
