Migration/Cold Clone Linux VM Not Booting

[adamadamadam]

Hi Everyone

Im having trouble with a migration, I was wondering if anyone could throw any suggestions in or if they had seen this sort of problem before.

Migration type: Virtual to Virtual

Method: Cold Clone

Source host: VMWare Server 1

Source VM: Linux Read Hat 4

Distination Host: ESXi 4.1

Error: When VM is booted error is thrown in Linux VM OS

The cold clone works fine, as in the VM actually moves from one virtual environment to another. The problem occurs when the VM is booted.

The following error is thrown:

Uncompressing Linux... OK, booting kernel

Red Hat nash version 4.2.1.8 starting

mkrootdv: label /1 not found

mount: error 2 mounting ext3

mount: error 2 mounting none

switchroot: mount failed: 22

umount /initrd/dev failed: 2

Kernel panic - not syncing: Attempted to kill init!

Now as there is the mention of mounting in the error, I assumed this may be a file system problem, so I have posted a pic of the VM configuration.

Any help or thoughts would be greatly appreciated.

Thanks

Hi adam

You´ve migarted the VM of AMD cpu to Intel or viceversa?

The new ESX can see the LUNs?

Hi Maximenu

As I understand it CPU brand shouldnt be a problem for cold clone?

Also I believe there are no LUNs involved. It is just one VM, with three virtual HDD's attached.

I had a problem with a Linux vm on AMD processor, when i migrated to other ESX with Intel CPU, the vm dont started.

We´ve discard the storage problem.

Can you be more specific with the problem you saw? Did it throw any errors?

Did you do anything to resolve it?

[Maximenu]

Did you do anything to resolve it? I could not do anything. The Vm needed the ESX AMD

Migrate again your VM and test if you can boot it.

[adamadamadam]

Not really the answer Im looking for, but thank you for your input and advice.

Has anyone else seen such an error?

[Maximenu]

Mmmmm...you migrated the VM to new versión of ESX? or its the same versión?

[adamadamadam]

Although I really appreciate your help, Ive actually already specified this in my orignal post.

VMWare Server 1 > ESXi 4.1

From the Linux boot error image it looks like the partition labels don't match. Get a Linux Rescue CD. You may need to edit inittab and or partition labels.

Just keeping this thread alive. I will be trying this today and will report back.

RESOLVED.

Resolved this myself.

The migration creates a virtual machine with a SCSI Controller Type: BusLogic Parrellel. The OS doesnt support this, changed it to LSI Logic SAS and OS booted fine.

You can make these changes by editing the properities of the virtual machine.
