Disk format using SCSI controller and ddb.adapterType

Post by cesarjorgemartinez »

Hi,

I use one image with disk format using SCSI controller with Linux guest.
Then, if I see the image image in editor, shown the following:

ddb.adapterType="ide"

Sould it be?:
ddb.adapterType="lsilogic"

That sounds like you're looking at a VMDK file, a raw VMDK file, is that right?

Hi,

It is a VMDK file format that I create when create a new VM.
Configuration->SCSI Controller (lsilogic)->MyVM.vmdk

It isn't clear to me what the question is here?

Yes, a VMDK includes a readable "descriptor" which will be embedded in the header. VirtualBox is not bound to honor everything that header might contain, e.g. in VirtualBox the .vbox file determines what controller a drive is attached to, not the VMDK header. Typically the image type, drive geometry and UUIDs will be honored.

Hi,

The ask is if it is a error or not, when a vmdk file is created using scsi controller, then the line ddb.adapterType="ide", seems wrong.
Then, it is not an error?

I believe I already answered that question.

i.e. it doesn't matter what the header says. Did VirtualBox even create this VMDK? If not then it has no control over who put what in the embedded header: which incidentally never changes after the VMDK is created.
