Cloning or deploying VM from template is changing adapterType in VMDK to buslogic

Products

• VMware vSphere ESXi

Issue/Introduction

After performing a clone or deploying a VM from template the adapter type is changing in the VMDK causing a mismatch between the configured adapter in the VM and the adapterType in the VMDK descriptor file.

Environment

• vSphere 7.X
• vSphere 8.X

Cause

Reviewing the VMX and VMDK post clone operation or VM deployment from template are mismatched:

VMX:
/vmfs/volumes/<datastore>/<vm name>/<vm name>.vmx:
.encoding = "UTF-8"
config.version = "8"
virtualHW.version = "19"
vmci0.present = "TRUE"
floppy0.present = "FALSE"
numvcpus = "4"
memSize = "12288"
firmware = "efi"
tools.upgrade.policy = "manual"
sched.cpu.units = "mhz"
vm.createDate = "1767630031849385"
scsi0.virtualDev = "pvscsi"

VMDK Descriptor:
/vmfs/volumes/<datastore>/<vm name>/<vm name>.vmdk:
# Disk DescriptorFile
version=1
encoding="UTF-8"
CID=a35d0166
parentCID=ffffffff
createType="vmfs"

# Extent description
RW 272629760 VMFS "vmname-flat.vmdk"

# The Disk Data Base
#DDB

ddb.adapterType = "buslogic"
ddb.deletable = "true"
ddb.geometry.cylinders = "16970"
ddb.geometry.heads = "255"
ddb.geometry.sectors = "63"

Resolution

This behavior is working as expected.

The adapterType field is deprecated and will be removed in future releases.
