Convert VMware Fusion VM to ESXi based VM

There are occasions that we need to create custom built Linux VMs on behalf of our clients. Forexample, we may build a Linux VM that has all the best practices for 12c Oracle database or a 12c Weblogic Server. We sometimes do this in VMware Fusion or in vSphere/ESXi config.
In this example we will showcase how we migrate VMs built in Fusion to a ESXi based environment.
In this example, it is assumed that the Linux VM is been pre-created in VMware Fusion.
My VMware Fusion runs on MAC OsX 10.9.5

The key tool in this migration/conversion is called vmware-vdiskmanager, and is located in the following directory:
/Applications/VMware\ Fusion.app/Contents/Library

vmware-vdiskmanager has the following capabilities (as per Help)

NitinV$ ./vmware-vdiskmanager -h

VMware Virtual Disk Manager - build 1945692.
Usage: vmware-vdiskmanager OPTIONS |
Offline disk manipulation utility
Operations, only one may be specified at a time:
-c : create disk. Additional creation options must
be specified. Only local virtual disks can be
created.
-d : defragment the specified virtual disk. Only
local virtual disks may be defragmented.
-k : shrink the specified virtual disk. Only local
virtual disks may be shrunk.
-n : rename the specified virtual disk; need to
specify destination disk-name. Only local virtual
disks may be renamed.
-p : prepare the mounted virtual disk specified by
the volume path for shrinking.
-r : convert the specified disk; need to specify
destination disk-type. For local destination disks
the disk type must be specified.
-x : expand the disk to the specified capacity. Only
local virtual disks may be expanded.
-R : check a sparse virtual disk for consistency and attempt
to repair any errors.
-e : check for disk chain consistency.
-D : make disk deletable. This should only be used on disks
that have been copied from another product.

Other Options:
-q : do not log messages

Additional options for create and convert:
-a : (for use with -c only) adapter type
(ide, buslogic, lsilogic). Pass lsilogic for other adapter types.
-s : capacity of the virtual disk
-t : disk type id

Disk types:
0 : single growable virtual disk
1 : growable virtual disk split in 2GB files
2 : preallocated virtual disk
3 : preallocated virtual disk split in 2GB files
4 : preallocated ESX-type virtual disk
5 : compressed disk optimized for streaming
6 : thin provisioned virtual disk - ESX 3.x and above

Below is the command I ran to convert my Linux VM (Openfiler) to ESXi vmdk:
/Applications/VMware\ Fusion.app/Contents/Library/vmware-vdiskmanager -r OpenFiler1.vmwarevm/Virtual\ Disk.vmdk -t 4 /Volumes/Oracle-images\ 1/LinuxStones/linuxStones.vmdk
Creating disk '/Volumes/Oracle-images 1/LinuxStones/linuxStones.vmdk'
Convert: 100% done.

Virtual disk conversion successful.

ls -l ~/LinuxStones

linuxStones-flat.vmdk
linuxStones.vmdk
Linux66_StonesVT.ova

This conversion produces two files.
Once the vmdk and flat.vmdk files are generated, the next step is to import these into ESXi. I used vSphere client to execute this workflow:
1. Create a new VM, using the usual method; e.g., File->New->Virtual Machine->Custom-> Choose Datastore location
2. Choose Virtual Machine Version -> Guest CPU/Memory/Network/SCSI controller settings -> Select “Do Not Create Disk” -> Finish
3. Go back to VM Configuration-> Datastore -> Browse DataStore -> Upload
4. Upload .vmdk and -flat.vmdk
5. Go back to VM configuration (Virtual Machine Properties) -> Add -> Device Type (Hard Disk) -> “Use an existing virtual disk”
6. Locate the datastore and select the existing disk -> Finish -> OK
7. Startup VM
