I've been given a folder of a VM (with .vmdk, .vmx, ...), created and used in VMWare Workstation. I want to use it on my VMWare ESXi.

How do I correctly import the VM?

I've tried to import it, by copying the folder to the ESXi datastore, then 
`Create/Register VM`, `Register an existing virtual machine` and finally choose the `.vmx` file of the copied folder.

The adding of the VM appears to work just fine, but when I try to start it, ESXi states:

```
Failed to open disk scsi0:0: Unsupported or invalid disk type 7. Ensure that the disk has been imported.
Unable to create virtual SCSI device for scsi0:0, '/<disk-store>/import/<the-workstation-folder>/<target-vm>.vmdk'
Module DevicePowerOn power on failed.
Failed to start the virtual machine.

```

In the settings of the new ESXI VM, I see that the path is correct and the virtual disk file is really in that location.

Is there another way to import the VM? Do I have to modify the disk settings on the ESXi?

*I have no access to VMWare Workstation, where the VM was originally created/used.*
