Issue/Introduction

Cloning a VM from one vCenter to another fails with error "Invalid datastore path '[DATASTORE_NAME] <VM_NAME>_2/<VM_NAME>-000001.vmdk'." if disk or hardware configuration changes are made to the new VM as part of the cloning process.

vpxd logs on the destination vCenter server similar to below:

Environment

VMware vSphere ESXi 7.0

Cause

This is due to the use of the "VirtualMachineConfigSpec" API to apply hardware changes to a cloned virtual machine.

Resolution

There is no resolution for this issue currently.

Workaround:
Do not make any hardware changes to the new VM as part of the clone process. Create the clone first, then make hardware changes afterward.
