Description

I'm trying to manually clone a VM with a RDM disk attached but when I try to create the new VM the process fails with vim.fault.InvalidDiskFormat. The process is as follows.

  1. Get the old VM and copy the RDM specs
  2. Shut the old VM down
  3. Use the previous obtained RDM specs to create a new RDM mapping on the new VM

I've included the hostd.log and the code that creates the new RDM mapping for the new VM.

Is there something I'm missing, the vSphere API isn't really clear if I need to do some additional steps before readding the RDM. Any help would be appreciated.

Research direction

Start with the RDM creation code in the issue and the accompanying hostd.log, focusing on the VirtualDeviceSpec and RawDiskMappingVer1BackingInfo values sent during new VM creation. Compare the submitted disk specification with the logged ConfigSpec and determine what change is needed for the new VM creation to complete without vim.fault.InvalidDiskFormat.
