Nutanix Foundations Fails to Image

I have been working on a project to change from a six node Nutanix VMware cluster to a Hyper-V one, simple I thought. Here was my intended method:

  • Reimage to Hyper-V using the Phoenix package and the Foundations VM
  • Create a new cluster.
  • V2V all the VMs using SCVMM
  • Destroy the old cluster
  • Reimage those nodes and add to the...
