Description
When using the vsphere-iso plugin with a local iso that you want to upload to vsphere it defaults to a fixed location for the packer_cache at the root of the datastore
If you do not have write perms at the root of the datastore it fails as it cannot create a packer_cache directory to upload the iso to
packer build -debug -on-error=ask .
Debug mode enabled. Builds will not be parallelized.
vsphere-iso.rhel8: output will be in this color.
