We recommend that customers update to the latest version from their chosen channel following the instructions at https://docs.xenserver.com/en-us/xenserver/8/update or https://docs.xenserver.com/en-us/xenserver/9/update We have also published an updated Terraform provider, version 0.3.0. We recommend that customers using the XenServer Terraform provider upgrade to that version, either by using standard Terraform tooling or by downloading the updated version directly from https://github.com/xenserver/terraform-provider-xenserver/releases.
