Bug description:
  KVM: Secure Execution guest dump encryption with customer keys -
  s390-tools part

  Description:
  Hypervisor-initiated dumps for Secure Execution guests are not helpful because memory and CPU state is encrypted by a transient key only available to the Ultravisor.  Workload owners can still configure kdump in order to obtain kernel crash infomation, but there are situation where kdump doesn't work. In such situations problem determination is severely impeded. This feature will implement dumps created in a way that can only be decrypted by the owner of the guest image and be used for problem determination.

  Request Type: Package - Update Version
  Upstream Acceptance: In Progress
  Code Contribution: IBM code
