      .CCA in ARM virtual machines is available as a Technology Preview
      As a Technology Preview, you can enable Confidential Compute Architecture (CCA) in RHEL 10.1 virtual machines (VMs). CCA, built on top of Realm Management Extension (RME), helps to maintain data privacy while it is in use within a virtual machine.

      Currently, CCA can only be enabled in ARM VMs as a Technology Preview and not in a RHEL host.

      The EPIC tracks the introduction of basic support for CCA on guest on virt-arm. The following series needs to be downstream:

      [PATCH v7 00/11] arm64: Support for running as a guest in Arm CCA

      We need to investigate how this can be tested. At least non regression testing must be done, at bare minimum.
