      .pmem device passthrough has become deprecated

      With this update, the non-volatile memory library (`nvml`) packages have become deprecated, and will be removed in a future major version of RHEL. As a consequence, when the package removal occurs, it will no longer be possible to pass persistent memory (`pmem`) devices to the virtual machines (VMs). Note that emulated NVDIMM devices backed by volatile memory or files will still be available, but will not be possible to configure as persistent.

      What were you trying to do that didn't work?

       

      nvml is going away in RHEL10. We need to figure out its impact on QEMU and put appropriate deprecation notice in RHEL9 release notes.
