      .Persistent memory device passthrough cannot be used in RHEL 10

      Because the `nvml` package was removed in RHEL 10, persistent memory (`pmem`) device passthrough cannot be used anymore. `pmem` device passthrough allows a virtual machine to directly access a host's physical persistent memory hardware with minimal emulation overhead.

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

      nvml package will go away in RHEL10. That means libpmem library will not be available. Disable pmem device passthrough in qemu.
