    Hi, Somehow it seems the error hasn't been reported yet, or I'm unable to find the right thread.
    I installed rhel8 (beta) and tried to install the parallel tools, but it failed.

    . as the output states, it's about kernel 4.18.

    If some workaround is available (which I haven't found), can one please point me to it? otherwise, if others encounter the same issue, it might be the tools aren't ready yet for the 4.18 kernel.

    Thanks for any pointers to the solution, greatly appreciated.

    No, I think it is the other way around -- with 14.1.3 Parallels tried to address the kernel 5.x support and changed the source code to be kernel 4.20+ friendly. You fell a victim of that change :). If I were you, I would compare the sources of prl_vmnet.c between, say, 14.0 (where old kernels were supported properly) and 14.1.13 and would make the adjustments accordingly.

    Consequently, translation to a machine address fails, and an error log occurs.
