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. excerpt from the installer Code: 2019-04-06T01:39:27+0200: Started installation of Parallels Guest Tools version '220.127.116.11485' Error during report about start installation of parallels tools.

Please go to /var/log/parallels-tools-install.log for more information. 2019-04-06T01:39:37+0200: Exiting with code 1 I'm running the most recent version of Parallels Desktop (with tools v 18.104.22.168485) . 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.
