In a prior post titled More Linux Musings ( /2022/11/20/more-linux-musings/ ) I made the comment that Alma Linux 9 would not successfully build the Parallels Tools, and thus the necessary kernel modules, for full Parallels integration. That was Alma Linux version 9. When Alma Linux 9.1 was released I updated my version 9 installation to 9.1. As hope springs eternal, I tried to install Parallels’ Tools once again within the Alma Linux 9.1 VM. Lo and behold the tools built. I thus have a fully integrated Alma Linux 9.1 with my MacBook Pro. This is a Good Thing as I have need, from time to time, to try things out within a “professional” Linux release that matches RHEL 9, without having to jump through RedHat’s hoops to install a RHEL 9.x VM.

I don’t know exactly what happened; Parallels did not upgrade, but Alma Linux did, which seemed to fix this problem.
