What I eventually discovered: I was running kernel 5.14.0-142.el9.x86_64 which was the default kernel version installed with the fresh .iso It errored out every time, the line that popped out in the log file was: {{{ fatal error: drm/drm_irq.h: No such file or directory }}} I was able to get VBox additions by installing an older kernel version and booting to that. {{{ yum install kernel-5.14.0-124.el9 kernel-devel-5.14.0-124.el9 }}} kernel-5.14.0-124.el9 was the oldest kernel version available in yum, but I was able to install VBox additions running that version.
