VB host kernel drivers fail to build on CentOS 8 Stream kernel 4.18.0-338

Reported by: jcbollinger Owned by:

Keywords: kernel driver Cc:
Guest type: all Host type: Linux

Description

Building the host kernel drivers succeeds with with CentOS 8 Stream kernel 4.18.0-315.el8.x86_64 and earlier, but fails with kernel 4.18.0-338.el8.x86_64. The issue appears to be related to issues #19644 (which relates to a newer base kernel version) and #20488 (which relates to the Guest Additions, not the host drivers), both associated with the symbol map_vm_area no longer being exported by the kernel.

This was initially observed with VirtualBox 6.0, but it still occurs with VirtualBox 6.1.26, as installed via the official VirtualBox-6.1-6.1.26_145957_el8-1.x86_64 RPM.

The relevant excerpts from /var/log/vbox-setup.log appear to be:

Hi jcbollinger,

I think this issue has already been fixed. Could you please try one of the Latest 6.1.x test builds at https://www.virtualbox.org/wiki/Testbuilds?
