What version of VirtualBox are you running? VirtualBox introduced initial support for Linux kernel 6.19 in VirtualBox 7.2.6, released on January 28, 2026. This version includes the necessary updates to handle changes to low-level CPU functions and kernel module compilation required for the 6.19 kernel. Key Details on 6.19 Support: * Initial Support: VirtualBox 7.2.6 is the first release to provide "initial support" for the 6.19 kernel (which was officially released on Feb 8, 2026). * Fixes: The update specifically addresses issues with compiling kernel modules, which arise from stricter handling of low-level CPU functions (such as the CR4 register) moved into a protected namespace in the 6.19 kernel. This topic: https://forums.virtualbox.org/viewtopic.php?t=114417 Reports that the module build issue is fixed in 6.19.06 but I have not verified this. -- _______________________________________________ users mailing list -- [email protected] To unsubscribe send an email to [email protected] Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/[email protected] Do not reply to spam, report it: https://forge.fedoraproject.org/infra/tickets/issues/new
