Public bug reported: When installing the Virtualbox-dkms package, the modules compile but at modpost time, the following error prevents to successfully install the DKMS module.
================================== ERROR: modpost: module vboxdrv uses symbol cr4_update_irqsoff from namespace module:kvm,kvm-amd,kvm-intel, but does not import it. ERROR: modpost: module vboxdrv uses symbol cr4_read_shadow from namespace module:kvm,kvm-amd,kvm-intel, but does not import it. ERROR: modpost: module vboxdrv uses symbol __flush_tlb_all from namespace module:kvm,kvm-amd,kvm-intel, but does not import it. ================================= Reading around, it seems like the Kernel started to be stricter about what can be manipulated at low level, certain low-level CPU functions—like manipulating the CR4 register or flushing the TLB have been moved into a protected Symbol Namespace reserved strictly for KVM. An upstream fix seems to be present here https://github.com/rpmfusion/VirtualBox-kmod/commit/ec4795b37621 Will backport and test the resulting DKMS module if the patch succeed to build and deploy. ** Affects: virtualbox (Ubuntu) Importance: Medium Assignee: Alessio Faina (alessiofaina) Status: In Progress ** Affects: virtualbox (Ubuntu Resolute) Importance: Medium Assignee: Alessio Faina (alessiofaina) Status: In Progress ** Also affects: virtualbox (Ubuntu Resolute) Importance: Undecided Status: New ** Changed in: virtualbox (Ubuntu Resolute) Assignee: (unassigned) => Alessio Faina (alessiofaina) ** Changed in: virtualbox (Ubuntu Resolute) Importance: Undecided => Medium ** Changed in: virtualbox (Ubuntu Resolute) Status: New => In Progress -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2143821 Title: Virtualbox-dkms doesn't compile in Resolute 6.19 and 7.0 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/virtualbox/+bug/2143821/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
