With every kernel before 6.12.x it worked fine, but current 6.12.4 it failes with error when trying to run any image (all linux). > VirtualBox can't operate in VMX root mode. > Please disable the KVM kernel extension, recompile your kernel > and reboot. > (VERR_VMX_IN_VMX_ROOT_MODE). Rebooting machine and selecting the 6.11.11 kernel, it would run everything fine. I did also, find the doing the rmmod kvm_intel did also let the VirtualBox run fine with 6.12.4? Machines that I run it on are running Fedora 40. Have 4 other machines with Fedora 41, but having tested it on those. on one machine I removed both kvm and kvm_intel, but on other just removed the kvm_intel? Both worked. Not sure what creates the /sys/modules/kvm and /sys/modules/kvm_intel? Note sure what creates these directories. Tried reinstall kernel, but the /sys/modules/kvm was not recreated? > -- > _______________________________________________ > users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx > To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx > 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/users@xxxxxxxxxxxxxxxxxxxxxxx > Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue +------------------------------------------------------------+ Michael D.
