I just upgraded to 25.04 and there was an issue with VirtualBox: VBoxManage: error: VirtualBox can't enable the AMD-V extension. Please disable the KVM kernel extension, recompile your kernel and reboot (VERR_SVM_IN_USE) there was a fix here: https://superuser.com/questions/1845776/virtualbox-cant-operate-in-vmx-mode |

Thanks. I found another page with the sudo modprobe -r kvm_amdbut it had a different file to modify and a different line to add for a permanent fix. I shall try the one from that link. Really the kernel developers and the VBox people should get together to sort this out so users don't need to do this. |

Have you tried "module_blacklist" in your kernel parameters? |

Have you tried "module_blacklist" in your kernel parameters?I have done that now. Thanks. I haven't tried a reboot to check it yet. I wonder if it would be worth putting out a push notification on BOINC aimed at Linux users as I can see quite a few work units there are at least one or two failures because of VBox not starting just on work units where I have had tasks from. I know my way around a terminal to some extent but there will be a lot out there who don't. |
