If you installed the extension pack manually, then go to the VirtualBox download page and find the VirtualBox Oracle VM VirtualBox Extension Pack there.ĭuring the installation of the new version, you will be prompted to uninstall the old version. To fix this problem, just install the version of the VirtualBox Extension Pack that matches the version of your VirtualBox. Or go straight to updating the extension pack, which will solve the indicated problem. To make sure that the reason is in the VirtualBox Extension Pack, you can disable the functions that the extension pack provides in the virtual machine settings (for example, rollback to USB 1.1 version) – after that the virtual machine should work without errors. VirtualBox Extension Pack is an extension that adds features such as support for USB 2.0 and USB 3.0 devices, VirtualBox RDP, disk encryption, NVMe and PXE boot for Intel cards. One possible reason is a mismatch between the versions of the VirtualBox Extension Pack and the installed version of VirtualBox.

The situation is complicated by the fact that instead of an exact indication of the problem, when trying to start the virtual machine, only a general message is displayed that the session was terminated, as well as an error number, which is common to a number of errors related to the inability to start the virtual machine session.

After updating VirtualBox, all virtual machines stopped working, regardless of the guest operating system and their settings.
