Hi, the execution of a Windows 11 (64-bit) guest works, with the exception that the shutdown does not end, but this was already a problem under 7.0.20-1, which you can live with. Under 7.0.20-1, a Windows 10 (64-bit) guest, including the shutdown, worked perfectly smoothly. Unfortunately, the Windows 10 startup freezes under 7.1.0-1. Its log ends with "00:01:40.881013 EHCI: USB Suspended". By the manager settings I changed a few settings, to use mainly the same settings for the Windows 10 guest, that are used by the Windows 11 guest. In addition I migrated from USB 2.0 to USB 1.1 for the Windows 10 guest. Now USB is operational and I couldn't see any useful information by the log file. I'm in a hurry as I have to go to work and will read the logs again later at my leisure. Has anyone had similar experiences? FWIW pacman.log mentions an issue: [2024-09-13T05:02:52+0200] [ALPM] upgraded virtualbox (7.0.20-1 -> 7.1.0-1) [2024-09-13T05:02:52+0200] [ALPM-SCRIPTLET] VBoxManage: error: Failed to create the VirtualBox object!
