Hi, a downgrade to 6.1.40 solved the Windows 11 issue. Probably this https://pastebin.com/sKzMmun4]virtualbox-epoch1-6-1-40.sh clean chroot Arch Linux build script is useful for somebody else.
The guest additions packages is available by https://aur.archlinux.org/packages/downgrade]aur/downgrade and the extension pack by a download from virtualbox.org. # The extension pack, $ wget https://download.virtualbox.org/virtualbox/6.1.40/Oracle_VM_VirtualBox_Extension_Pack-6.1.40.vbox-extpack # guest additions $ sudo downgrade virtualbox-guest-iso Regards, Ralf
