I don't get this command (in https://forums.virtualbox.org/viewtopic.php?f=9&t=44566#p207673):

VBoxManage controlvm [vbox-name] keyboardputscancode 1d 38 54 [request type press/release] d4 b8 9d

What exactly should I type?

see http://www.halfdog.net/Misc/TipsAndTricks/VirtualBox.html (below "Running, Debugging")

Alt+SysRq+B is sent by providing 30 b0 as 'request type':

VBoxManage controlvm [vbox-name] keyboardputscancode 1d 38 54 30 b0 d4 b8 9d

[vbox-name] is the identifier (name, uuid) for the guest system that you want to manage.

Can you help with this problem?
