Guests fail soon after boot in exactly the same way, see log below when Pioneer DVD-RW is shared with "Passthrough" option. This worked few months ago, but I can't tell which version was vbox it when it worked. 9.1-STABLE amd64 Below is the end of the log with assert and few lines before that having some error (VERR_NOT_IMPLEMENTED) that may or may not be related.
