An additional bit of info … if I put the DVD in the drive and use the VBox passthrough driver I can install from the DVD. I do not have DVD drives on all the host systems though.

The error is VERR_NOT_SUPPORTED and my research has led me to the conclusion that the problem is that these are UDF format ISO’s (so that they may contain files larger than 2 GB). I also cannot mount the ISO under FBSD using mount_udf, so they are a newer version of UDF than mount_udf supports. I assume this is the crux of the issue VBox is having, the underlying OS does not have support for this version of the UDF spec.
