Comment 48 for bug 1487168

Regarding this update and the previous update referencing a Verbose VBox
Log.

Trying to find out what a Verbose Log is or how to activate Verbose
logging, I looked for Verbose in the user manual and got hits in Chapter 8
of
the User's manual. I see references to VBoxmanage command syntax. It is
not obvious that any of these commands turns on Verbose logging in general.
Are you expecting me to issue one or a series of these commands or is there
another location where a verbose log is kept other than what I supplied?
if you are unable to answer this question, I will have to work with the
VirtualBox Team.

Second item is the patch you referenced. The link supplied is to C source
code. I cannot find references on what to do in order to compile this code.
I did see that there was a process to create a Source Code Fork in order to
be able to compile the entire forked copy of the source.
Are you telling me to follow those steps and substitute this version of
that module and try testing again?

Another question is the observation made about Dell. I own a Dell Laptop
however the platform that runs my Virtual Box testing environments is a
self constructed machine based off of Intel DX79SI Motherbpard and a Intel
Xeon Processor. In other words there are No Dell Branded parts in this
machine. What does the reference to Dell mean?
