I would suggest you to read some papers about full virtualization

I am noticing 100% cpu utilization by VBox when I run
apps on guest, which when run on host, do not use more

Does you manager know you have this type of

No one is coercing YOU to respond to my emails.

For the sake of most of us who do not have the
time bandwidth, would you be kind enough to state
the location in the source code where guest
instructions are run natively on non-VT hardware?
It would be very helpful.

Definitely a problem that needs to be fixed.
