The VT-x/AMD-V Exclusive setting allows VirtualBox to exclusive use
hardware virtualization and not share it with other parallel hypervisors
in the system (i.e. expected to run simultaneously with VirtualBox).
Exclusive is the default for Linux and Solaris hosts (has always been
this way). On Windows and OS X hosts, VirtualBox, by default, is
configured such that it can be run in parallel with other hypervisors
*provided* the other hypervisor also shares the hardware virtualization
resource in a compatible manner.

Ram.

HWVirtExProperty... I don't about it. I'm not aware of shared VT-x, so
it seems to be always exclusive. Basically you can't run MS VirtualPC
and VBox sametime on Windows hosts or KVM and VBox on Linux hosts.
