#10975 closed defect (wontfix)

document which information from the host are visible to VMs

Reported by: Tsso Owned by:
Component: documentation Version: VirtualBox 4.2.0
Keywords: Cc:
Guest type: all Host type: all


Please make one section with all information from the host, which are visible to the VM. Information like hardware serials, battery information, cpu features, cpu mhz, etc.

Here are two examples, what I mean...

acpi -V
Battery 0: Full, 100%
Battery 0: design capacity .....
Adapter 0: on-line
Cooling 0: Processor 0 of 0
cat /proc/cpuinfo
although Synthetic CPU hides a bit,
mhz frequency is still visible

Those are just two examples, where I am aware about it.

It would be nice, if we had a list with all things, which are visible to the VM.

Such a list will be always incomplete and actually most information is NOT passed to the guest as the guest runs on emulated hardware. All devices are emulated, even the CPU. The CPUID information is passed to the guest because certain guests require it. For example, certain Windows versions will not work with the synthetic CPU -- that's also the reason why we didn't follow the approach of synthetic CPU information.
