[vbox-dev] getStatistic method issues

Sander, yes i know, as i mentioned, now i'm trying to get it working
under WinXP as guest OS with Guest Additions installed.

Klaus,
how can i make statistics to get updated by the Guest Additions? I
already set the GuestStatisticsUpdateInterval to 1 seconds, but still
have no success.

By the way, when i try to receive my VM statistics using "VBoxManage showvminfo
winvm2 --machinereadable" and "VBoxManage showvminfo winvm2
--statistics" command, i don't get anything useful related to
statistics except "StatGuestSample=0"

I do receive some general info like vmname, ostype and so on, but i
don't get anything statistic's-related [nothing of GuestStatisticType
SDK's list (MemoryLoad, PhysMemTotal, PhysMemAvailable and so on)]
except "StatGuestSample=0" (or string "Guest statistics for sample 0:"
in --statistics case) while i guess i should...

I'm trying to get it working on WinXP as host + WinXP as guest. Vb is
latest (3.1.4), GA - ver.1.4
Vbox.log has been attached.
