VirtualBox

source: vbox/trunk/src/VBox/Main/include/VirtualBoxImpl.h@ 30847

Last change on this file since 30847 was 30847, checked in by vboxsync, 15 years ago

Main/Machine+Performance+VirtualBox: move deleting the performance metrics registration of a VM out of SessionMachine::uninit, where it was a risk of hangs due to callbacks. Doing it a little later won't hurt anyone. Additionally also make sure the total VMM memory stats are zeroed when the last VM has disabled its collector.
