VMMDevInterface.cpp@ 32876

Last change on this file since 32876 was 32851, checked in by vboxsync, 14 years ago
Main: defer creation of the VMMDev instance in Console to Console::powerUpThread so that the VMMDev with the HGCM thread only gets created for session/console pairs any more which actually power up a VM; this avoids creating dozens of HGCM threads for every single session even if it never starts a VM; some more Console code cleanup while we're at it
