Running with experimental Direct3d WDDM driver enabled. Reliably crashes when performing extensive I/O (some combination of network and disk). In the the case of attached vbox.log, I was simply cloning a mercurial respository from an HTTPS network location to a drive mapped to a VBox Shared Folder location on the host file system. Turned off the 3D Enabled option in the VM Display settings of the VBoxManager GUI, and system appears to be stable after performing the same operation." defect closed WDDM VirtualBox 4.1.10 duplicate Windows Windows
