virtualbox.org

Hello,

I'm using the current realease of Oracle VirtualBox Software: 4.3.14.
Oracle VM VirtualBox
Oracle VM VirtualBox Extension Pack

Guest OS : Windows 2012 Server Standard Edition (W2k12 SE) fresh installation

Issue
=====
A few seconds after logging on to the guest OS the VM just freezes (hangs) without an error message.
This issue occurs constantly after I have installed the virtualbox guest additions.

Additional information
=====================
This W2k12 SE guest VM runs fine if I start it in Safe Mode with networking

Attached the appropriate VBox.log

Would appreciate any help.

Best Regards
Alex

I found a couple of maybe interesting titbit in your logs (which may very well be totally irrelevant):

00:00:06.301950 Audio: Trying driver 'dsound'.
00:00:06.404979 DSound: Could not initialize DirectSound
00:00:06.405080 Audio: Initialization of driver 'dsound' failed, trying 'dsound'.
00:00:06.405245 DSound: Could not initialize DirectSound
00:00:06.405276 Audio: Initialization of driver 'dsound' failed, trying 'null'.

00:00:52.008512 Guest Log: VBoxMP::VBoxMpCrCtlConInit: VBoxMpCrCtlConConnectHgcm failed with rc(0), 3D not supported!
00:00:52.008612 Guest Log: VBoxMP::DriverEntry: 3D is NOT supported by the host, falling back to display-only mode..

See if you change the sound options and/or disable 3D acceleration in the VM settings changes things. Just a shot in the dark...

Hi socratis,

The 3D option was (is) not active.
Disabled the sound device within the VM configuration, but the system still freezes...
