#11543 obsolete 3D Acceleration Fails with Compiz guest Matteus Blanc
Description

Overview:With 3D acceleration checked in virtualbox, compiz does not run properly in an arch Linux guest with XFCE Desktop Manager. This has been checked on all 4.x versions of VirtualBox.

Symptoms: With indirect rendering and loose binding the cube functions with both the keyboard and mouse but it is not possible to interact with the desktop e.g. clicking on icons won't launch any apps. If you attempt to move a window then there is no response until you invoke the cube. So basically the desktop is only redrawn with you do something with the cube.

Without indirect rendering you just get a black screen. If you do this from a root desktop then moving the mouse does reveal the desktop below the black screen but the cube is unusable (very laggy response, lots of tearing etc). The same thing in a non root desktop just presents a black screen.

This is not affected by changing out of full screen in the vm.

#1281 duplicate No serial port on Windows 2000 guest machine Matthai
Description

I am using the latest version (1.5.6) of Vbox on Ubuntu. I have Win 2000 guest virtual machine. I have enabled one serial port (COM1) - port mode is Host device, port path is /dev/ttyS0.

However, in Win2000 I can't see any COM port. I got an error at shutdown:

Ioctl failed for serial host device '/dev/ttyS0' (VERR_INVALID_POINTER). The device will not work properly.

Error ID: DrvHostSerialFail Severity: Warning

In VBox.log there are several lines with this:

00:05:36.795 ERROR [COM]: aRC=0x80070005 aIID={fd443ec1-0006-4f5b-9282-d72760a66916} aComponent={Mouse} aText={The console is not powered up} aPreserve=false 00:05:36.805 ERROR [COM]: aRC=0x80070005 aIID={fd443ec1-0006-4f5b-9282-d72760a66916} aComponent={Mouse} aText={The console is not powered up} aPreserve=false 00:05:36.815 ERROR [COM]: aRC=0x80070005 aIID={fd443ec1-0006-4f5b-9282-d72760a66916} aComponent={Mouse} aText={The console is not powered up} aPreserve=false 00:05:36.825 ERROR [COM]: aRC=0x80070005 aIID={fd443ec1-0006-4f5b-9282-d72760a66916} aComponent={Mouse} aText={The console is not powered up} aPreserve=false 00:05:36.836 ERROR [COM]: aRC=0x80070005 aIID={fd443ec1-0006-4f5b-9282-d72760a66916} aComponent={Mouse} aText={The console is not powered up} aPreserve=false 00:05:36.846 ERROR [COM]: aRC=0x80070005 aIID={fd443ec1-0006-4f5b-9282-d72760a66916} aComponent={Mouse} aText={The console is not powered up} aPreserve=false 00:05:36.856 ERROR [COM]: aRC=0x80070005 aIID={fd443ec1-0006-4f5b-9282-d72760a66916} aComponent={Mouse} aText={The console is not powered up} aPreserve=false

And machine does not shut down normally, but it is aborted. Any idea?

#11178 fixed Network Connection leak on Linux Host Kernel 3.2+ Matthew Jurgens
Description

Base system working ok: Virtual Box 4.1.8 with kernel-PAE-3.2.3-2.fc16.i686 or Fedora 16 Kernel 3.4.11-1.fc16.i686.PAE Running a single virtual machine guest Windows XP SP3 with 1 CPU and 1200MB RAM, 1 bridged ethernet adapter.

Upgraded to Virtual Box 4.2.0. After several days the number of network connections as reported by conntrack -S continually increased to the maximum limit of the machine (65536). Normally the host machine would have a stable "conntrack -S" count of somewhere around 500-600 connections, even after running for months.

Tried combinations of Virtual Box 4.2.0, 4.2.2 and 4.2.4 with kernel-PAE-3.2.3-2.fc16.i686, kernel-PAE-3.4.11-1.fc16.i686 and kernel-PAE-3.6.2-1.fc16.i686. Any combination with 4.2.x resulted in the network connection leak.
