#10636 duplicate gnome-screenshot and Vitualbox RDP doesn't work when Ubuntu 12.04 is running in 3D mode sx270169
Description

When running an Ubuntu 12.04 Desktop i386 version in Unity-3D mode (Virtual Machine 3D accelaration is enabled) everything works fine, but screen-shot and VM-RDP-Server is not working. When executing a gnome-screenshot there appears for one second an empty screen, and only this empty screen is saved in the screen-shot file. On RDP-client also only the empty screen is visible. If 3D acceleration is disabled, everything works fine, but Ubuntu switches into Unity 2D mode, which is very slow.

#10741 fixed OSX host crasher repro swork
Description

I have a simple-case repro for a host crash problem possibly related to several open or "closed - works for me" bug records here. It's quite consistent on my host (MacBookPro6,1, 8GB RAM). The VM config simplifications described below don't seem to be necessary but might help rule out culprits.

  1. Create two VMs, all defaults. Simplify the situation by eliminating disks (no devices attached to default IDE bus), disable audio, disable network cards.
  1. Run a shell-script loop starting both VMs then stopping both VMs. ("for i in 1 2 3 4 5 6 7 8 9 ; vboxmanage startvm empty1 ; vboxmanage startvm empty2 ; vboxmanage controlvm empty1 poweroff ; vboxmanage controlvm empty2 poweroff ; done")
  1. See host crash after a few cycles.

Notes:

  1. This is not a realistic use case, but I hit this (or a similar-symptom) crasher in actual use with two Ubuntu guests, with a script automatically stopping them at about the same time (one shell process issues "vboxmanage controlvm name poweroff" for both VMs in succession). I marked this "critical," hope you agree.
  1. Crash does not reproduce here if the IDE bus itself is removed from both VMs; could be the bus is implicated or just that the timing changes.
  1. Host OS is OSX 10.7.3

I'll attach a system crash report.

#8347 obsolete IRQL_LESS_OR_NOT_EQUAL BSOD Windows Guest/Ubuntu Host swoogan
Description

I'm using VirtualBox 4.0.2 w/ Extension Pack on Kubuntu 10.10 64bit. I have installed both Windows 7 64-bit and Windows 2008 R2 64-bit. Both BSOD with the IRQL_LESS_OR_NOT_EQUAL error when I log in for the first time after installing. Again, these are fresh installs after upgrading from VirtualBox 3.2. No guest additions as I cannot log in.

I also have a Windows 7 64-bit Guest that I installed with VirtualBox 3.2 w/ guest (3.2.12) additions. This guest runs fine in VirtualBox 4.0.2.
