| #1294 | fixed | VirtualBox.exe pegs CPU when guest idle | ||
| Description |
A Windows XP Pro SP2 guest running on a Windows XP Pro SP2 host causes VirtualBox.exe on the host to consume 90% of the CPU even though the guest is idle and its task manager shows CPU usage 1 or 2%. Process Explorer from Sysinternals shows that the call stack of the offending thread in VirtualBox.exe is usually one of the following: ntkrnlpa.exe+0x6dbeb ntkrnlpa.exe+0xe807c ntkrnlpa.exe+0x6986c ntdll.dllKiFastSystemCallRet VBoxRT.dll!RTSemEventWaitNoResume+0x1a VBoxRT.dll!RTSemEventWait+0x39 VBoxVMM.dll!MMR3Term+0x86b VBoxVMM.dll!VMR3WaitHalted+0xea VBoxVMM.dll!EMR3ExecuteVM+0x248 VBoxVMM.dll!VMR3Wait+0x2d9 VBoxRT.dll!RTThreadGetType+0x1ab VBoxRT.dll!RTSystemProcessorGetActiveMask+0xfd MSVCR71.dll!endthreadex+0xa0 kernel32.dll!GetModuleFileNameA+0x1b4 ntkrnlpa.exe+0x6dbeb ntkrnlpa.exe+0x2b462 hal.dll+0x2ef2 VBoxVMM.dll+0x6a0fd VBoxVMM.dll!TMTimerPoll+0x1b1 VBoxVMM.dll!MMR3Term+0x7a6 VBoxVMM.dll!VMR3WaitHalted+0xea VBoxVMM.dll!EMR3ExecuteVM+0x248 VBoxVMM.dll!VMR3Wait+0x2d9 VBoxRT.dll!RTThreadGetType+0x1ab VBoxRT.dll!RTSystemProcessorGetActiveMask+0xfd MSVCR71.dll!endthreadex+0xa0 kernel32.dll!GetModuleFileNameA+0x1b4 ntkrnlpa.exe+0x6dbeb ntkrnlpa.exe+0x2b462 hal.dll+0x2ef2 VBoxVMM.dll!TMTimerGetMilli+0xf1 VBoxVMM.dll!TMTimerGetMilli+0x498 VBoxVMM.dll!TMVirtualGet+0xe VBoxVMM.dll!TMTimerPoll+0x21 VBoxVMM.dll!MMR3Term+0x7a6 VBoxVMM.dll!VMR3WaitHalted+0xea VBoxVMM.dll!EMR3ExecuteVM+0x248 VBoxVMM.dll!VMR3Wait+0x2d9 VBoxRT.dll!RTThreadGetType+0x1ab VBoxRT.dll!RTSystemProcessorGetActiveMask+0xfd MSVCR71.dll!endthreadex+0xa0 kernel32.dll!GetModuleFileNameA+0x1b4 |

| #1295 | fixed | Blue screen of death when disconnecting usb device in windows => Fixed in 1.6.4 | ||
| Description |
I attach an USB device, I use it and all is perfect. But, when I detach the USB device, either pulling the plugg or disconnect it in virtualbox I instantly get BSOD. I use Ubuntu Gutsy AMD64 as host, the USB device is a NI USB-6212. The guest os is Windows XP Pro SP2. |

| #1296 | fixed | Key Repeat breaks application event handlers -> fixed in SVN | ||
| Description |
Currently, VirtualBox apparently emulates key repeat events by repeatedly sending keyup and keydown events to the guest operating system, as if a user had really pressed keys that fast. This is problematic for writing applications that require keyboard input, such as games or other interactive application software, since it is impossible to distinguish an actual key event from a repeated key event. For example, in Internet Explorer and Firefox under Windows, key repeat usually triggers both the JavaScript keydown and keypress events, but not keyup. This way, it is relatively easy to filter out keydown events, since they are not followed by a keyup. However, under Virtualbox, key repeat triggers keypress, keydown AND keyup events. To immediately witness the effect, please try keyboard scrolling Google Maps with Firefox or IE in a Windows guest and a Linux host. You can also try the attached HTML file which contains reproduction code. Thank you for the wonderful VirtualBox software, and I hope I can make it better this way! Carlo |
