[POSSIBLY SOLVED THE PROBLEM] It appears that something similar was going on here. I'm actually using Kubuntu, which I tend day-to-day to think of as Ubuntu but it isn't. KDE has pulseaudio as the default sound environment. As the DSP processor is recognized as a sound device pulseaudio was attachin...

Note - as per some debug instructions here: https://forums.virtualbox.org/viewtopic.php?f=35&t=82639 1) As far as I can tell all power management is disabled in the VM and 2) I installed USBDeview. It shows the DSP processor as connected through USB and when the application loses contact with th...

My desktop machine is Ubuntu 22.04 LTS, fully updated, but also dual-boots into Win10 which works fine. Running in Ubuntu I have a Win10 Virtualbox VM which I have run for a number of years. It is fully updated as per Microsoft's update service and in general it seems to running perfectly fine. I ha...

Thanks for the clarification. I have not asked the maintainer as of yet as I thought it was part of the main distribution. I will do that now. I've used Virtualbox for a long time but am having problems right now with one Windows program. I have no reason to believe that the problem is really caused...

Hi, I am looking for documentation on the purpose and proper use of the xf86-video-virtualbox package. If I am running only Windows guests on a Linux host is it a requirement to have this driver in my host's xorg.conf file or is it just used in a Linux guest? I looked in the 5.1.24 User Manual onlin...

So after a few months of this problem, and sadly the problem began to appear on other apps as well in multiple Win 7 VMs, I found an apparent solution. If anyone ever should ever find this post they can try these changes in Windows 7 as they worked for me: 1. Right click on Computer and left click o...

Hi, This is a fairly weird little problem that I've had for a year or so. It impacts only one application that I know of. The system is Gentoo, mostly stable, kernel is 4.4.26-gentoo, NVidia drivers, Virtualbox-4.3.38_Gentoo r106717 which is the most recent stable version of Virtualbox. The applicat...

OK, hopefully everything is in the attached zip. These files were taken with the machine running live. If that's a problem I can shut machines down later today. The two working VMs are Builder & Win7-DualMonitor. The failing VM is TradeStation Stable. NOTE: The _ONLY_ way I mean fail WRT to thes...

BTW - In the *.vbox files all three VMs have the same code:

<Clipboard mode="Bidirectional"/>
<DragAndDrop mode="Disabled"/>

This system runs Gentoo Linux and KDE as a desktop manager. I've run Virtualbox for quite awhile with 2 VMs. Bidirectional copy/paste works fine between KDE and the older 2 VMs. Linux-> Windows or Windows-> Linux. This allows me to copy/paste between the older 2 VMs just fine. I built a 3rd VM for s...

OK, so looking around more I ran across this link

http://www.virtualbox.org/manual/ch09.h ... assthrough

which suggests it's possible, at least with simple cards and specific hardware setup issues like interrupts not shared. This is good. At least I've got a starting point.

Is it possible to dedicate a hardware VGA that is physically in a Linux system but is unused by X to be directly available to a Windows 7 guest running in that system? I.e.- the monitor attached to that VGA would be blank until the guest was running and then show up when the guest is started? If the...

Things are still good for me but unfortunately there are other Gentoo users reporting problems in the Gentoo bug system with 4.3.4 so this may not be totally solved yet.

Well, good news so far. I'm currently running virtualbox-4.3.4 under gentoo-sources-3.10.21 with the following PREEMPT settings: mark@c2RAID6 ~ $ zcat /proc/config.gz | grep PREEMPT CONFIG_TREE_PREEMPT_RCU=y CONFIG_PREEMPT_RCU=y CONFIG_PREEMPT_NOTIFIERS=y # CONFIG_PREEMPT_NONE is not set # CONFIG_PR...

Namely setting only the R...
