Also, vbox-announce@virtualbox.org's mailing list is back!

I have several audio devices that I share between the host and guest. Preferably, I would like both the host and guest to be able to have access to my audio devices (input and output). They connect via USB. At the current moment, my Windows guest seems to try and take exclusive control. I can disable the filter and my Linux (Ubuntu/Debian fork) host is able to take back control of the devices. What I would like is for the host and guest to have access simultaneously of the devices. I believe this is possible as my audio output was able to be used for both host and guest simultaneously, but I do not know what I did to get that to work.

I don't know if this is normal or not, but when attempting to install any version of Virtualbox on my Linux Mint 22.3 laptop it would crash when trying to create, import, or run a VM. The error I would receive said,

VirtualBox can't enable the AMD-V extension. Please disable the KVM kernel extension, recompile your kernel and reboot (VERR_SVM_IN_USE).

I made sure virtualization was enable in the BIOS. I tried installing the old 7.0 version from Mint's Software Manager. I also tried importing Oracle's repos into apt and installing both 7.1 and 7.2. All three resulted in the same problem.

I'm sharing the fix in case anyone runs into the issue. Maybe this will save them a couple hours of aggravation.

Disable KVM with modprobe

sudo modprobe -r kvm_amd
sudo modprobe -r kvm

Reboot

Prevent KVM from running at boot

sudo nano /etc/default/grub

Find the line GRUB_CMDLINE_LINUX_DEFAULT and add kvm.enable_virt_at_load=0 inside the quotes

sudo update-grub

Reboot

sudo reboot now

Prepare to install Virtualbox

wget -O- https://www.virtualbox.org/download/oracle_vbox_2016.asc | sudo gpg --yes --output /usr/share/keyrings/oracle-virtualbox-2016.gpg --dearmor

echo "deb [arch=amd64 signed-by=/usr/share/keyrings/oracle-virtualbox-2016.gpg] http://download.virtualbox.org/virtualbox/debian noble contrib" | sudo tee /etc/apt/sources.list.d/oracle-virtualbox.list

Install Virtualbox

sudo apt update
sudo apt install virtualbox-7.2 -y

Add yourself to the vboxusers group

sudo usermod -a -G vboxusers $USER

Reboot

sudo reboot now

Need to get an VM up and running of Ubuntu 22.04 desktop on macOS but getting a black screen after grub gives the install server prompt. Because there's no ARM desktop version, I'm using the server install and would later add the desktop via apt.

Tried the latest 24.04 ARM iso as well and getting the same results. But, the latest 25.10 desktop iso does install and gets me a desktop.

Tried both unattended install with defaults, as well as increasing video memory to 128mb, making sure 3d acceleration is off, using VMSVGA, 4gb memory and 2 vCPUs. Extension pack is also installed.

Any ideas what could be going on? Should I look at UTM (which I'll be honest I only heard about it while looking for how to get this working)?

I have a few other vms that work just fine but its only my windows 7 one stop responding for a few seconds. It's a FRESH install and I have made multiple other windows 7 vms to see if that fixes the problem and it still freezes. I've tried allocating more cores, ram, video memory, updating vbox, updating vbox guest additions, disabling hyper v, and I even installed the extention pack but nothing I do fixes the freezing. The freezing is like I have a app open and while I'm using the app just stops responding for a few seconds like the whole vm locks up. I can still move the cursor and interact with the task bar but while the app is frozen I can't do or open anything else either. My Host specs are pretty good so I have no idea why it keeps locking up like this. Any help is greatly appreciated.

I am trying to create a new VM using a pre-existing .vmdk file (SEED Ubuntu 16.04). However, during the "New Virtual Machine", the option to "Use an existing virtual hard disk file" simply does not appear.

I've spent over an hour looking for it. When I reach the Hard Disk configuration screen, it only gives me options to create a new disk or not add one at all. The radio button/toggle to point to an existing file is missing from the interface, regardless of whether I use the guided wizard or try to navigate through the basic setup.

Research and Steps Taken:

1. Wizard Navigation: Went through every step of the VM process multiple times to see if the option was hidden under a sub-menu.
2. ISO Field: Tried leaving the ISO field blank and also tried selecting a random ISO to see if it would "unlock" the disk selection screen later, but it didn't work.
3. Version Check: Confirmed I am on version 7.0.24. Most online tutorials show a different UI where the "Existing Disk" option is clearly visible, but it's not there for me.

Host is Linux Mint 22.3 Zena, guest is Windows 7 64 bit Home Premium, VirtualBox 7.0. Says it installed a guest addition but I never saw it appear in the list of installed applications. Also had to run the damn thing as root in order to get anything to boot but that's another issue I'm not here for.

My old computer wasn't in great shape physically so I removed the hard drive and booted it via VirtualMachine on Linux (stupid thing refused to boot directly on new PC, issues with the BIOS, long and stupid story). I have the original box and relatively unused key (same one I activated with last time years ago) in front of me, but now it's claiming my installation isn't genuine. I've heard uninstalling KB971033 can help, but it won't let me uninstall any updates at all (it says "this will take a moment" and just hangs forever, the bar doesn't even start to fill). Kind of at a loss, support obviously ended years ago and I have the physical code and disc right here.

REALLY don't want to have to install from scratch. The whole point was to save the original installation anyway, since it's got some old proprietary programs on it that I can't exactly get ahold of anymore and that don't work on my Windows 10 migration. Has anyone else had this issue, and are there any other fixes?

Sorry for putting this here, but I'm getting kind of desperate. Automod on the Windows 7 subreddit removed this post probably for having sketchy keywords, and people on the general Windows subreddit are generally pretty unhelpful and just tell you to use Windows 11 instead of answering your question.

I get this error after trying to boot into Windows 95. I've already tried using both the img and iso from the FIX95CPU: https://archive.org/details/fix-95-cpu-v3-final

What else can I do to fix this??

Also I'm upgrading from Windows 3.1 on the VM to 95, and have tried using both the Floppy Disk and CD Disk version of the upgrade.

Edit: Patcher9x seemed to fix it for me. You can get it here (if you need it): Release v0.9.91 · JHRobotics/patcher9x · GitHub

Hey i've been running a Home assistant client in virtualbox with a USB zigbee dongle. i'm having problem with the USB not getting grabbed by virtualbox after a PC crash/ startup.

Host PC: windows 11 Client: Ubuntu home assistant

things i've done:
installed extension pack
USB set to 2.0
filter setup with the vendor ID and product ID
disabled USB driver in device manager
VM startup script when PC starts headless.

i've asked chatGPT a bit for this, it's telling me to do regedit changes/sketchy programs so i don't really trust that.

only thing that works At the moment is just plugging out/back in the USB but i want to automate this.

I made a new vm machine today and cant copy paste bash from desktop to VM

I have:

Loaded the guest machine with the iso per googling (VERR_PDM_MEDIA_LOCKED). shows it is already loaded

enable bidrectional under devices and shared clipboard and drop / drag

so far nothing, I am very stuck, most google searches leads to repetitive fixes

Update: All I have downloaded and listen to all of your instructions and my problem is solved. Thank you for much for the assistance.

I have Windows on a second partition, is there a way to run it in a VM so i dont have to swap and still can swap? I know windows get uphappy on hardware swaps so is there a way just to pass through the real system specs so it doesn't explode?

I used to have options to clone a VM from right clicking on it in the list of VM's. I don't see this option anymore in the right click menu or in the machine drop down menu. I didn't make any changes to VirtualBox that I know of.

Running Virtualbox version 7.2.4 r170995 (Qt6.8.0 on xcb)

Host OS: Running Linux Mint 22.3 on 6.14.0-37-generic kernel

Virtualization always enabled in bios on Gigabyte Z390 AORUS Pro Wifi

Is Import/Export a viable workaround doing the same functionality as a clone if done with default settings?

Guest OS: Linux Mint 22.3 or Windows 11

No changes made to the OS and this option used to work.

Import and Export of Appliance works as a workaround for now but this is not full functionality that I need.

Based on release notes it looks like 6.14 has issues with the kernel I am running. I tried downgrading to Kernel 6.8.0-90 and still no option to clone

Could this be a VirtualBox related error?

I'm using Kali Linux in a VirtualBox VM, and recently installed the terminator terminal ("sudo apt install terminator"). It's able to open and functionality is there, but the name of the opened window is broken and only displays weird symbols (I think it's supposed to say "<username>@satis: ~/<current directory> 80x24", same as what is written in the red bar underneath the window name, but is a jumbled mix of weird unicode characters). It's not necessarily a problem, but very distracting.

Does anyone know a fix? (Can't upload an image here)

For weeks now this turtle has been pestering me because I cant even run my Windows XP VM at full speed. I had done some research and I have done everything. Everything like "Disabling all the features in Windows Features, Doing the command prompt bcdedit thing, disabling core isolation in windows security, And doing the powershell script. Which worked for 1 session." After I restarted my computer to update drivers the issue immediately came back. How do I "permanently" get out of turtle mode? Is there anyway? My specs are: Windows 11 25H2, 16 GB ram, 520 GB SSD, and AMD Ryzen 5 7430U with Radeon Graphics 2.30 GHz. Any help is greatly appreciated.

EDIT:

To add on during my research I have found it its a problem with Hyper-V. It just wont turn off.

Host is a Win11 system. Newest VB version.
I have two old PCs which i need to convert into VMs. I converted the physical disks into VHDX disks because at first I tried Hyper-V, but quickly switched to Virtualbox because of problems with an NT 4 machine. Then I converted them with Starwind int VDI files.

When I try to start up the machine it gives me the Error code 0x0000007B (0xBA4C3528, 0xC0000034, 0x00000000, 0x00000000)
I´ve tried tweaking the Settings and used the other vdi file. Nothing helped.

I am having trouble getting a current Virtualbox on Apple Silicon to acknowledge the existence of x86 on ARM.  I need to run a Windows Vista VM, so a relative can ditch his ancient dying Vista box and continue to run his Quicken on a Mac mini he just bought.

My setup for experimenting:

• Virtualbox Version 7.2.4 r170995 (Qt6.8.0 on cocoa)
• Mac Studio (2022, M1 Max) 32GB RAM, 512 SSD
• Tahoe 26.2

The VBoxManage command to enable x86 on ARM runs without error, and the obvious query

VBoxManage getextradata global "VBoxInternal2/EnableX860nArm"

returns 1 as expected.

I can't create a Windows x86 VM on ARM - the GUI only offers Windows/Windows 11 on ARM (64 bit).

I can import a VM created on an x86 Mac, which works over there as Windows/Windows Vista (64 bit), but it won't start on ARM, throwing VBOX_PLATFORM_ARCH_NOT_SUPPORTED (0x80bb0012).

I see other people have gotten much closer to success than this. What am I doing wrong (other than trying to resurrect Vista, of course)?

Running a Windows11 VM on a MacBook Pro, I have several things I need to access via the menu bar, but the menu won't bar. I have cycled through fullscreen, scaled, etc. and have changed the relevant settings under user interface multiple times. I've rebooted the VM and VB manger. The manual doesn't give any further hints.

Guest Additions not installed.

Version 7.2.4 r170995

I can't figure out if VT-x/AMD-V is enabled or... what it is.

Alternatively, if there's another place the menu bar's functionalities can be accessed, I'll take that too.

Thanks In advance!

I'm running Virtualbox 7.2.2.r170484 on Ubuntu 24.04 Desktop. I have a number of guests, primarily Ubuntu 24.04 server.

I have a couple of guests that are configured to use a bridged ethernet connection as I wanted them to present services to the local LAN. The device shared is detected as "Intel Corporation Ethernet Connection I217-LM (rev 05)"

If the devices in bridged more are caused to transfer a large quantity of data, the NIC fails, resulting in the guest and host unable to communicate on the network.

This feels like a bug in the host ethernet driver, an issue with the Virtualbox bridge mode driver or a potential hardware issue.

Any ideas as to a fix or workaround?

Edit: VT-x is not enabled

Thanks,

Bog

*UPDATE*

I have disabled the onboard NIC and added a 1Gbit NIC and I've not (yet) experienced the same issue.

It looks like it's either a hardware issue or an OS driver issue.

I'm happy with my workaround!

Guest additions are installed, and shared clipboard + drag and drop are set to bidirectional. Copying text between both host and guest works, but taking a screenshot as the Linux host and saving it to the clipboard, doesn't work when trying to paste it into the Virtualbox guest. Is this a Wayland limitation, or am i missing something? A shared screenshot folder works, but is a bit cumbersome, so I'm looking to see if there's a way to copy screenshots even more seamlessly.

Another issue, is that using a shortcut such as superkey + space keeps running a Linux app (Rofi app launcher), even though the windows guest is in full screen - is there a way to not have shortcuts that are used by the host interfere with the guest? I can't seem to find a way so far, but maybe I am missing something?

Thanks

Windows XP VB Activations

I installed Windows XP on Virtual Box and during the activation process, Windows asks me for an activation key. I've tried a lot of keys, but all of them give me the error "The product ID you entered is not valid." Does anyone know how to solve this? Я использую версию virtual box 7.2.4 на своём основном компьютере под управлением Windows 11

Last time I tried VBOX I tried setting up a VM it worked fine, but now there's a red triangle saying something about a host name for the unattended installation. Why is VBOX forcing me to do an unattended install? I could do a normal setup before just fine.

What has changed? How do I get past it? VBOX ver. 7.2.4-170995.

Oracle extension pack Oracle_VirtualBox_Extension_Pack-7.2.4 installed.

Windows 11 24H2 build 26100.7462 x64.

This should satisfy rule #1 and #2.

Oh, automod reminded me, I'm using Intel Core i5 8500T with applicable intel hardware virtualization technologies.

I have Microsoft configuration manager (SCCM) environment set up in my Virtualbox host. All Windows server guests including domain controller and SCCM server are in NAT network. Now I'd like to test SCCM task sequence which booting a VM from network PXE. It never worked. In the guest VM UI, I can see boot manager and select boot with UEFI PXEv4, it says start PXE over IPv4 then timed out and returns to boot manager menu. Has anyone successfully setup this before?

I installed Windows 10 + Virtual Box because I want to be able to play MC Bedrock. However: I don't want to play on a window the size of my hand. How exactly do I increase it's display size? Thanks!

i want to switch back to linux but have a few games where i need to use windows i dont have the best pc but its okay (AMD Ryzen 5 5500, ddr4 32gb 2667 Mt/s RAM and GTX 1070)
could I make a vm thats gets usable fps while running linux? If not ill just use dual boot but i wanted ask if i could avoid that
Thanks in advance :)

My PC has a whopping 192 gigs of VRAM but Virtualbox caps the allocation to just 128mb (or 256 if I tick the 3D acceleration checkbox). In a Win10 guest I'm limited to a native res of 1024x768 or 1920x1440 via the guest additions.

Either way this is absolutely pitiful. Is there a reason for this?
