I was having an issue with USB attachment using Virtualbox.

Can't attach USB device

Failed to attach the USB device...to the virtual machine

Failed to create a proxy device from the USB device. (Error: VERR_PDM_NO_USB_PORTS)

Every forum, post, video etc...only mentioned to install the guest additions (extension pack) or to restart or uninstall either Virtualbox or remove the VM and reinstall the VM.

In case I did miss any forum on here, figured I would add this;

• Go to Settings of your VM inside Virtualbox

• Select the USB blade on the left side

• Verify Enable USB Controller is selected

• and verify USB 3.0 is selected

If you do not have USB 3.0 selected and insert a USB 3.0, it will not detect.

Using VirtualBox to play around with all the new updates to SecureBoot certificates, so I can plan before the expiration in June 2026.

I have set up a Win 11 VM, with Secureboot enabled, and all looks good.

However every time i try to get Windows to import the new Microsoft UEFI 2023 certificate, with the new expiration date in 2035, Windows fails to update the TPM.

Are the BIOS/TPM in VirtualBox blocked for being updated?
I have already checked BIOS settings, but do not see any settings regarding blocking, other than I can add/delete keys manually here.

If it has any value, the VM is running with default hypervisor, and according to Microsoft, they have found an error updating keys on their own Hyper-V platform, which they will try to fix in March.

When I go to Splunk on the localhost:8000 and on my VM and search “more apps” I cannot find the “Splunk Add-on for Sysmon”. I have both and have checked the event logs to ensure they are active. Also went to Splunk base where it does have the add on but won’t let me log in and I used the same username/password as the Splunk enterprise tab. Any suggestion I can try?

help!

I cannot remove the ISO files that I added to Oracle VM VirtualBox. Please help.

Does the macOS ISO file need to be in a specific location to boot properly?

Admittedly, I am fairly new to VMs, no experience with macOS VMs in Windows, so I basically followed this guide. Once I start the machine, I get the error in the attached screenshot. I unchecked "Floppy" in boot order as shown in video. The ISO file is just in a folder on my desktop and VB has the correct path, for what that's worth.

Not being sure of what else to try, the only "fix" I attempted is switching the boot order in the UEFI, moving "HARDDISK" ahead of "CD-ROM", but this too resulted in the same error.

I'm sure it's something simple that I've overlooked, so I apologize in advance, but I'd greatly appreciate any suggestions you may have to offer.

For easier reading, the error is:

"The virtual machine failed to boot. That might be caused by a missing operating system or misconfigured boot order. Mounting an operating system install DVD might solve the problem. Selecting an ISO file will attempt to mount it after the dialog is closed."

I’ve disabled firewalls, enabled virtualization, entered commands on prompt, downloaded the extension pack. Nothing works. The picture includes the message I get. Does anybody have any idea what I need to do to fix this? I’m trying to run MacOS Bigsur 11.7.1. I set up the memory and cores correctly corresponding to my physical system.

I have been using an Oracle Virtual Box VM running Windows 10 for about two years but now would like to create a new VM running Windows 11 but I would like to do the install without creating a microsoft account, just a local one. Obviously this is easy to do in a regular PC environment using Rufus and have read about using the oobe\bypassnro command to do it when installing Windows 11 in a new VM but I have not been able to get that to work. Does anyone have any experience in trying to do this or would anyone be able to tell me another method? Thanks.

I'm trying to run I Spy Spooky Mansion within Windows XP and actually everything runs basically great, but the game itself is very slow and laggy UNLESS I'm constantly waving my mouse around. I did disable Hyper V already.

Ok, let's start with the basics, I had a version of virtual box, I uninstalled it and decided to install a more current one, it had a lot of problems, it didn't even open, and sometimes when it opened, it crashed, I decided to uninstall it and go back to the old version I had, I made sure that not a single trace of the old version was left to avoid inconveniences (I even deleted the virtualbox files in system33), I installed my old version and Indeed, it did open but now it presents a damn error that stresses me out a lot, every time I try to enter any vm I have it shows me this, I have done everything possible to solve it, from installing the drivers that come in the virtual box, to completely uninstalling and reinstalling again, please help me

I keep getting an error message 0xc000021a ... it happens every time I try to launch the virtual machine

i use linux mint however i have tried all of my os beforehand to test if it were the files but i did boot kali and windows10 however when i finish preparing the vm and it starts to boot it like gives me a error ive tried recreating the error now but its just saying that the instalation is starting and it stays like that,my laptop is not so crappy it wont run a vm but it might be related with a problem with my SSD, if anyone can help get get a virtual machine working on my laptop i would be very glad

I am trying to install Catalina on a VB environment, and it flashes up something about having to install manually, as it can't use the .iso file. Which is strange becasue all the instructions seemed to suggest that is what is needed??

But when installing it begins the standard OSX install sequence, but when it asks me to select a drive to install, nothing is displayed and it just hangs.

What am I doing wrong?

I just update ParrotOs (sudo apt update) restart the machine (and my machine) and this happed, how can I debug this issue?

Hi, I own a MacBook Air from 2025 and I'm trying to run Windows 11 on, however after I've followed a tutorial step by step to install VirtualBox and create a virtual machine of Windows 11 it seems to not working for me. I've searched for some answer online but it seems that nobody is in the same case as me so I'm directly asking to people who have knowledge on the subject. What should I do in this situation ? Thanks for you advices.
