I am having a problem in Virtual Box. I can only create 32 bit VM's, I am running windows 10-64 bit so this should NOT be happening. And also whenever I run a new VM I get this.
Failed to open a session for the virtual machine kali.
VT-x is disabled in the BIOS for all CPU modes
(VERR_VMX_MSR_ALL_VMX_DISABLED).
Result Code: E_FAIL (0x80004005) Component: ConsoleWrap Interface:
IConsole {872da645-4a9b-1727-bee2-5585105b9eed}
But I know for a fact that I have Intel VT-d/x enabled. Any suggestions are helpful.
This error arises due to virtualisation is disabled by your operating system. So:
Go into the BIOS setup (by repeatedly pressing F10 or F2 or F9 depends upon your motherboard while your system is booting)
Click the Advance option.
Find virtualisation in the list.
Make sure it's enabled .
To save the changes you have done press F10.
Now probably you will not encounter the same problem in virtual box when you run it.

I built an operating system and it successfully booted with qemu. However when I try to boot in on VMWare, a triple fault occurs. I used a floppy to boot it in both cases. How can I find the error code of the triple fault from VMWare? I tried looking in the virtual machine logs but I couldn't find any more details.
As you know,qemu runs programs by its virtual cpu and full virtual hardware...
but vmware will use VT(virt-tech) to get better performance and all device is running on mix-virtual mode. so it will takes you more difficulty such as running status checking will be restrict ,random config address...or whatever things.they all make your kernel into fault
To find this problem.make lots of breakpoints before where will be problem(such as running level switching,write MSR regs,config ACPI..)and run,if it still running correctly,remove next breakpoint. do debug one by one
could you give me your repo address if possible then i will answer this question better(upload your logs is also can help me)
I have followed this tutorial for developing an operating system. I am using Windows 10 as my host sytem and used wsl for compiling. But my VM fails as soon as I enable interrupts.
This is the log file of the VM that is output, but I cannot understand it. I am pretty naive with VirtualBox. Can someone explain any possible error you see?
Here is the code of the Os. I just have changed the structure I believe. Rest code in execution point of view is same as shown in video series.
That is a lot of log to scroll through and it's hard to be sure on the face of it that just looking at that would be able to tell us what about your startup code (not visible to us as part of the question) would trigger it. However, I can speak to some general strategies about approaching a log file like this.
We can see some general state transitions in there. The log ends with:
00:00:15.712045 Changing the VM state from 'DESTROYING' to 'TERMINATED'
So I can go back through and look at where the first instance of DESTROYING showed up, which was:
00:00:15.698320 Changing the VM state from 'POWERING_OFF' to 'OFF'
00:00:15.701802 Changing the VM state from 'OFF' to 'DESTROYING'
Following the same process backwards to POWERING_OFF, I see:
00:00:08.577363 !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

That error line at the top of that block may point to something searchable that would turn up other instances of people having the same or a similar problem. If you scroll up a bit, you can also see that something VGA-related was happening right before the error, which may help narrow it down if it's directly related to the error, or may be another step to backtrack through on the way to the real issue.
I get the following error after upgrading via Migration Assistant my laptop from a 2-core to a 4-core processor:
cpum#1: X86_CPUID_FEATURE_ECX_MOVBE is not supported by the host but
has already exposed to the guest [ver=17 pass=final]
(VERR_SSM_LOAD_CPUID_MISMATCH).
How can i resolve the same?
The solution may be as simple as clicking the big yellow "Discard" button, which will delete the saved state (same as pulling the power cord).

For people working via a terminal.
The accepted answer correctly mentions to discard the current state of the VM. This basically means pull the power cord, so that the next time you start it, the machine reboots.
You can do this using
VBoxManage discardstate "your machine's name"
Click on the name of the virtual machine, right click on the menu and discard saved status
The Discard button worked for me. Thanks #Justin!
I've been chasing this exact error message off and on for months (fortunately my VM is not part of my daily work). The whole time I thought that it was an issue of being on a new CPU (based on CPUID_MISMATCH) so I was looking at how to move a VM from one CPU to another and how to change the expected CPUID. But everything I found in that searching required that you save and shut down properly on the original CPU, which I no longer have.
Simply "Discard"-ing the "Current State (changed)" version worked for me on all of my saved machines.
Whoda thunk that the fix for a virtual Windows machine was a hard reboot? Not like that works for hardware-based Windows boxes, right? ;-) I guess that's why they call rebooting "the Windows Panacea".
Thanks again.
Im trying very hard to like virtualbox, but so far I find it so much worse than vmplayer in so many ways. If it wouldnt take me hours to install everything back into vmplayer i would have moved back days ago
When I open my ubuntu vm my host OS's (windows 10) toolbar is still visible at the bottom of the screen, cutting off the actual virtualbox toolbar
Please help me
(edit) It is in fullscreen mode already, it just still shows the toolbar/taskbar from the host OS
Open Task Manager of Windows 10, Select "Windows Explorer" and Restart.
Reference Link
I had this same issue. The Windows 10 taskbar was still showing when I had VirtualBox in fullscreen mode, and what caused it for me was I had a program called Rufus (for creating bootable USBs) open and it was keeping the taskbar from hiding. Once I closed Rufus, everything worked as it should. So, maybe you had a program keeping focus on the taskbar, something that needed attention, and wouldn't let the taskbar hide.
I ran into the problem once. Not sure what had caused the that but I managed to find a solution by enabling "task bar" hiding option in host windows 10 machine.
Right Click on Task Bar -> Task Bar Setting -> Enable Task Bar hiding Option.
You are able to switch to fullscreen mode on the VM, this should hide the Host OS.
This image shows you where you can find the option:
If this is not what you are looking for, please elaborate on your problem, maybe add a screenshot showing the problem you are having.
I just experienced this exact problem, namely Windows 10 host taskbar would not go away despite the guest being in full screen. Even though this question is old, since this question got the top google page rank, I thought I would share how I fixed it.
I fixed it by shutting down Virtualbox and then rebooting the Windows 10 host. It is possible as others have pointed out that some app was keeping the taskbar active, but I couldn't find any such app. If it was some rogue app that was just running as a process (with no taskbar presence), the reboot nuked it from orbit and fixed the problem.
After installation virtualbox tools You can press
host + F (in my case Ctrl + F)
buttons to run fullscreen in virtualbox.
I'm trying to make a Win 7 64 bit guest machine. When it's time to load the ISO, I try to load it and I get the following error
The VM session was aborted.
Result Code: E_FAIL (0x80004005)
Component: SessionMachine
Interface: ISession {7844aa05-b02e-4cdd-a04f-ade4a762e6b7}
What's a fix for this? Thank you.
I have the same issue, and hopefully there will be a bug-fix for it soon.
In the meantime, I have managed to start the install process (in my case for Linux mint 17.2 rather than windows) by attaching the .iso image in the VirtualBox IDE Storage Settings page rather than the "mount" dialog that causes the error.
Open the settings for your VM in the VirtualBox UI, go to Storage, click on the "empty" entry in the list of IDE Controllers, and select the disk icon over to the right of the screen. Finally, select to "Choose Virtual Optical Disk File", and select your .iso of choice. Then start the VM and it should boot just fine.
I hope it helps for your case too!
update the extension pack was my solution
Maybe it will help.
I turned off sound card , and at virtual machine I had "audio" controller turned on.
When I turned off audio controler virtual machine start normaly.

Backed up the last saved snapshot from C:\Users\\VirtualBox VMs\Ubuntu\Snapshots
Go to Machine> Ignore last saved state.
Restart VM.
This worked.
This issue most likely happened for me because my Windows 10 randomly restarted a couple of time, with BSOD.

Menu -> Machine -> Reset all warnings
worked for me
Menu -> Machine -> Discard Saved State...
This worked.
start your virtual machine
start ubuntu
open settings in ubuntu and go to display
set resolution to 16:9
and you are done
