Here, select the processor at the top of the section and raise the slider until the minimum number of CPUs is two. Right-click your virtual machine, select Settings, and then go to the System tab. If you experience freezing, you may want to increase the number of CPUs to 2 to 4. However, VirtualBox, by default, will only display a virtual CPU, proven to cause problems with Ubuntu, especially recent versions. Here, click the Display tab and make sure that the Enable 3D Acceleration option is not selected.Īlthough regular computers only have one physical CPU, they still have multiple cores (cores) that act like many CPUs. In the left menu in VirtualBox, right-click on the Ubuntu virtual machine in which you are having trouble, then select Settings. If you encounter freezing, this is one of the first things you should try to disable.
While it may sound attractive, it rarely helps you achieve any real performance. Whether you are running Windows, macOS or even Linux, 3D Acceleration can cause problems in VirtualBox. If this happens to you, trying to figure out what the problem is can be a hopeless effort. This is especially true if you are running Ubuntu and it freezes continuously. Virtual machines are complex things and when something goes wrong, it's hard to know where the problem is. VirtualBox is one of the most popular virtual machines for many reasons, one of which is because it's free. Today I turned it back on, without changing anything, and now the SAME problem is going on.Īre there other ways that I can successfully run Linux on my Windows 8? I really need this.If you're curious about Linux but don't want to completely replace macOS or Windows, running this operating system in a virtual machine is a great choice. Please let me know if you have any ideasĮDIT: Okay, I reinstalled everything, went through all the trouble to get the main files I needed working, and everything worked fine yesterday. I tried pressing Esc and all the other things suggested here:īut nothing seems to work. So I really need ideas on what I can try doing so my Ubuntu VM actually boots.
I have a lot of stuff set up on VirtualBox and really don't want to go over that again. So now, even when I go back to the original settings – and even lower ones – it gets stuck on the same screen over and over again.
Right before it gets there, though, a " SMBbus base address not initialized" text message appears. until I decided to try to up its performance by changing a couple of settings.Īfter I tried these changes, my Ubuntu VirtualBox keeps getting stuck on the startup screen. So my Ubuntu VirtualBox was working fine.
