Virtual machines are complex things, and when something goes wrong, it are often tough to inform where the matter lies. this is often very true if you’re handling Ubuntu freezing in VirtualBox. If this is often happening to you, trying to work out what the matter is are often an exercise in frustration. Here are some ways you’ll use to repair the Ubuntu freezing in VirtualBox issue.
Try a Different Version of VirtualBox
No program is freed from bugs, and this goes for both Ubuntu and VirtualBox. Some users have found that different versions of VirtualBox and Ubuntu sometimes just don’t get along. If a particular version of Ubuntu never froze within the past, you’ll try installing an older version of VirtualBox.
Conversely, you would possibly try running a more moderen version of Ubuntu. Not only will you most likely solve your freezing problem, but you’ll get new features also .
Alternately, if you started using VirtualBox with a more moderen version of Ubuntu, check to ascertain if there are any freezing issues thereupon version. for instance , if you look for “Ubuntu 20.4 LTS freezing” on Google, you’ll see tons of complaints. So, the matter could easily be with Ubuntu and not VirtualBox. Installing an earlier version of Ubuntu may help eliminate the freezing issue.
Disable 3D Acceleration
No matter whether you’re running Windows, macOS, or maybe Linux, 3D acceleration can cause many problems in VirtualBox. While it seems like something you’d want, it rarely enables any actual gains in performance. If you’re encountering freezing, this is often one among the primary things to undertake turning off.
In the menu on the left in VirtualBox, right-click on the Ubuntu virtual machine you’re having problems with, then select Settings. Here, click the Display tab and confirm that “Enable 3D Acceleration” isn’t selected.
Change the Number of Virtual CPUs
Though computers sold to consumers typically have just one physical CPU, they need multiple cores that act like multiple CPUs. Even so, VirtualBox, by default, will only expose one virtual CPU, which has been shown to cause problems with Ubuntu, especially recent versions.
If you’re encountering freezing, you’ll want to bump the amount of CPUs up anywhere from two to four. Right-click on your virtual machine, select Settings, then attend the System tab. Here, select processor at the highest of the section and lift the slider until the amount of CPUs is a minimum of two.
Reduce RAM Usage
If Ubuntu freezing in VirtualBox only happened occasionally, it might be a RAM issue. The host computer only has such a lot RAM. albeit VirtualBox allows you to run another OS , it’s still using your computer’s resources. If you’re trying to run apps on your main OS and Ubuntu at an equivalent time, it could end in freezing on Ubuntu and/or your main OS.
Ideally, limit your main OS usage when using Ubuntu on VirtualBox. If you would like to try to to something more memory intensive on your main OS, close up Ubuntu or close any running programs thereon to scale back RAM usage. this is often very true if you’ve got an anti-virus scan going.
If you’ve recently upgraded to a replacement version of Ubuntu, it’s possible the remake requires more resources than a previous version. this will end in freezing.
Upgrading the RAM in your computer is that the best solution if you merely don’t have enough to support two operating systems.
As a final resort, you’ll got to reinstall Ubuntu. If the freezing issue occurs frequently after the first installation, it might be that the system didn’t install correctly. Also, if the freezing occurs mainly upon boot, the difficulty is probably going with the installation.
If reinstalling Ubuntu isn’t an option for you, then attempt to update Ubuntu from the recovery mode. The previous software update could have some corrupted packages that cause the system to freeze. they’re usually fixed very quickly, so always run an update to urge the newest version of all packages.
Other Options to undertake with VirtualBox
There are another options that users have found solved their problems with freezing. within the same section where you’ll change the amount of CPUs, there’s an choice to “Enable PAE/NX.” Toggling this off if it’s on already, or on if it’s already off, could solve your problem.
You can also try changing your paravirtualization settings. attend Settings, then select “System and Acceleration” below it. Paravirtualization Interface will likely be set to “Default,” but some users have had better results setting it to “Minimal.”
Frequently Asked Questions
Does VirtualBox support all versions of Ubuntu?
Yes, as long as you’re using the official stable version. If you’re running a beta version of Ubuntu, it’d not add VirtualBox, and there’s a better risk of freezing and other issues. In some cases, with 64-bit versions, you’ll got to disable Hyper-V to avoid problems.
How am i able to choose the proper amount of RAM?
Since RAM may be a major concern to stop freezing and just a poor overall experience, it’s best to make sure you allocate a minimum of the minimum amount of RAM needed to run Ubuntu to your VirtualBox instance. If this is often all of your RAM, you ought to consider upgrading your PC. you ought to allocate a minimum of 2GB.
Does the amount of processors matter?
This is a difficult one. Users report changing the amount of processors allocated to their Ubuntu installation can help with the freezing issue, but this isn’t a guarantee. There isn’t one set number that works for everybody as some users change from 1 to 2 or 2 to 1 and both options fixed their freezing issue. It’s an choice to try but might not help in the least .
