Hi, personally i’m using a MacBook with VirtualBox of Window 10. I have allocated 100GB storage size for my VirtualBox. Even though I can see Virtual Size is 100GB and Actual Size is 18.56GB and it has a maximum of 20GB but somehow i can’t use the Virtual Size. Immediately after switching back from the running VM (so I could see the htop display), I found that VirtualBox was using 50% of my CPU to run my idle VM. While sitting on the mac side, it's showing 30-35% CPU with excursions much higher (I saw 100+%). All this time, the VM was idle. 15 minute load average on the mac is 3.56. VirtualBox virtual machines are slow, thanks to the default VM configuration. If you use VirtualBox to run Linux, you may notice that performance isn’t great, and are looking for ways to improve it. It is possible to improve your Linux VM’s performance by tweaking settings in VirtualBox. Vboxvideo vboxsf vboxguest Everything works fine in Debian, except that the system is extremely slow. Even the mouse cursor lags when moved around, on a clean system with nothing running. Moving around applications take seconds.

If your log contains these lines:
or
This is because a service that uses Microsoft Hyper-V is running on your host PC.
Windows Home users:
Hyper-V exists on Home too, and several services can be made to use it. Only the ability to run Hyper-V virtual machines is not available in Home.
About the 'Windows Features' box:
Microsoft changes the names of things in their 'Windows Features' box at times. You may not specifically see a 'Hyper-V' checkbox, but anything based on the underlying Hyper-V hypervisor will turn on Hyper-V and cause trouble. Generally, trying to disable Hyper-V by unchecking boxes in 'Windows Features' often does not disable Hyper-V.
You might notice in the guest window's Status Bar the green turtle: The choice of animal is appropriate: Your guest is running, just really slow. Or it might guru-meditate or crash. Or guest OS's won't properly hash their update files or ISOs.
Normally Hyper-V blocks Virtualbox. Hyper-V is a type-1 hypervisor, which accesses the hardware first before any OS runs, and therefore interferes with other programs that need 'virtualization technology', like Virtualbox, which is a type-2 Hypervisor.
Your PC is of the type and OS where Virtualbox can attempt to run the guest using the Hyper-V engine. This arrangement is still being developed and isn't 100% yet.
If VirtualBox is running without Hyper-V enabled, and nothing else is interfering with hardware virtualization (VT-x / AMD-V), then the usual virtualization icon () will be seen in the Status Bar.
To turn Hyper-V off completely, do this:
1. Shut down all programs. You will have to shut down, unplug, and restart your host.
2. Look into I have a 64bit host, but can't install 64bit guests, 2nd post, points 2 & 3 and ensure that none of these things are running:
DeviceGuard
CredentialGuard
Windows Defender's Core Isolation
3. Find the Command Prompt icon, right click it and choose Run As Administrator.
4. Enter this command:

Virtualbox Performance Mac

bcdedit /set hypervisorlaunchtype off
Some report this command was needed also:
DISM /Online /Disable-Feature:Microsoft-Hyper-V

Virtualbox 6.1 Very Slow

5. Enter this command:
shutdown -s -t 2
6. When the computer turns off, unplug it for 20 seconds. Then plug it in again and boot up Windows 10.
Your Virtualbox should be running now. If the green turtle still appears and the tell-tale lines are in the log, try all the steps again. If you don't get the standard virtualization icon, post back exactly what you did and we'll try to help some more.
If your computer is running in a corporate environment with IT overlords, they may have forced Hyper-V, and none of the above will help. You will have to get IT to turn off Hyper-V so that you can run Virtualbox.
For further info, and a method to switch Hyper-V on or off at boot so you can run Hyper-V or Virtualbox (not both at the same time), see https://www.tenforums.com/tutorials/139 ... puter.html. Also see https://petri.com/how-to-disable-hyper- ... windows-10, found by user 'B1tm4p75'.
