Introduction

Two Windows 10 virtual machines (VMs) created using VirtualBox 7.0.20 have been freezing during use. Each VM was allocated 8 GB RAM, 50 GB storage, 256 MB VRAM, and 4 cores. The host machine has a 64 GB RAM, ensuring sufficient resources for both VMs. In this article, we will discuss possible causes and solutions for this issue.

Check System Requirements

First, ensure that the host machine meets the minimum system requirements for running VirtualBox and the guest operating systems (Windows 10). VirtualBox's official website provides a detailed list of the requirements: https://www.virtualbox.org/wiki/System_requirements

Update VirtualBox

Check if there is an available update for VirtualBox 7.0.20. Updating VirtualBox may resolve any known issues or bugs that could be causing the VM to freeze. Visit the VirtualBox downloads page: https://www.virtualbox.org/wiki/Downloads

Install or Update Guest Additions

Ensure that the Guest Additions are installed and updated in both VMs. Guest Additions improve the performance and compatibility between the host and guest operating systems. Install the Guest Additions from the Devices menu in VirtualBox: Devices > Install Guest Additions...

Check VM Settings

Verify that the settings for both VMs are correctly configured. Check the following settings:

  • System > Motherboard > I/O APIC: Enabled
  • System > Processor > Number of Processors: Corresponds to the number of cores allocated
  • Display > Screen > Video Memory Size: Corresponds to the allocated VRAM

Check Hardware Compatibility

Check the hardware compatibility between the host and guest operating systems. VirtualBox provides a list of supported guest and host operating systems: https://www.virtualbox.org/wiki/Compatibility_Matrix

Troubleshooting

If the issue persists, try the following troubleshooting steps:

  1. Restart the host machine and the VMs.
  2. Allocate more resources to the VMs.
  3. Disable 3D acceleration in the VM settings.
  4. Disable Hyper-V on the host machine.
  5. Create a new VM and transfer the data from the old VM.

Summary

In conclusion, if you encounter issues with two Windows 10 VMs freezing in VirtualBox 7.0.20, first ensure that the system requirements are met, update VirtualBox, install or update Guest Additions, check VM settings, and verify hardware compatibility. If the problem persists, follow the troubleshooting steps provided.
