Troubleshooting: One Windows 10 VM Freezing, Another One Opens in VirtualBox
In this article, we will discuss the common issues encountered when running two Windows 10 virtual machines (VMs) on VirtualBox 7.0.20, and how to troubleshoot them. Both VMs are given 8GB of RAM, 50GB of storage, 256KB of VRAM, and 4 cores each. The host machine has 64GB of RAM and 20 physical GPUs.
Windows 10 VM Freezing
One of the common issues encountered when running multiple VMs on VirtualBox is freezing. This can be caused by several factors, such as insufficient resources allocated to the VM, conflicts between VMs, or hardware compatibility issues.
Insufficient Resources
One of the most common causes of VM freezing is insufficient resources allocated to the VM. To avoid this issue, make sure that you have allocated enough resources to each VM. For instance, in this scenario, each VM is given 8GB of RAM, 50GB of storage, 256KB of VRAM, and 4 cores. If the host machine has sufficient resources, allocating more resources to the VM should resolve the freezing issue.
Conflicts Between VMs
Another possible cause of VM freezing is conflicts between VMs. This can occur when two or more VMs are competing for the same resources or when a VM is interfering with the host machine's hardware. To resolve this issue, try running one VM at a time or adjusting the settings of each VM to avoid conflicts.
Hardware Compatibility Issues
Hardware compatibility issues can also cause VM freezing. This can occur when the VM's hardware settings are not compatible with the host machine's hardware. To resolve this issue, try updating the VM's hardware settings to match the host machine's hardware or updating the VirtualBox software to the latest version.
Another Windows 10 VM Opens in VirtualBox
Another common issue encountered when running multiple VMs on VirtualBox is that another Windows 10 VM opens instead of the intended VM. This can be caused by several factors, such as incorrect VM settings, conflicting VM names, or issues with the VirtualBox software.
Incorrect VM Settings
Incorrect VM settings can cause another Windows 10 VM to open instead of the intended VM. To resolve this issue, check the settings of each VM and make sure that they are correctly configured. Pay particular attention to the VM's name, operating system, and hardware settings. If necessary, rename the VMs to avoid conflicts.
Conflicting VM Names
Conflicting VM names can also cause another Windows 10 VM to open instead of the intended VM. To resolve this issue, rename the VMs to avoid conflicts. Make sure that each VM has a unique name and that the names do not contain any special characters or spaces.
Issues with VirtualBox Software
Issues with the VirtualBox software can also cause another Windows 10 VM to open instead of the intended VM. To resolve this issue, try updating the VirtualBox software to the latest version. If the issue persists, try reinstalling the VirtualBox software.
- Insufficient resources allocated to the VM can cause freezing. Allocate sufficient resources to each VM to avoid this issue.
- Conflicts between VMs can also cause freezing. Run one VM at a time or adjust the settings of each VM to avoid conflicts.
- Hardware compatibility issues can cause VM freezing. Update the VM's hardware settings to match the host machine's hardware or update the VirtualBox software.
- Incorrect VM settings, conflicting VM names, and issues with VirtualBox software can cause another Windows 10 VM to open.

virtualbox startvm <VM\_name> --type headless
The above command can be used to start a VirtualBox VM in headless mode. This will allow you to run the VM in the background without displaying the VM's graphical interface. This can be useful if you want to run multiple VMs at the same time or if you want to automate the VM's operation.
