Working in a virtual environment, we are suggesting to choose one of the most common Hypervisor available, which are curently the following:

• VMware
  • VMware Workstation Player (Windows and Linux)
  • VMware Fusion (Non-Pro Version) (Mac OS)
    
    
• Oracle
  • Oracle VirtualBox (Windows, Linux and Mac OS)

Each of those hypervisors support the import of virtual machines (VMs) based on the file formats .ova and .ovf.

We at OST are providing different pre-prepared VMs VM images for different purposes.

To operate with a type 2 hypervisor, a computer's CPU (processor) must support hardware virtualization, which is the case for most any of modern CPUs. That said, it may be required enable the according option within the computer's BIOS, mostly within the „Advanced BIOS Features“ section or similiar. The according option to enable is typically called as one of the following:

• Intel VT-x
• AMD VT
• Virtualization
• VT
• Vanderpool Technology
• Virtualization Technology
• VMX
• Virtual Machine Extensions

In case you are using a physical Windows 10 computer and VMware Workstation Player version < 15.5 as a hypervisor, in some circumstances this combination can make you run into compatibility issues, caused by Microsoft's own virtualization platform Hyper-V. In such case, the following similiar error message will occur when trying to start the VM:

Error message

To fix this issue, you could try one of the following solutions:

• Check the following option during the installation of VMware Workstation if you are being asked for it (you are only being asked if the conitions are met):
  

  

  VMware Workstation optional installation step

  
  

• On your Windows 10 computer navigate to Control Panel → Programs and Features → Turn Windows features on or off → Disable Hyper-V

  

  
  

• Execute the following PowerShell command with administrative privileges:

  Disable-WindowsOptionalFeature -Online -FeatureName VirtualMachinePlatform

• Execute the following CMD command with administrative privileges:

  bcdedit /set hypervisorlaunchtype off

After troubleshooting, if your computer meets any of the conditions above, after a system reboot, the error messages should not ocoour anymore.
