Hi@pam,

There are few reasons behind this error. Le's discuss these.

  • Check VT-X is enabled in the BIOS settings or not. If not than enable it.

  • Check if Hyper-V virtualization is enabled in Windows. This is the most common cause why this error occurs. Since .Microsoft’s Hyper-V technology is known to conflict with VT-X, the OS will automatically disable VT-x if Hyper-V virtualization is enabled. To disable this use the bellow command from Windows PowerShell. 

  dism.exe /Online /Disable-Feature:Microsoft-Hyper-V
  • Disable Core isolation from Windows Defender.

Hope these steps will solve the error.

Thank You

This may be due to the Virtualization option is not enabled for the CPU in the local machine's BIOS and this is required since Hipchat Server guest OS is 64-bit.

  • Enable the Virtualization option in the local machine BIOS and restart the computer.
  • If the BIOS does not have a Virtualization option or it is already enabled, please see this virtualbox forum post for additional workarounds.
Hope this will help to resolve your issue.
