HA Core Installation, virtualization and Hyper V Error


Our company is trying to implement an IOT project using Home Assistant, but we tried to install it by using VirtualBox and got the following error: e_fail: 0x80004005 and couldn’t proceed with the installation process.
Now we are trying to install the Home Assistant Core on our virtual machine using Debian OS, and got the following message: error:0x80370102 due to enable virtualization.
As we are operating by a VirtualMachine, we don’t have access to the configuration to Enable or Disable Hyper-V or Virtualization options. Is there another solution to install HomeAssistant or something to solve any of those situation?
Extra: we are following this video for the Core Installation http://youtu.be/klgqCUkfc3w
