I am running ESXi 5.5 on a home system. When I attempt to pass one of the onboard SATA controllers (Intel ICH10R) to a VM, it is successful. However, the controller never appears in the VM. What else am I missing that would cause a VM to not recognize the controller? Additional Info: The controller is set to AHCI mode in the BIOS Prior to setting up the controller for passthrough, ESXi did recognize the controller and the drives I have tried with multiple VMs, none of which recognized the controller or the attached drives I have two onboard SATA controllers, on controller for ESXi and one for passthrough The final ideal state is that I could passthrough the controller to a FreeNAS VM
