Trouble attaching Intel HD 530 from linux host to win7 guest via PCI passthrough.

[walmartshopper12]

I have an intel 6600k with HD 530 graphics. z170 chipset. I have a GTX 1070 running my arch linux host displays. I would like to use PCI passthrough to attach the intel graphics to the win7 guest. So I ran the modifyvm --pciattach command with no errors and booted up the guest. Windows detected the new hardware and downloaded and installed the HD 530 driver. In device manager, it says the device could not start because there are not enough resources. So I tried disabling the virtualbox display adapter and rebooting. However when I rebooted, it hard locked my host. I could not even use the magic sysrq shortcuts to reboot. I tried two more times shutting down and rebooting the guest, but it hard locks the host every time. I wanted to do further testing to try to get the guest to enable and use the HD 530 card, but I don't want to risk losing data from the hard lockups, so I have stopped testing and detached the device.
