+Go to the CPUs page and remove the check next to `Copy host CPU configuration` and under Model type `host-passthrough`. Also make sure to check the option for `Enable available CPU security flaw mitigations` to prevent against Spectre/Meltdown vulnerabilities.

+I've chosen to remove several of the menu options that won't be useful to my setup (feel free to keep them if you'd like):

-### Part 3: Performance
+Let's add the virtIO drivers. Click 'Add Hardware' and under 'Storage', create a custom storage device of type `CDROM`. Make sure to locate the ISO image for the virtIO drivers from earlier:

+Under the NIC menu, change the device model to `virtIO` for improved performance:

+Now it's time to configure our passthrough devices! Click 'Add Hardware' and under 'PCI Host Device', select the Bus IDs corresponding to your GPU.

+Make sure to repeat this step for all the devices associated with your GPU in the same IOMMU group (usually VGA, audio controller, etc.):

+Since I'm passing through an entire disk to my VM, I selected the Bus ID corresponding to the 1TB Samsung NVMe SSD which has Windows 10 (and my games) installed on it.

+Then under the 'Boot Options' menu, I added a check next to `Enable boot menu` and reorganized the devices so that I could boot directly from the 1TB SSD:

+
+You can now go ahead and select the USB Host Devices you'd like to passthrough to your guest VM (usually a keyboard, mouse, etc.). Please note that these devices will be held by the guest VM from the moment it's created until its stopped and will be unavailable to the host.<sup>[10](#footnote10)</sup>

+Unfortunately, not everything can be accomplished using the virt-manager GUI. For the next several steps, we'll need to do some finer tuning by directly editing the XML:
