Red Hat Bugzilla – Bug 1285799
[RFE] - Document hostdev_passthrough and VFIO features in RHEV administration guide.
Last modified: 2016-03-16 10:17:30 EDT
Description of problem:
In order to use both hostdev_passthrough and VFIO features, there are some limitations and preparations that needs to be documented.
Limitations example: host BIOS must support Intel vt-d or AMD-vi and host kernel should be >= 3.6
Setup preparation example: IOMMU support should be enabled, host GPU vendor:device ids should be added to pci-stub and GPU driver should be blacklisted.
Also, webadmin procedure for these features and feature limitations should be documented in the admin guide.

Assigning to Andrew for review.
*** Bug 1247578 has been marked as a duplicate of this bug. ***
This is going to involve new topics in the VMM and Admin Guide to cover the new GUI elements, and an admonition to VM migration topics in the VMM guide (those marked with * are still wip)
New section - Host Devices (in Administrative Tasks)
-*Device Passthrough concept - link to hardware considerations art.
-*Additional requirements for GPU passthrough (probably concept + proc.)
-Adding a Host Device to a Virtual Machine
-Removing Host Devices from a Virtual Machine
-Pinning a Virtual Machine to Another Host
Admonition added to:
-Preventing Automatic Migration of a Virtual Machine
-Viewing Host Devices
Also, partially related, notice that there's no docs bug to cover SR-IOV in the GUI so will raise one out of BZ#869804
Looks great - thank you! Changes have been merged, added Revision History entries to the Admin Guide and VMM Guide.
