Description Michal Skrivanek 2014-05-21 07:09:46 UTC

we should support a proper hostdev passthrough. Replacing/fixing/enhancing the existing hostusb hook(see http://gerrit.ovirt.org/#/c/14237/) with built-in device reporting,selection in UI, hotplug...

Comment 1 Michal Skrivanek 2015-06-15 14:24:30 UTC

(see bug 1231808 for missing REST, to be added)

Comment 2 Nisim Simsolo 2015-11-26 13:15:39 UTC

bug https://bugzilla.redhat.com/show_bug.cgi?id=1234283 removed from block since it's an RFE for supporting passthrough hotplug and not relevant for this bug.

Comment 3 Nisim Simsolo 2015-11-26 13:31:50 UTC

Verified.
hostdev_passthrough of PCI and USB tested alongside VFIO passthrough.
Test plan added to external trackers.

Note: ovirt feature page (http://www.ovirt.org/Features/hostdev_passthrough#GPU_passthrough) is good but we also need to verify it will be documented in admin guide since there are some requirements and setup preparation that must be performed in order to use hostdev_passthrough (such as BIOS support for intel vt-d/AMD-vi, enabling IOMMU support, pci-stubbing and blacklisting kernel drivers).

Since oVirt 3.6.0 has been released, moving from verified to closed current release.
