Doc Text:
This update adds a new VDSM hook called vdsm-hook-vfio-mdev that makes the host capable of working with mdev capable devices such as GPUs. The hook is automatically installed. The following prerequisites apply for a virtual machine to use a mdev instance: 1) The host must have a kernel that supports mediated device, have the device and the correct drivers. 2) The predefined property, 'mdev_type', must be set and correspond to one of the mdev types supported by the device. 3) The virtual machine must be pinned to the host(s) with the device(s). The supported mdev_type values can be determined by checking the host on which the device is present (not visible in the engine) by querying vdsm (vdsm-client Host hostdevListByCaps) or running the following bash script: for device in /sys/class/mdev_bus/*; do for mdev_type in $device/mdev_supported_types/*; do MDEV_TYPE=$(basename $mdev_type) DESCRIPTION=$(cat $mdev_type/description) echo "mdev_type: $MDEV_TYPE --- description: $DESCRIPTION"; done; done | sort | uniq

Comment 1 Michal Skrivanek 2017-04-25 06:54:05 UTC 
such hook should be obsoleted/removed in 4.2
Comment 2 Michal Skrivanek 2017-04-27 11:01:23 UTC 
let's build a vdsm hook to utilize the latest enhancements for vGPU mediated device(mdev) in qemu and libvirt, and make it available as an unsupported hook.
