Hi Team,
NVIDIA vgpu mdev/mediated devices are getting deleted/removed after VM shutdown with
ovirt. How I can make them persistent even after VM shutdown/poweroff ? I want to set some
vgpu parameter in file /sys/bus/mdev/devices/vgpu-id/nvidia/vgpu_params for testing to
mdev. But can't do as uuid of mdev are not persistent. mdev are not there in
/sys/bus/mdev/devices/ after VM shutdown. We were using RHV/Red Hat Virtualization Host
4.4.10 host with NVIDIA vGPU. virsh commands are helping. Can you please help?
As from oVirt 4.5, you can set such parameters via oVirt's UI/API, see:
https://bugzilla.redhat.com/1987121
(The mdev devices were also changed to managed devices in order to
have them persisted)
