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) > _______________________________________________ > Users mailing list -- users(a)ovirt.org > To unsubscribe send an email to users-leave(a)ovirt.org Privacy > Statement: https://www.ovirt.org/privacy-policy.html > oVirt Code of Conduct: > https://www.ovirt.org/community/about/community-guidelines/ > List Archives: > https://lists.ovirt.org/archives/list/users@ovirt.org/message/YAZ5I5LT > FZ3WXBPVNIPH2HQWVEDSQW6K/
