Hi all,
i have an issue on my XenServer Host. Infact, after a reboot of this, i receive some permission errors like these:
[root@snsg02044 ~]# nvidia-smi
No devices were found. Please make sure /dev/nvidia* files are readable by current user.
[root@snsg02044 ~]# nvidia-debugdump --list
Found 1 NVIDIA devices
Warning: No permission to talk to device 0000:9F:00.0.
[root@snsg02044 ~]# nvidia-smi -L
Unable to determine the device handle for gpu 0000:9F:00.0: Insufficient Permissions
[root@snsg02044 ~]# lspci | grep NVIDIA
9f:00.0 VGA compatible controller: NVIDIA Corporation GK104GL [GRID K2] (rev a1)
a0:00.0 VGA compatible controller: NVIDIA Corporation GK104GL [GRID K2] (rev a1)
Only one Virtual machine succeeds to start correctly through gpu-passthrough while another one return this error:
No devices were found. Please make sure /dev/nvidia* files are readable by current user.
Before the host reboot, all works fine.
Can you help me?
Thanks
