Hi,
LXD - 3.0.3
lxc start guidisco - ubuntu 19.04 with mate
get this massage
Error: Common start logic: Failed to retrieve mode of device /dev/nvidiactl: open /dev/nvidiactl: no such device or address
Sounds like you somehow have a /dev/nvidiactl device on your host but without the nvidia driver properly loaded/functional.
Can you show lxc config show --expanded guidisco as well as nvidia-smi?

Is there some black list where you can insert some devices, so container ignore them ?
Containers don’t normally rely on host devices, though in your case, you do have a gpu device which then requires LXD be able to access all GPU and GPU related devices on the host to set it up, including /dev/nvidiactl.
It sounds like your NVIDIA setup is currently non-fonctional on the host, fixing that will fix the container. Alternatively, if you don’t use the NVIDIA GPU, you can tell LXD to only pass whatever other GPU you have, which should get you rid of that error.
ok, i hind your answer for familiar topic here
I check my intel card and pass command
lxc config device add gui1404 gpu0 gpu pci=0000:00:02.0
but I get still
Error: Common start logic: Failed to retrieve mode of device /dev/nvidiactl: open /dev/nvidiactl: no such device or address
What I doing wrong ?
input/output error suggests some weird kernel issue, anything in dmesg?
