[libvirt] need custom /dev entries in LXC

Hi, We run nvidia devices inside libvirt-managed LXC containers. It used to be that simply doing: $ echo 'c 195:* rwm' > /sys/fs/cgroup/devices/libvirt/lxc Then, after booting the container, we would do: $ mknod -m 666 /dev/nvidia0 c 195 0 .... would be good enough to run our CUDA applications. But, according to: $ cat src/lxc/lxc_container.c The CAP_MKNOD capability is being dropped and only a specific set of devices is being created before booting the container. Is there any reason why this is not per-device configurable? Thanks, - Michael R. Hines
