@Daan To use FOG within a proxmox OpenVZ container you need to make sure NFS is loaded an enabled on the host system first:
# lsmod | grep nfsd nfsd 312315 14 # grep nfsd /proc/filesystems nodev nfsdNow enable NFS for the container as well ($CONTAINER_ID is just a variable, put in the real ID of your container):
# vzctl stop $CONTAINER_ID # vzctl set $CONTAINER_ID --feature nfsd:on --save # vzctl start $CONTAINER_IDAs well make sure to set the network up as bridge (veth instead of venet) so wake on lan and multicast will work properly.
