@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 nfsd

Now 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_ID

As well make sure to set the network up as bridge (veth instead of venet) so wake on lan and multicast will work properly.
