I investigated some more. I found that OpenVZ does ARP updates on
network interface addition by itself ... 

--
File /usr/lib/vzctl/scripts/vps-functions 
# Send ARP request to update neighbour ARP caches
function vzarpipset()
--

However this is only called by /usr/lib/vzctl/scripts/vps-net_add

So to call this when a machine starts, I will try to add it to 

  /etc/vz/conf/vps.mount

Which is executed every time a machine is started. (I already use that
hook to add the HOST "hostname" to the VE's, so that they know "where
they are running").

So thanks, I will try the "simple script withing OpenVZ" way first. But
thanks anyway.
