The node will arp reply for 1.2.3.4 if and only if
ip r g 1.2.3.4 from [your_ip] dev [incoming dev]
will return a route _OTHER_ than one to [incoming dev]

So in our case HN have to reply if we have appropriate record in our route table. Please, check that you have it (I mean something like VE_IP dev venet0 scope link src HN_IP
I have the following assumption:
in spite of the fact that we have that routing entries our proxy_arp variable (I mean /proc/sys/net/ipv4/conf/eth0/proxy_arp) is set to be 0. So HN doesn't response. But during the VE staring vzctl put appropriate proxy arp records and that is why HN can responce to VE_IP arp requests. So we can add this record manually like vzctl utility does. (on HN)ip neigh add proxy VE_IP dev eth0
But who flush these records? I don't know.

As far as I know NIC doesn't sent them.
