Try: arp -vn 

It should show a line with your VE IP address, like this:

10.10.150.244       *    <from_interface>    MP       eth0

If you don't have such a line, the host node will not respond to ARP
queries (except if you turn on proxy_arp, but I'd advise against 
this).

The VE start script sets this up (so a restart will fix it), but
I've also seen cases where these entries get lost after some time.
Haven't been able to produce a test case, though.

Any chance that you are using a firewall on the host node which
fiddles with the ARP stuff? (shorewall?)

Christian
