I think you've got two options:
1) You can use VETH devices instead of VENET. VETH is a more strict
seperation of the network stuff, and full IP configuration is
available in the VE.

2) _If_ you only want this VIP on _ONE_ host node, you probably can
manually set up routing and ARP on the host node for your VIP, and
then just use ifconfig inside the VEs. Haven't tried this out, but
I'd assume it works.
