hello. My understanding is that the arp caching mechanism works regardless of whether you use static MAC addresses or dynamically generated ones.

Right, but, cacheing implies a timeout, and is there a timeout for the MAC addresses on Xen IFs? Does an `arp -an' indicate this (I can't test this-- no Xen set up.) -RVP
