Could it still be an ARP related issue? I did a simplified version of the test this morning:
Try this test: since you have static IP- & MAC-addresses everywhere in your setup, just add them as static ARP entries (skip own address): On each of your DomUs and the Dom0: arp -d -a # delete ARP-cache arp -s IP-addr1 MAC-addr1 arp -s IP-addr2 MAC-addr2 etc. On the Dom0, add the addrs. of the DomUs. On each of the DomUs, the addrs. of Dom0 and _other_ DomUs. Do your tests. -RVP
