Eelco Dolstra	2e38d8cd31	* ZOMG, fixed a giant bug in the networking of distributed VM tests. It turns out that all network interfaces in all VMs had the same Ethernet address (52:54:00:12:34:56) because we didn't specify any with the macaddr=... option. This can obviously lead to great confusion. For instance, when a router forwards a packet, it can actually end up sending the packet to itself because the target machine has the same Ethernet address (causing a loop until the TTL expires), while the target also receives the packet. It's amazing anything worked at all, really. So now we just set the Ethernet addresses to 52:54:00:12:<virtual network number>:<machine number>. svn path=/nixos/trunk/; revision=25020	2010-12-07 00:44:29 +00:00

* ZOMG, fixed a giant bug in the networking of distributed VM tests.

It turns out that all network interfaces in all VMs had the same
  Ethernet address (52:54:00:12:34:56) because we didn't specify any
  with the macaddr=... option.  This can obviously lead to great
  confusion.  For instance, when a router forwards a packet, it can
  actually end up sending the packet to itself because the target
  machine has the same Ethernet address (causing a loop until the TTL
  expires), while the target *also* receives the packet.  It's amazing
  anything worked at all, really.

  So now we just set the Ethernet addresses to 52:54:00:12:<virtual
  network number>:<machine number>.
