I just checked, each VM has a unique MAC address.

Host MAC address for e1000g1 (203.6.241.33):
(output from arp -an)
e1000g1 203.6.241.33         255.255.255.255 SPLA     68:05:ca:16:90:8f

for the VM's
203.6.241.132|134 (this virtual server has two IP addresses)
carl at hostie:~$ arp -an | grep 132
e1000g1 203.6.241.132        255.255.255.255          08:00:27:be:a9:97
carl at hostie:~$ arp -an | grep 134
e1000g1 203.6.241.134        255.255.255.255          08:00:27:be:a9:97

carl at hostie:~$ arp -an | grep 34
e1000g1 203.6.241.34         255.255.255.255          08:00:27:3f:d3:b2


carl at hostie:~$ arp -an | grep 35
e1000g1 203.6.241.35         255.255.255.255          08:00:27:85:b3:d6

All the MAC addresses are unique per VM's ethernet interface. All these 
arp outputs match the output from ifconfig on each of the guests.

That should happen automagically.  The guest should pick up the MAC 
address from Virtualbox.  It has in this instance.  If it didn't, I 
would see problems a lot earlier than after a week or so, right?

I'm not using VLANs, these are just bridged ethernet ports.  Unless 
*maybe* the problem is two IP addresses for the one ethernet on one of 
the servers?  That would have to be a bug if it is a problem, ethernet 
ports should be able to handle multiple IP addresses.



Am I on the right track? A bug or a misconfiguration?

thanks again,
