In your systems file, I do not see a MAC set for the first interface, 
just the second.

Any chance it was created with --mac1=value versus --mac=value?

I can duplicate your problem with the first interface remains empty. 
This is most definitely
a bug, though probably one that few people would encounter.

I'll put in a fix. In the meantime, you can edit that file to add the 
interface to the 'intf0' part
and delete the entirity of 'intf1' part, and it will work fine. If you'd 
rather not worry about
tweaking the config files, the Web UI can also do this.

Hope that helps... I'll file a defect on this on the Trac page.
