CentOS virt - Oct 2011 - Strange problem with guest having more than 3 virtual interfaces.

Hi,

I have 6 DomU's with 4-virtual interfaces and 1 DomU with only one. When 
starting the DomU's in order where the domain with only one interface is 
started last it refuses to start with following error. If I start it 
first there is no problem starting them all.
