Yes it does and it consumes valubale CPU and memory.
The question what happens in such a case.
Very simple answer... if you spin up a guest in a cloud, and it doesn't
get a network interface/ip address, you wait a bit (configurable) and
then you shoot it violently in the head. A guest in the cloud with no
network is not worth keeping around :)
