If the VM gets its network configuration from metadata instead of 
DHCP/SLAAC+RA and isn't relying on configdrive and isn't falling 
back to using network settings cached into /etc from a prior boot 
(and is running on a non-amd64 arch), then it can come up with no 
reachable network. That combination of factors should be 
exceptionally rare however.

The more likely scenario, you're right, is that updated images fail 
when trying to create and boot a new VM from them for the first 
time, but that's probably far less problematic since users can 
typically roll back to an older version of the image or adjust their 
options to e.g. turn on configdrive when available.
