Laurence Rowe (lrowe) wrote : Network is unreachable Wily ec2 c4 instance family

I've made several attempts to launch a c4.xlarge and c4.8xlarge instances using Ubuntu 15.10 Wily but am unable to ping the instance after it has started running. The console shows that the instance reachability check failed.

I am able to successfully launch c4.xlarge instances using Ubuntu 14.04 and t2.large instances using Ubuntu 15.10.

I've tried with both of these instance AMIs:

ubuntu/images/hvm-ssd/ubuntu-wily-15.10-amd64-server-20151021 - ami-225ebd11
ubuntu/images-testing/hvm-ssd/ubuntu-wily-daily-amd64-server-20151026 - ami-ea20cdd9

Might there be a problem with the Ubuntu Kernel in 15.10 for the c4 instances?

Looking at the system log it seems that the network never comes up:
