Public bug reported: 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: [ 140.699509] cloud-init[1469]: 2015-10-26 20:45:49,887 - url_helper.py[WARNING]: Calling 'http://169.254.169.254/2009-04-04/meta- data/instance-id' failed [0/120s]: request error [('Connection aborted.', OSError(101, 'Network is unreachable'))] Thread at AWS forums: https://forums.aws.amazon.com/thread.jspa?threadID=218656 ** Affects: ubuntu Importance: Undecided Status: New ** Tags: ec2 wily ** Attachment added: "System log from EC2 console" https://bugs.launchpad.net/bugs/1510345/+attachment/4506229/+files/c4-system.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1510345 Title: Network is unreachable Wily ec2 c4 instance family To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1510345/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
