When doing "sudo reboot" in an instance shortly followed by "euca- reboot-instances {instanceID}", once the instaces comes back up, it is no longer accessible interactively. The kernel is still executing commands but it stucked in the early boot phases If only "sudo reboot" from within the instance or "euca-reboot- instances" is used, network connectivity comes back as expected. This can be reproduced by using the following steps : # On the compute node sudo -s source creds/novarc # start instance instanceid=`euca-run-instances -k novaadmin -t m1.tiny ami-00000006 | grep INSTANCE | awk '{print $2}'` # wait for instance to start sleep 60 # reboot the instance with reboot command ssh -i creds/novaadmin_.key ubuntu@`euca-describe-instances $instanceid | grep INSTANCE | awk '{print $4}'` 'sudo reboot' # wait 20 seconds sleep 20 # reboot instance with euca-reboot-instance command euca-reboot-instances $instanceid Now euca-describe-instances will show the instance as running, but it is is unreachable via ssh. The kvm process for the instance is still visible and running.
