I'm marking this "In progress" based on the intent to backport to 12.04.
The fix for this bug is already present in the cloud images in 12.10.
** Description changed:
This issue has been reproduced on Diablo and Essex so far.
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.
