Virtualbox ubuntu kernel panic serial#

Choose Instances from the navigation pane, and then select the impaired instance.ģ. It's a best practice to use an Elastic IP address instead of a public IP address when routing external traffic to your instance.Ģ.

When you stop and start an instance, the public IP address of your instance changes.

If your instance is part of an Auto Scaling group, temporarily remove the instance from the Auto Scaling group before starting the resolution steps. Check the instance scale-in protection settings for your Auto Scaling group. Some AWS services use EC2 Auto Scaling to launch instances, such as Amazon EMR, AWS CloudFormation, and AWS Elastic Beanstalk.

If you launch instances using EC2 Auto Scaling, stopping the instance might terminate the instance.

For more information, see Determine the root device type of your instance. Be aware that if your instance is instance store-backed or has instance store volumes containing data, the data is lost when you stop the instance.

This procedure requires a stop and start of your EC2 instance.

Note: If you receive errors when running AWS CLI commands, make sure that you're using the most recent version of the AWS CLI.

For information on configuring the EC2 Serial Console for Linux, see Configure access to the EC2 Serial Console.

If your instance is unreachable and you haven't configured access to the serial console, follow the instructions in Method 2: Use a rescue instance. Also, every instance using the serial console must include at least one password-based user. Then, create AWS Identity and Access Management (IAM) policies granting access to your IAM users. You can access the serial console using the Amazon EC2 console or the AWS Command Line Interface (AWS CLI).īefore using the serial console, grant access to it at the account level. The serial console connects to your instance without the need for a working network connection. The serial console helps you troubleshoot boot issues, network configuration, and SSH configuration issues. If you enabled EC2 Serial Console for Windows, then you can use it to troubleshoot supported Nitro-based instance types.

If you have hosts in AWS, GCP, Azure, and Oracle Cloud running containers and Ubuntu 20.04 - you will want to check on your kernel upgrades and hold off on updating until Ubuntu and the Cloud Providers roll out a fixed kernel.Use one of the following methods to correct this:

Those hosting a docker-based GitLab installation that’s set to start automatically and has been updated to one of the affected kernels.GitLab Runners using the Docker+Machine executor trying to launch an Ubuntu 20.04 instance with an updated kernel to host docker-based builds and not being able to connect to the docker-machine launched vm.Gitlab Runner hosts using the docker executor and crashing when trying to launch the helper/build containers.We’ve seen a kernel bug/panic triggered in internal testing when trying to run a container on Ubuntu 20.04 with one of the recently updated cloud provider optimized kernels.
