How to restart a frozen LXD container

This article provides a How-to guide for restarting a container in a cluster with the LXD virtualization type. If the container is frozen, any actions on it will be blocked. For example, starting or deleting VMs.

 To restart the container:

1.  Connect to the faulty node via SSH.

2. Find the ID of the faulty process:

   ps -eF | grep '<container_name>' | grep 'lxc monitor'

   Comment

   <container_name> — name of the frozen LXD container

3. Disable the faulty process with the command:

   kill -9 <PID>

   Comment

   <PID> — ID of the faulty process

After these actions, the container will resume operation. Perform the required action, such as starting or deleting a VM from the VMmanager web interface.
