0.2.1 Stability matters

This minor release improves the stability of the software.

0.2.0 Resource monitoring

This new release introduces the monitoring of the resources used by VMs, changes where files are stored on the system, and introduces multiple fixes and improvements.

Monitoring of VM resources

• Feature: Record VM execution times and log details on files. by @hoh in #150

Execution times of VMs that stopped can be fetched on https://{host}/about/executions/records. Resource usage of running VMs can be fetched after authentication on https://{host}/about/executions.

Execution times are stored by default in /var/lib/aleph/vm/executions.sqlite3 (settings.EXECUTION_DATABASE).

Breaking changes

• Aleph-VM files are now stored in /var/lib/aleph/vm:
  • /srv/jailer → /var/lib/aleph/vm/jailer
  • /var/tmp/aleph/volumes → /var/lib/aleph/vm/volumes
• The supervisor cache moved from /tmp/aleph/vm_supervisor to /var/cache/aleph/vm
