Troubleshooting

Start with:

yeast doctor

Then gather:

yeast status
yeast logs <instance> --tail 100
yeast inspect <instance>

For automation:

yeast status --json
yeast inspect <instance> --json

Use the topic pages for specific failures.

Fast Triage

Ask three questions:

1. Did the host pass yeast doctor?
2. Did the project config validate?
3. Did the VM boot but fail later?

Useful commands:

yeast doctor
yeast status --json
yeast inspect <instance> --json
yeast logs <instance> --tail 120

Keep Evidence Before Cleanup

Before yeast destroy, capture:

yeast status
yeast inspect <instance>
yeast logs <instance> --tail 200

If you are reporting a bug, include the Yeast version:
