What this episode proves
- Validate a declarative guest inventory before changes
- Provision multiple predictable guests
- Rerun with no duplicate resources or identity drift
- Run scoped cleanup against only the episode prefix
Validated workflow
1. Validate a declarative guest inventory before changes
./deploy-fleet.sh inventory.tsv ~/.ssh/id_ed25519.pub
2. Provision multiple predictable guests
virsh list --all
3. Rerun with no duplicate resources or identity drift
./deploy-fleet.sh inventory.tsv ~/.ssh/id_ed25519.pub
4. Run scoped cleanup against only the episode prefix
./cleanup-fleet.sh inventory.tsv
Finished state
The idempotent provisioning and cleanup scripts remain; proof guests are removed. The public scripts contain no private keys, passwords, or tokens. Review names, addresses, paths, ownership, backups, quorum, and fencing for your own environment before running them.
