Lab Infrastructure

Multi-lab coexistence

• --lab-down config.yaml: stops VMs (stay on disk).
• --lab-up config.yaml: starts stopped VMs (refuses if media attached).
• --cleanup: destroys permanently. These are distinct operations.
• --resources: host RAM/CPU/storage + per-pool allocation (API only).
• --labs: scans pool for [incusos-lab:managed] VMs, groups by config.
• --lab-up auto-deploy: offers full pipeline if no VMs exist yet.

VMID range convention

Range	Lab
400-499	OC-managed nodes
800-809	Single-node labs
900-909	Basic cluster
910-919	OC combined (server + nodes)
920-929	OC server standalone
930-939	Advanced / heterogeneous

Resource constraints

• RAM is the bottleneck: 4 GiB/VM minimum. 3-node = 12 GiB, OC lab = 28 GiB.
• Storage: thin provisioned (ZFS sparse). 3x 50 GiB = ~7-8 GiB actual.
• CPU: 4 cores/VM, 20 on host. Not a constraint.
• Pre-deploy checks warn if RAM exceeds available (API method).
