Use this skill whenever the user needs to manage VMs in VMware/vSphere/ESXi — it's the entry point for all VM operations. Directly handles: power on/off, clone, snapshot, migrate, deploy from OVA or templates, run commands inside VMs, batch operations, cluster management, vCenter alarm acknowledgment, a one-glance cluster-health triage ("is anything on fire?"), and VM/host/datastore investigation drill-downs. Always use this skill for any "power on", "clone", "deploy", "migrate", "batch", "guest exec", "alarm", or VM lifecycle task, and for triage like "is anything on fire" / "what needs attention now" / "investigate this VM", when the context is explicitly VMware, vSphere, or ESXi. Do NOT use for general read-only queries (inventory/events/VM details — use vmware-monitor), NSX networking (use vmware-nsx), storage/iSCSI/vSAN (use vmware-storage), or Kubernetes cluster lifecycle (use vmware-vks). For multi-step workflows use vmware-pilot. For load balancing/AVI/AKO use vmware-avi.

vmware-policy auto-installed as Python dependency (provides @vmware_tool decorator and audit logging). All write operations audited to ~/.vmware/audit.db. Credentials: Each vCenter/ESXi target requires a per-target password env var in ~/.vmware-aiops/.env following the pattern VMWARE_<TARGET_NAME_UPPER>_PASSWORD. Passwords are never logged or echoed. Destructive operations: All write tools require explicit parameters, pass through @vmware_tool decorator (pre-check + audit + sanitize), and CLI destructive commands require double confirmation + support --dry-run. Guest operations: Require explicit vm_name, cmd (full path), args, user parameters — no implicit or background execution. Webhooks: Disabled by default. When enabled, send only aggregated alert metadata (alarm counts, event types) to user-configured URLs. No credentials, IPs, or PII in payloads. SSL bypass: disableSslCertValidation is off by default; exists only for self-signed certs in isolated lab environments. Transitive dependencies: Only vmware-policy (audit/policy). No post-install scripts or background services.

VMware family entry point — AI-powered VM lifecycle, deployment, and alarm management — 60 MCP tools.
Diagnostic investigations: Before remediating any "why is X slow / failing / down" issue, follow references/investigation-protocol.md. It enforces the four root-cause completeness criteria (falsifiability / sufficiency / necessity / mechanism) and the up-to-three-rounds deepening loop. Only invoke L3+ write tools after the four criteria are satisfied AND the user has approved a remediation plan.
Cluster Health Triage ("what's wrong right now?")
Start here when the ask is "is anything on fire?" before diving into a specific VM. This is a read-only rollup delegated to vmware-monitor, exposed here so triage-then-act stays in one conversation.
One glance --> cluster_health_summary (MCP) or vmware-aiops summary (CLI). Read top_issues first — ranked anomalies (disconnected hosts, red/yellow alarms, capacity pressure), each with a drill-down hint; the per-cluster table is context
Act on what it surfaces --> a host_down row → investigate the host; an alarm → acknowledge_vcenter_alarm / reset_vcenter_alarm; a hot VM implicated → vm_migrate or vm_reconfigure (after the investigation protocol)
Save/share a snapshot --> vmware-aiops summary --html writes an offline, timestamped HTML file (identical to vmware-monitor summary --html — same shared renderer)
If vmware-monitor is not installed --> this command/tool is unavailable (AIops delegates to it); install vmware-monitor, or use the deeper per-object read tools in that skill
Object-Centered Investigation → Act (drill-down before you change anything)
Judgment: after triage points at a problem object, drill in with one correlated read before actuating — the bundle aggregates the object with its surrounding infrastructure and recent history so you (and the operator) see the full picture, not a guess. AIops is the conversational entry point, so triage → investigate → act stays in one conversation.
Estate-wide --> cross_vcenter_attention ("what needs attention now?" across every vCenter). One vCenter configured → skip to cluster_health_summary
Drill into the flagged object (offer the level; skip the question when unambiguous):
a VM --> vm_investigation_bundle → state, host it runs on, cluster context, backing datastores, snapshots, alarms & recent changes, performance signals, correlated event timeline
a host --> host_investigation_bundle; a datastore --> datastore_investigation_bundle
Then act on the evidence --> e.g. bundle shows a wedged VM on a hot host → vm_migrate; a full datastore → vm_delete_snapshot on the sprawl the bundle surfaced. Follow the investigation protocol before any destructive action
Widen the window with hours=72; render an offline snapshot with --html (drill-down sections collapse natively, nothing uploaded)
If the object name is unknown --> the bundle returns a teaching error naming how to list objects; get the exact name and retry. If vmware-monitor is not installed --> these delegated tools are unavailable
Deploy a Lab Environment
Pre-flight (judgment, not blind sequence):
Free space: target datastore must have ≥ OVA size × 2 (delta files + thin-provision overhead). If multiple datastores qualify, prefer one with lowest current IOPS pressure (cross-check vmware-aria if available).
Name hygiene: prefix with date or owner (lab-2026-04-30-alice) so the TTL cleanup audit trail is meaningful.
TTL: always set. 480 min for a single test session, 7200 min for a week-long sandbox. Never deploy a "lab" VM without a TTL — that is how datastores fill up at 3 AM.
Snapshot timing: take the baseline after provisioning succeeds, not before — a pre-provision snapshot is just an empty checkpoint.
Decision rule: count > 10 → use linked clones (deploy linked-clone); seconds vs minutes per clone, ~100× less storage. Tradeoff: linked clones depend on source snapshot — deleting the snapshot breaks all children.
Network exhaustion: each clone gets a unique MAC from the vSphere pool; if you batch > 200, verify pool capacity in advance.
TTL: every clone must have one. Use the plan's metadata to track ownership.
Steps:
vm_create_plan with clone + reconfigure + set-ttl steps grouped per VM (atomic per clone)
Review the plan with the user — surface count, datastore, irreversible warnings
vm_apply_plan — stops on first failure (intentional, do not auto-resume)
On failure: vm_rollback_plan → reverses completed clones; manually verify rollback before retrying
Migrate VM to Another Host
Pre-flight (ALL must pass before issuing migrate):
CPU compatibility: target host CPU family must match source, OR cluster must be in EVC mode. Live migration across mismatched CPUs fails mid-flight and may leave the VM stunned.
Network parity: every portgroup the VM uses must exist on the target host's vSwitch with the same VLAN. Missing portgroup → vNICs disconnected post-migration.
Storage visibility: target host must see all of the VM's datastores; otherwise this is a Storage vMotion, not a host migration — different (slower) operation.
Affinity rules: if the VM is pinned to source by a DRS host-affinity rule, migration silently violates intent. Check cluster info first.
Hardware passthrough: VMs with PCI passthrough (GPU, USB) cannot live-migrate — schedule a cold migration window.
Steps:
Verify VM state and current host via vmware-monitor vm info <name>
Verify target host: same cluster, EVC compatible, has required networks/datastores
vmware-aiops vm migrate <name> --to-host <target> — wait for task completion, do not assume success on return
Post-check: vm info confirms new host AND power state unchanged AND vNICs connected
cluster_health_summary (delegates to vmware-monitor)
Read
Object Investigation (4)
vm_investigation_bundle, host_investigation_bundle, datastore_investigation_bundle, cross_vcenter_attention (all delegate to vmware-monitor)
Read
List envelope: the read list tools — browse_datastore, list_vcenter_alarms, vm_list_plans, vm_list_snapshots, vm_list_ttl — return {items, returned, limit, total, truncated, hint} rather than a bare array. Read the rows from items and check truncated before concluding a listing is complete; empty items with truncated: false means checked-and-none, not a failure. The write batch_* tools keep their bare list (complete by construction). Rationale, total semantics, error shape: references/capabilities.md.
Read/write split: 18 tools are read-only (per [READ] docstring marker), 42 modify state. All write tools require explicit parameters and are audit-logged. Destructive operations (vm_delete, vm_revert_snapshot, vm_delete_snapshot, vm_set_ttl (schedules an unattended auto-delete), force power-off, cluster delete/remove-host, alarm reset, remove_host_vmk, delete_drs_rule) require double confirmation at the CLI layer and support --dry-run.
Network write gating: create_dvs_portgroup, add_host_vmk, and set_vmk_service are preview/confirm-gated — confirm=False (default) returns the exact spec that would be applied without writing. remove_host_vmk is fail-closed: it refuses when the vmk is selected for a host service (management/vMotion/vSAN), lives on a non-default netstack (NSX TEPs, dedicated vMotion stacks), carries a default gateway route, or when any of that cannot be verified — pass force_unprotected=True to override the non-absolute protections. The host's only management-enabled vmk is never removable (no override). set_vmk_service is fail-closed too: it refuses both directions when the host's service map is unreadable, and refuses (no override) to untag management from the host's only management-enabled vmk — the call rides the interface it would untag.
DRS rule gating: set_drs_rule_enabled, create_drs_rule, delete_drs_rule are preview/confirm-gated and idempotent (matching state returns a no-write noop). create_drs_rule handles VM-VM affinity/anti-affinity only (≥2 distinct VMs, all cluster members); VM-Host rules are read via list_drs_rules but managed in the vSphere UI. delete_drs_rulerefuses non-VM-VM rules (they can carry licensing/compliance placement constraints) and records the full rule definition in both preview and result so a mistaken delete can be recreated from the audit trail.
Alarm reset blast radius: vSphere has no per-alarm clear API. reset_vcenter_alarm uses AlarmManager.ClearTriggeredAlarms, which clears all triggered alarms matching the named alarm's entity type (host/VM/all) and current status (red/yellow) — not just the one named. The response's scope field states exactly what was cleared. The named alarm is looked up first, so a typo fails fast without clearing anything.

Troubleshooting
"VM not found" error
VM names are case-sensitive in vSphere. Use exact name from vmware-monitor inventory vms.
Guest exec returns empty output
Use vm_guest_exec_output instead of vm_guest_exec — it auto-captures stdout/stderr. Basic vm_guest_exec only returns exit code.
Deploy OVA times out
Large OVA files (>10GB) may exceed the default 120s timeout. The upload happens via HTTP NFC lease — ensure network between the machine running vmware-aiops and ESXi is stable.
Snapshot delete is slow / "still running after Ns"
Deleting an old or large snapshot consolidates its delta disk into the parent — the slowest write
operation, often several minutes. vm snapshot-delete waits up to 30 min by default; if it still
returns a "still running, NOT failed" message with a task id, the delete did not fail — poll it with
vm task-status <task-id>. Do not re-issue the delete or hand-roll polling. For very large snapshots,
prefer vm snapshot-delete <name> --name <snap> --no-wait to get the task id immediately and poll.
Plan apply fails mid-way
Run vmware-aiops plan list to see failed plan status. Ask user if they want to rollback with vm_rollback_plan. Irreversible steps (delete_vm) are skipped during rollback.
Connection refused / SSL error
Verify target is reachable: vmware-aiops doctor
For self-signed certs: set disableSslCertValidation: true in config.yaml (lab environments only)
