virtualization-operations SKILL.md skillA
virtualization-operations from cbrock84/headcount is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Runs the hypervisor layer beneath the servers — host capacity and consolidation ratios, VM sprawl, snapshot discipline, resilience and live migration, and licensing that counts cores rather than instances. Use this to size or expand a cluster, work out why VMs are slow when the hosts look idle, clean up sprawl, set snapshot and template policy, or decide what stays virtualized and what moves to cloud.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Virtualization operations Virtualization is the layer most infrastructure problems actually live in, and the one most monitoring is blind to. A guest reports healthy CPU while contending for a core it never gets. The usual failure is diagnosing upward — into the application — when the constraint is a host two layers below. ## Consolidation ratio is a decision, not a result Every cluster has a ratio of virtual resources to physical ones, and most organizations discover theirs rather than choosing it. Overcommitting memory and CPU is normal and correct; the question is how far, and what happens at peak rather than average. Two numbers worth knowing at all times: what the cluster runs at now, and what it runs at when one host is gone. If losing a single host takes you past capacity, you have a cluster that survives hardware failure on paper and not in practice. Size for N-1 and keep the spare capacity visible in the budget, or the first thing cut is the headroom that makes the design work. Memory is usually the real ceiling, not CPU. Cores oversubscribe gracefully; RAM does not. ## Sprawl is a lifecycle problem wearing an infrastructure costume …

How to install
mdr add cbrock84/headcount/virtualization-operations@sha256:bf659a40dae9437bThe line at the top of this page pins the label git:20260916.e72e404, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
