virtualization-operations skillA
virtualization-operations is agent-read markdown (skill) from cbrock84/headcount: 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..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns 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@git:20260916.e72e404mdr add cbrock84/headcount/virtualization-operations@sha256:bf659a40dae9437bPin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
