INFRASTRUCTURE SIMULATION ENGINE

Chimera

One engine, many infrastructure personalities: integration-test migration, discovery, export, and automation software without provisioning the real vSphere, Nutanix, Hyper-V, AWS, or Azure platform.

How Chimera compares

• Chimera One engine, five personas — vSphere deepest (full govmomi session, ExportVm/HttpNfcLease, HTTP Range/206 resume), plus Nutanix, Hyper-V, AWS, and Azure as protocol surfaces.
• vcsim (govmomi's own vCenter simulator) Similar vSphere depth, from the same govmomi project — but vSphere-only.
• LocalStack AWS service emulation only — no vSphere, Nutanix, Hyper-V, or Azure coverage.
• WireMock / Testcontainers Generic HTTP mocking or real service containers — you hand-write the persona yourself.

(General characterizations as of writing — verify current features against each project's own docs.)

Chimera is Apache-2.0 licensed. It is a test and compatibility appliance — not VMware, Nutanix, Microsoft, Amazon, Red Hat, Proxmox, or cloud-vendor software — and it is not intended to host production workloads.

1. One engine, five infrastructure personas: vSphere (deepest), Nutanix Prism v3, Hyper-V WS-Man, AWS EC2/EBS, and Azure ARM. See Provider Architecture. ↩
2. vSphere is the only persona with a full Command Center dashboard today; Nutanix, Hyper-V, AWS, and Azure are protocol surfaces only, per the Provider Architecture status table. See Provider Architecture — Status today. ↩
3. The acceptance matrix runs 98 checks: 1-74 vSphere, 75-87 Nutanix/Hyper-V, 88-98 AWS/Azure. See the Test Matrix. ↩
4. The Command Center overview header tracks six live KPIs: total requests, error rate, active vSphere sessions, transferred response bytes, NFC/export starts, and average response latency. See Command Center UX. ↩
