Kevaso Concepts
Silo
A silo is the unit Kevaso runs: one stateful machine, either a microVM or a container. Silos are never replaced by copies; Kevaso enforces their desired state in place. A silo lives on one host.
Its runtime picks the implementation:
| Family | Runtimes |
|---|---|
| microVM | cloud-hypervisor, openshell |
| container | docker, podman, openshell-container |
Operators choose which runtimes each worker offers. microVM runtimes need KVM.
Host
A host is a machine you bring, plus an SSH key or initial root password. kvoadm sets it up once
over SSH; it never creates machines itself. Any modern Linux distribution with systemd (and KVM, for
microVMs) works.
Components
A host runs the components you install on it, and nothing is hidden:
- control-plane:
kvoadm initinstalls it. A host with it is a system node. - worker:
kvoadm host install <host> workeradds it. A host with it is a worker node.
Namespaces
Namespaces span hosts. Silos deny traffic from each other by default, even in the same namespace.
