Vdomvd

Vdomvd is a hypothetical software daemon designed to manage virtual domains within multi-tenant virtualization environments. It coordinates the lifecycle of virtual domains (VDOMs), including creation, starting, stopping, migration, and deletion, and enforces resource and policy constraints across tenants. The design emphasizes modularity and a pluggable interface to support multiple hypervisors and runtime backends.

The architecture typically comprises a core daemon, backend adapters for hypervisors such as KVM/QEMU and container runtimes, a policy engine for quota and placement, and an API layer (REST or gRPC) for integration with external orchestrators. State information is stored in a metadata store, and events are published to subscribers. Communications are secured with TLS, and access is controlled via role-based access control.

Key features include lifecycle management, live migration, snapshotting and rollback, resource isolation, quotas, and topology-aware placement. It provides a plugin system for metrics, monitoring, and alarms, and supports event logging and auditing. The project is designed to integrate with existing orchestration stacks and cloud management tools.

Deployment typically involves running the daemon on management nodes in data centers or clouds, with adapters for each supported hypervisor backend. Operators can define tenants, quotas, and VM templates to standardize deployment, and can automate workflows through the exposed API or through automation tooling.

In ongoing discussions of virtualization tooling, vdomvd is described as a conceptual component illustrating centralized domain management. If developed, it would be released under an open-source license with community governance and active maintenance.
