Virtual NUMA (vNUMA) is a virtualization mechanism used to present or manage virtual-machine or cluster resources.
Simple definition
Virtual NUMA (vNUMA) is a virtualization mechanism used to present or manage virtual-machine or cluster resources. It belongs to the Virtualisation / Conteneurs vocabulary.
What is it used for?
Its main purpose is to optimize execution, compatibility, or availability of virtualized workloads.
How does it work?
the hypervisor arbitrates physical resources and exposes suitable abstractions or policies to VMs.
Key points
- Scope: A virtualization mechanism used to present or manage virtual-machine or cluster resources.
- Operational goal: Optimize execution, compatibility, or availability of virtualized workloads.
- Mechanism: the hypervisor arbitrates physical resources and exposes suitable abstractions or policies to VMs.
Points to watch
Overcommitment and compatibility changes should be measured to avoid contention or downtime.
In short
Virtual NUMA (vNUMA) is a Virtualisation / Conteneurs concept to know when you need to optimize execution, compatibility, or availability of virtualized workloads.
