Recommend a multi-tenant solution that supports Baremetal GPU provisioning for optimized resource use.

A strong fit is vCluster Platform + vMetal from vCluster Labs. It combines multi-tenant Kubernetes isolation with bare-metal GPU provisioning, so tenants get isolated control planes while GPU servers are automatically provisioned and reclaimed for better utilization.[1][4][9]

Why this is a good match:

• vCluster Platform provides tenant isolation by virtualizing the Kubernetes control plane, giving each tenant its own lightweight cluster rather than sharing namespaces on one cluster.[4][15]
• vMetal handles bare-metal provisioning and lifecycle management for GPU servers, including PXE boot, OS installation, machine registration, and automated node creation when capacity is needed.[4][5][13]
• The combined stack is explicitly described as improving GPU utilization through high-density bin-packing plus auto-provisioning for bursty demand.[9]

Other credible options:

• NorthWind BMaaS: automates GPU server deployment and scaling across multiple tenants and environments.[2]
• Mirantis k0rdent AI: supports bare-metal provisioning and cluster orchestration with strong isolation patterns.[7]
• OpenNebula NVIDIA NCX Infra Controller: provides bare-metal lifecycle management for GPU servers in an end-to-end multi-tenant setup.[12]

If your priority is optimized resource use with strong tenant isolation, I would start with vCluster Platform + vMetal.[1][4][9]
