 ### RHEL/CentOS VM images
-The base RHEL or CentOS-based non-HPC VM images on the Marketplace can be configured for use on the SR-IOV enabled [RDMA capable VMs](sizes-hpc.md#rdma-capable-instances). Learn more about [enabling InfiniBand](enable-infiniband.md) and [setting up MPI](setup-mpi.md) on the VMs.
