Hybrid service chaining across multiple Hypervisors
OpenContrail supports multiple types of hypervisors and containers. These can spawn simple tenant VMs and also more complex service instances implementing a Virtualized Network Function (NFV).
This video demonstrates a service chain composed of two service instances. One is running on a KVM host, and the other on an ESXi host.
This hybrid service chain enables value-added services for tenant VMs which are also spread across KVM and ESXi hypervisors.
Also, check out how to introduce secure multi-tenancy to VMware/vCenter clusters via open source network virtualization.
