Verified Scalability Guide for Cisco Nexus 1000V for KVM Release 5.2(1)SK3(1.1)
This document describes the verified configuration limits for Cisco Nexus 1000V for KVM software. The following is the change history for this document.
Introduction
Cisco Nexus 1000V for KVM is a distributed virtual switch that works with the Linux Kernel-based virtual machine (KVM) open source hypervisor. In addition, Cisco Nexus 1000V for KVM uses OpenStack as its cloud operating system that controls large pools of compute, storage, and networking resources throughout a datacenter.
The networking function of OpenStack is controlled and managed by a process called Neutron on the network controller. Neutron has been extended in a such a way that the Cisco Nexus 1000V for KVM can now provide the networking capabilities to the compute nodes and the virtual machines (VMs). As Neutron creates and configures its networks for its environment, this configuration is passed to the Cisco Nexus 1000V for KVM switch.
Using OpenStack, you create VM networks and subnets on the Cisco Nexus 1000V for KVM, by defining components such as the following:
Using the Cisco Nexus 1000V for KVM VSM, you create policy profiles (called port profiles on the VSM), which define port classification information, such as security settings (ACLs and so on).
When a VM is deployed, a port profile is dynamically created on the Cisco Nexus 1000V for KVM for each unique combination of port classification, VM network, and VM subnet. All other VMs deployed with the same policy to this network reuse this dynamic port profile.
NoteYou must consistently use OpenStack for all VM network and subnet configuration. If you use both OpenStack and the VSM to configure VM networks and subnets, the OpenStack and the VSM configurations can become out-of-sync and result in faulty or inoperable network deployments. For information about OpenStack, see the You must consistently use OpenStack for all VM network and subnet configuration. If you use both OpenStack and the VSM to configure VM networks and subnets, the OpenStack and the VSM configurations can become out-of-sync and result in faulty or inoperable network deployments. For information about OpenStack, see the Cisco Nexus 1000V for KVM Virtual Network Configuration Guide.
