Chapter 6 Installing the Cisco CSR 1000V in KVM Environments

Increasing Performance on KVM Configurations

Note When configuring CPU pinning, carefully consider the CPU topology of the host server. If using

a Cisco CSR 1000V configured with multiple cores, do not configure CPU pinning across

multiple sockets.

• Enabling the vhost-net Driver

To improve performance in KVM environments, Cisco recommends that you enable the LINUX

vhost-net driver. Make sure the vhost-net driver is loaded by entering the following command on the

KVM host:

modprobe vhost-net

For more information, see the KVM documentation.

Note The vhost-net setting is enabled by default on KVM Ubuntu installations. If using Red Hat

Enterprise Linux, you must specify which devices will use the XML definition file.
