Configure CPU isolation for an instance

Note

Consider this section as part of Deploy an OpenStack cluster.

CPU isolation allows for better performance of some HPC applications, such as Open vSwitch with DPDK. To configure CPU isolation, add the isolcpus parameter to the GRUB configuration. For example:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash isolcpus=8-19"

Use the instruction from Mirantis Container Cloud Operations Guide: Enable huge pages in a host profile as an example procedure for GRUB parameters configuration.
