Production Ready OpenStack - Recipes for Successful Environments

Overview of this book

OpenStack is the most popular open source cloud platform used by organizations building internal private clouds and by public cloud providers. OpenStack is designed in a fully distributed architecture to provide Infrastructure as a Service, allowing us to maintain a massively scalable cloud infrastructure. OpenStack is developed by a vibrant community of open source developers who come from the largest software companies in the world. The book provides a comprehensive and practical guide to the multiple uses cases and configurations that OpenStack supports. This book simplifies the learning process by guiding you through how to install OpenStack in a single controller configuration. The book goes deeper into deploying OpenStack in a highly available configuration. You'll then configure Keystone Identity Services using LDAP, Active Directory, or the MySQL identity provider and configure a caching layer and SSL. After that, you will configure storage back-end providers for Glance and Cinder, which will include Ceph, NFS, Swift, and local storage. Then you will configure the Neutron networking service with provider network VLANs, and tenant network VXLAN and GRE. Also, you will configure Nova's Hypervisor with KVM, and QEMU emulation, and you will configure Nova's scheduler filters and weights. Finally, you will configure Horizon to use Apache HTTPD and SSL, and you will customize the dashboard's appearance.

Configuring Nova Hypervisors


The nodes running virtual machine instances are commonly referred to as Compute nodes. Nova Compute nodes are running the nova-compute service, which manages the hypervisor it runs on via a hypervisor driver. A Nova-compute service passes commands to the local hypervisor via the driver to spawn or destroy virtual machine instances. The default and most commonly selected hypervisor with OpenStack is KVM; it requires virtualization hardware support by a CPU. CPUs with native support for KVM can be identified by VT-d (vmx flag) with Intel CPUs and AMD-v (svm flag) with AMD CPUs.

Note

All supported hypervisors are listed in the OpenStack Wiki page https://wiki.openstack.org/wiki/HypervisorSupportMatrix.
