Masakari - Virtual Machines High Availability


Masakari provides Instances High Availability Service for OpenStack clouds by automatically recovering failed Instances. Currently, Masakari can recover KVM-based Virtual Machine(VM)s from failure events such as VM process down, provisioning process down, and nova-compute host failure. Masakari also provides an API service to manage and control the automated rescue mechanism.

Kolla deploys Masakari API, Masakari Engine and Masakari Instance Monitor containers which are the main Masakari components only if enable_masakari is set in /etc/kolla/globals.yml.

Connection URI to libvirtd

By default masakari-instancemonitor will connect to libvirt daemon using qemu+tcp:// connection URI to get events of KVM-based virtual machines.

The setting is overridable using custom config, put the content in /etc/kolla/config/masakari/masakari-monitors.conf.

connection_uri = "xen://{{ migration_interface_address | put_address_in_context('url') }}/system"
