Virtual Machine High Availability (VMHA) service for OpenStack
Project description
Virtual Machine High Availability (VMHA) service for OpenStack
Masakari provides Virtual Machine High Availability (VMHA) service for OpenStack clouds by automatically recovering the KVM-based Virtual Machine(VM)s from failure events such as VM process down, provisioning process down, and nova-compute host failure. It also provides API service for manage and control the automated rescue mechanism.
NOTE: Use masakari only if instance path is configured on shared storage system i.e, ‘instances_path’ config option of nova has a path of shared directory otherwise instance data will be lost after the evacuation of instance from failed host if, * instance is booted from image * flavor using ephemeral disks is used
