Masakari
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
