StackBuffet and GUTS- the missing puzzle pieces in an

OpenStack private cloud

Dr Shunde Zhang, Senior Developer

StackBuffet: CI-as-a-Service

● CI-as-a-Service○ Local patches○ Distros are rigid○ Local CI too expensive/hard

Overview

● Build RPM/DEB packages from your source code● Test packages● Built-in repository (YUM or APT)● Multi-OS support (CentOS and Ubuntu)● Profiles

○ Virtualenv○ system lib (/usr/lib)○ docker image (future)

GUTS: OpenStack Migration Service

“A workload migration engine designed to

automatically move workloads and virtual machines

between two virtualization/cloud platforms”

Overview

● Migrate VMs off your traditional virtualization platform onto OpenStack

● Migrate VMs between two OpenStack clouds○ in two geographically distributed datacenters○ during an upgrade

● Migrate VMs between two virtualization platforms/clouds○ if they are both supported by GUTS

Use Cases

● guts-api service○ Accepts and responds to end user migration API calls.○ Enforces some policies and initiates most orchestration activities, such as

starting migration processes.● guts-scheduler service

○ Takes a migration request from the queue and determines on which migration service host it runs.

○ Selects a migration node based on conversion space available on migration nodes.

● guts-migration service○ A workers daemon that creates and manages migration processes of

computing instances.

Features● Pluggable and distributed architecture.● Provides virtual machine, storage and network migrations.● Converts disk image formats based on hypervisor types.● Installs / uninstalls cloud specific tools like VMWare-Tools

and virtio tools.● Optimizes migration process by scheduling migration

operation to appropriate migration node.● Currently Guts supports VMWare, OpenStack as source

hypervisors and OpenStack as destination hypervisor.

Guts-Dashboard

● Horizon plugin extension which provides UI for guts workflow.
