Phase I: Bringing the lab online

Estimated finish date: [DONE]
  • [DONE] Installing 2 nfs storage servers and setting up data mirroring using DRDB,and network bonding between them.
  • [DONE] Setting up the firewall rules to allow maintainance and external access (managed by DC team at Red Hat)
  • [DONE] Installing all hypervisors running fedora 19 (to allow nested virtualization)
  • [DONE] Set up networking for all hosts, including bonding and switch configuration (done by local network team at Red Hat)
  • [DONE] Setting up DNS for all servers, using ovirt.org domain.
  • [DONE] Installing ovirt hosted engine 3.4.Z and running on multiple hypervisors for fail-safe if one hypervisor is down
  • [DONE] Add all hypervisors to the hosted engine
  • [DONE] Add the nfs storage domain to hosted engine
  • [DONE] Create 2 DataCenters: Jenkins & Production (see diagram)
  • [DONE] Setting up DHCP, DNS, PXE via foreman-proxy to allow easy vm spawn and installation of operating systems.
  • [DONE] Test connectivity to other ovirt resources (rackspace, alterway)
  • [DONE] Add all bare-metal servers to foreman/puppet and ensure all authorized infra memebers have ssh access.
  • [DONE] Enure lab layout is documented and updated (including backup of network,fw configuration). Docs Infra/Phoenix_Lab_Overview

Lab Layout

Phase II: Setting up Jenkins DC

Estimated finish date: [DONE]
  • [DONE] Setting up a jenkins DC with 5 hypervisors
  • [DONE] Installing jenkins slaves with fedora/centos and starting testing jenkins jobs on them
  • [DONE] Installing nested hosts running feodra/centos and testing automation on them (probably in a different cluster)

Phase III: Decommision RACKSPACE

Estimated finish date: [DONE]
  • After verifying the new jenkins DC is capabale of running all our jenkins needs for the time being, remove all rackspace vms and stop the contract.

Phase IV: Start migration of production servers to production DC

Estimated finish date: TBD
  • Migrate production vms from alterway (gradually)
  • Migrate all services from resources.ovirt.org
  • Migrate jenkins server from alterway02 baremetal into production VM.
  • Add the alterway bare metal servers as hypervisors (dc/cluster is TBD)
  • Optional: migrate gerrit server from amazon into production DC
