7. Providers - Highlights
● OpenStack
○ cleanup SSL support
○ VM operations
● Microsoft System Center
○ delete VMs
● Containers
○ tons of UI updates (DanC)

Google Cloud Engine demo by Adam Grare

9. Appliance Core - Replication
Researching replacement for Rubyrep
● Rubyrep is not actively maintained
● Implemented in Ruby and SQL
● Relies on external daemon process and SQL triggers
● Performance suffers on slow networks with frequent data churn

10. Appliance Core - Replication
BDR - Bi-Directional Replication [*]
● Operates within the Postgres process as an extension
● Developed and maintained by Postgres contributors
● Integrated in ManageIQ as a POC
● Performance testing in-progress
[*] http://bdr-project.org/docs/0.9/index.html

11. Appliance Core - Replication
What BDR can do for us?
● Better performance
● High availability
● Administration from any region

12. Appliance Core
Workers
● Forked from main server process instead of spawned
● Faster worker startup
● Leverages copy-on-write for sharing memory in Ruby 2.0+
● Expect reduced worker memory once tuned
● Added smem package to appliance

13. Rest API (A. Bellotti)
● New primary collection for Instances
GET /api/instances
● Supporting the terminate action for instances
Target single Instance via POST /api/instances/:id or multiple Instances via POST /api/instances
○ Terminate Instance - Power->Terminate
POST /api/instances/:id
{
“action” : “terminate”
}

14. Rest API (A. Bellotti)
● Ability to filter string equality/inequality on virtual attributes.
This allows us to filter on categories by name:
GET /api/categories?filter[]=name=’value’
● Ability to retrieve user’s default language
This is needed by SSUI to know the user’s preferred language to set angular-gettext to the right
language:
GET /api
...
“settings” : {
“locale” : “en”
},
...

15. Rest API (A. Bellotti)
● Adding support for Dynamic Dialogs
This enhancement for the SSUI allows fields to be queried as the dialog is getting populated. This is
made available as a new refresh_dialog_fields action on the service template resource:
POST /api/service_catalogs/:id/service_templates/:st_id
{
“action” : “refresh_dialog_fields”,
“resource” : {
“dialog_fields” : {
“field1” : “value1”,
“field2” : “value2”,
“field3” : “value3”,
…
}
“fields” : [ “field1”, “field3”]
}

16. User Interface (D. Clarizio)
● PRs merged (123), bugs (55), enhancements (28), refactoring (28)
● New functionality
○ I18n
■ Mark translated strings in the UI
■ Gettext support added to JS source code
○ Converted toolbar images to font icons
○ Enabled font icon support in list views
○ Implemented Bootstrap switch
● Containers
○ Dashboard network trends
○ Container environment variables table
○ Search functionality for Container topology
○ Dashboard no data cards
○ Refresh option in Configuration dropdown

26. Automate
Simulate UI support for state machine retries
● Problem
○ When state machines are tested with Simulation there is no indication to the user that a
retry is needed.
○ State Attributes are not preserved between invocations.
● Features
○ Add “Retry” button to UI if the state machine requests a retry.
○ Preserves the state attributes so that it can be used in the next retry invocation.
○ The ae_state_retries can be reset from the Attribute/Value Pairs section of the UI.

28. Automate
● Support where method for service models (PR #6046)
vms = $evm.vmdb(:vm).where(:id => 2349, :vendor => "redhat")
=> [#<MiqAeServiceManageIQ_Providers_Redhat_InfraManager_Vm...
● find_by and find_by! also available
vm = $evm.vmdb(:vm).find_by(:id => 2349, :vendor => "redhat")
=> #<MiqAeServiceManageIQ_Providers_Redhat_InfraManager_Vm...
vm = $evm.vmdb(:vm).find_by!(:id => 2349, :vendor => "redhat")
=> #<MiqAeServiceManageIQ_Providers_Redhat_InfraManager_Vm...
Note: Automate will return an array or service model as a results of the query. This means you cannot chain the
methods together.
For example this work in Rails:
Vm.where(:id => 2349).where(:vendor => "redhat")
=> #<ActiveRecord::Relation [#<ManageIQ::Providers::Redhat...
The same thing will not work in automate:
vm = $evm.vmdb(:vm).where(:id => 2349).where(:vendor => "redhat")
NoMethodError: undefined method `where' for #<Array:0x007f9b22d23a38>

29. Automate
● Event Switchboard
○ Openstack events updated to trigger policy events
■ compute_instance_pause
■ compute_instance_unpause
■ compute_instance_resume
■ compute_instance_suspend
● Retirement
○ Removed tagging (Lifecycle/Retire_Full) and
“provisioned” check from “Remove from Provider”
state.

30. Ansible (G. McCullough)
● Modeling for Provider, Configuration
Manager, and Configured Systems
● Provider connection logic
● Support refresh of Configured Systems
● Ansible Tower Client gem
○ Credential validation
○ Supported resources
■ Hosts
■ JobTemplates
■ Adhoc commands

31. SmartState Analysis (R. Oliveri)
SSA for SCVMM providers.
● Supported:
○ Virtual hard disks residing on Hyper-V servers.
○ VHD, and newer VHDX disk formats.
○ Snapshotted disks.
○ Same filesystems as other providers.
● TODO:
○ Disks mounted from network datastores.
■ Multi-hop authentication issue.
○ Performance improvements.
