With the Grizzly release of OpenStack comes many new features for Hyper-V and Windows platforms. This was the work that was done for the Grizzly the release, and get an early preview before the Havana Summit in Portland. Come and see Grizzly running on Hyper-V and supporting new features such as: Quantum Quantum Agent for Hyper-V VLAN and Routing Support Cinder Windows as a Storage Server Nova Resize/Cold Migration HTML5 Canvas/RDP Gateway Cloudinit functionality for Windows guests.

3. Hyper-V Compute
OpenStack can utilize the key features of Windows Server
2012 Virtualization Platform

4. OpenStack Grizzly Hyper-V
 Nova Grizzly Compute for Hyper-V
 Quantum Agent for Hyper-V
 Cloudinit functionality for Windows Workloads
 Cinder for Windows Storage Server
 FreeRDP Gateway
 Puppet Windows PE Provisioning.

5. Architecture 1

6. Hyper-V driver
WMI
 Currently V1 namespace (root/virtualization)
 V2 namespace used for live migration
 Complete migration to V2 for Havana
Grizzly OS support
 Windows Server / Hyper-V 2008 R2, 2012
 Windows 8 supported for development
Havana OS Support
 New features will target 2012 and above only

7. Hyper-V driver disks
 Copy on write (CoW) implemented with differencing disks
 Reconnected and merged during snapshots
 Reconnected and merged on resize
 Not necessary for VHDX (Havana)

8. Architecture 2

9. Quantum
 Network connectivity as a service
 Plugin based architecture
 Official plugins:
 Open vSwitch
 Cisco UCS/Nexus
 Linux bridge
 Nicira NVP
 Ryu OpenFlow
 NEC OpenFlow
 Big Switch OpenFlow
 Hyper-V

10. Hyper-V plugin
Quantum plugin
 Runs in quantum-server
 Database based configuration
 Networks, subnets, ports
Quantum agent
 Runs on any compute node
 Supports:
 Local (private vSwitch)
 Flat
 VLAN
 NVGRE (Havana)
 Communicates with plugin via AMQP
L3 support:
 Using the Linux L3 and DHCP plugins

11. Hyper-V plugin
Nova compute driver
 Creates the vNics (one per network)
 Does not connect them
Quantum agent
 Creates the vswitch ports
 Sets the VLAN ID and proper vswitch mode
 For NVGRE creates instances of:
 MSFT_NetVirtualizationLookupRecordSettingData
 etc

12. Horizon
 Main UI
 Implemented in Python with Django
 Typically deployed on Apache with mod_wsgi
 Includes console access
 Currently only VNC
 RDP to be added for Havana

13. Hyper-V console
Hyper-V provides console access via RDP, but using additional settings
compared to a standard RDP connection
 Port: 2179 (instead of 3389)
 PCB: preconnection blob, contains the VM ID (a GUID)
 Passing the PCB is possible using:
 The Microsoft remote Desktop ActiveX control
 FreeRDP

14. FreeRDP
Our solution is based on FreeRDP
 Fork is going to be merged with main repository
Open Source RDP client (Apache 2)
 https://github.com/FreeRDP/FreeRDP
Works on Linux, Windows and Mac OS X
Web gateway based on FreeRDP-WebConnect
 https://github.com/FreeRDP/FreeRDP-WebConnect

15. Web Gateway
Client
 HTML5
 Works on any modern browser
 Web sockets for data transfer
 Canvas for painting
 Can be embedded in any web site
Server proxy
 (wsgate) written in C++
 Currently working on Linux
 can work on Windows

16. Dashboard integration
Decoupling from VNC
 Create plugin that embed the canvas in the Dashboard
Authentication layer
 Keystone token validation
Logic for retrieving VM id from OpenStack instance ID
 Ask Nova about the instance details, in particular the Hyper-V host running it
 Get cached hypervisor credentials from keyring or similar
 Query the Hyper-V host about the RDP console port (2179 by default)
 Retrieve the VM id from the host given the instance name
 Perform connection via wsgate

17. Instance initialization
Guests require cloud specific customization on startup, e.g.:
 Hostname
 SSH keys
 Users / groups, password management
 Partition resize
 Static network configuration
 Custom scripts
 On Windows: Powershell, cmd.exe, bash

18. Metadata access
 Metadata needs to be provided to the guest:
 Metadata API, accessed via 169.254.169.254
 Openstack or EC2 format
 ConfigDriveV2

19. Cloud-Init
Project provided by Canonical
 Currently Linux specific
 GPL
 Windows Cloud-Init (cloudbase-init)
 Written in Python
 Apache 2
 Very easy to install
 Supports any Hypervisor

20. Windows Cloud-Init

21. Windows images
 Create VM
 Install OS
 Manual or unattended setup
 On KVM include VirtIO drivers
 Keep partition sizes as small as possible
 Apply SP / updates
 Install Windows Cloud-Init
 Sysprep
 Shutdown
 Copy instance to Glance

22. Nova Compute Installer

23. Nova Compute Installer
 Provides a very simple way to install OpenStack on a Windows
compute node
 Can be executed fully unattended
 Installs a complete Python environment
 Generates Nova and Quantum configuration files
 Based on user input:
 Creates external virtual switches
 Installs the Quantum Hyper-V agent
 Enables live migration
 Enables the iScsi initiator service

24. Puppet Manifests for Windows/Linux
Provisioning
 Puppet manifests for complete windows pxe deployment
 Compute pxe infrastructure to programmatically boot all openly
available linux distributions
 Integration from wireline provisioning through configuration
management.

25. OpenStack/Hyper-V Demo
