OpenStack & Hyper-V

Cloudbase Solutions• Company started in Italy as .Net /

Linux interop dev and consulting• Branch started in Timisoara in 2012 to

hire devs and provide colocation services

• Started using OpenStack for the internal IDC

• Added Hyper-V support• OpenStack business exploded

Agenda • OpenStack + Hyper-V integration• FreeRDP HTML5 dashboard• OpenVSwitch on Windows• Cloudbase-Init• Windows Server 2012 Eval Image• Crowbar integration• Cross Cloud Migration • Havana plans

Hyper-V 2012 availability• FREE edition– Full Hypervisor– Minimum OS support

• Minimum impact on security updates, etc• Windows Server 2012– Just enable the related role

• Windows 8– For workstation / testing / development

usage

Hyper-V / Windows Openstack components• Nova Compute driver• Quantum plugin• Cinder Volume driver• Windows Cloud-Init• Ceilometer Agent (Havana)

Hyper-V Nova Compute• Supported features (anything missing? )

– Launch / reboot / terminate– Resize– Pause / unpause– Suspend / resume– Attach / detach volume– Live migration– Snapshot– Guest / host info– Glance integration– Config Drive– Rescue (Havana)– RDP console (instead of VNC)

• Deprecated Nova network is not supported beyond “flat” networking– All Hyper-V networking features are part of Quantum

Quantum• Hyper-V plugin is part of Quantum

since Jan 2013• Supported network types:– VLAN– Flat– Local– NVGRE (Havana)

• Plugin / agent model– Plugin runs in quantum-server (controller)– Agent runs on each Hyper-V compute

node

Quantum OVS interop• Quantum plugin / agent AMQP RPC protocol

is compatible with OpenVSwitch!!• You can use the OVS plugin with Hyper-

V agents (or vice versa)– Limited to compatible L2 protocols: Flat / VLAN

• You can use the L3 and DHCP agents with the Hyper-V plugin– Using the OVS L2 agent on the networking nodes

• Great for interoperability (e.g. KVM + Hyper-V)

Hyper-V OpenVSwitch!

We officially started porting OpenVSwitch to Windows!!

Why OpenVSwitch?• De facto standard for SDN• Great interoperability– Hyper-V / KVM / etc

• OpenFlow• Tunnelling– VXLAN– GRE

• Quantum OVS plugin– No need for a different one

OpenVSwitch porting• Porting Posix calls to Windows API• Same CLI as on Linux• Open Source• Windows kernel drivers– NDIS Hyper-V extensions

• VXLAN, GRE– Best performance

• Support for Hyper-V 2012 and above

OpenVSwitch

Windows Kernel drivers

Typical Quantum setup

VLAN drivers issues• BEWARE: Some Windows NIC drivers disable VLAN

access by default!

• HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e972-e325-11ce-bfc1-08002be10318}

• Look in all the child keys xxxx, e.g. 0001, 0002 etc for a value "VLanFiltering". Make sure that if present it's set to 0. 

• In case of changes, reboot the server or restart the corresponding adapters.

FreeRDP• FreeRDP is an amazing RDP open source

client.– Apache 2 license– Multiplatform

• Linux• Mac OS X• Windows

• It provides support for the PCB parameter required by Hyper-V

• We are using it as a standalone client on the free Hyper-V server and on Linux, Mac OS X

FreeRDP-WebConnect• An HTML5 RDP client based on canvas

and websockets– Similar to NoVNC

• Uses a C++ demon (wsgate) to handle websocket connections and connect to the RDP server– Better performance compared to the

Python proxy used by NoVNC• We provided support for Hyper-V

Nova Compute Installer • Independent Python environment to avoid

conflicts with existing applications

• Installs and registers all the required dependencies

• Generates dynamically a nova.conf file based on the parameters provided by the user

Nova Compute Installer • Creates a new Hyper-V external switch if

required

• Registers nova-compute as a service and starts it

• Registers quantum-hyperv-agent as a service and starts it (optional)

• Enables the Microsoft iSCSI Initiator service (optional)

Unattended mode• Can be installed in fully unattended mode, great for:

– Chef, Puppet, Group Policies…• msiexec /i HyperVNovaCompute.msi /qn /l*v log.txt

Nova Compute Installer

From our web site

Windows Cloud-Init• Cloudbase-init (aka Windows Cloud-

Init)– Similar to the Linux cloud-init– License: Apache 2

• Porting Cloud-Init to Linux was not possible– It requires some major refactoring

• Supported data sources:– OpenStack HTTP metadata– ConfigDrive V2– EC2 HTTP metadata (contributed by

Mirantis)

Windows Cloud-Init• Plugin based architecture• Supported plugins:– SetHostNamePlugin– CreateUserPlugin– NetworkConfigPlugin– SetUserSSHPublicKeysPlugin– UserDataPlugin– ResizeFSPlugin

Userdata format• Windows Batch• Powershell• Bash• Multi-part (Havana)– Heat support

Password generation• New Grizzly feature1. Password is randomly generated

– Can be forced to the value injected by Nova2. Password in encrypted with the SSH public

key3. Password is POSTed to the metadata

service4. Password can be retrieved by the client

and decrypted with the SSH private key– nova get-password vm1 .ssh/id_rsa

Windows Installer

Unattended mode• Like all our installers, it can be

executed in fully unattended mode:• msiexec /i CloudbaseInitSetup.msi

/qn /l*v log.txt NETWORKADAPTERNAME="Intel(R) PRO/1000 MT Network Connection"

OpenStack Windows Server 2012!!

OpenStack WS2012• WS 2012 Standard - Evaluation edition– Testing only!!

• Available for:– Hyper-V– KVM– XenServer / XCP

• www.cloudbase.it

OpenStack WS2012 • Complete with:

– Drivers / tools:• VirtIO / XenServer Tools

– Make sure to respect the eval license!!

Cinder Windows installer• Cinder includes a driver for Windows

Storage Server 2012• We created an installer that deploys a

complete Python environment with all the required dependencies

• Registers and starts cinder-volumes

• Key community contributor:– Pedro Navarro Perez (Tx! )

Crowbar• Big part of Dell’s cloud strategy• Bare-metal deployment• vendor independent• PXE booting– Sledgehammer image boots and gets

configuration• Provisioning via Crowbar web site• Barclams– Configuration– Chef recipes

Crowbar + HyperV

Cross Cloud migration• Vendor lock-in anybody? • Just a few clicks to migrate virtual

workloads to and from:– Amazon AWS– Azure– OpenStack

• Including RackSpace– VMWare vSphere– MS System Center

• Currently in beta

Havana!!• Planning for Havana now!

– More Quantum: NVGRE, security groups, etc– Ceilometer Hyper-V agent– Heat Windows Cloud-Init support – VHDX support – Ephemeral storage– Support for more image formats (e.g. AMI/ARI/AKI)– Nova rescue– Active Directory Keystone scalability– VDI support– Fibre channel– VM dynamic memory support– Cinder improvements…
