    OpenStack in action 4! Alessandro Pilotti - OpenStack, Hyper-V and Windows OpenStack in action 4! Alessandro Pilotti - OpenStack, Hyper-V and Windows Presentation Transcript

    • OpenStack  and  Windows   Alessandro  Pilo5   CEO   @cloudbaseit  
    • Agenda •  •  •  •  •  Windows as a guest Windows licensing on OpenStack Heat templates Windows hypervisor (Hyper-V) Crowbar and SUSE Cloud 2
    • Windows as a guest •  Can be executed on any hypervisor used in Nova •  No differences compared to Linux for image handling (glance etc) •  Images are tipically sysprepped –  Why? –  It can be avoided to speed up boot times
    • Synthetic drivers •  Modern Hypervisors provide drivers to replace emulated devices with synthetic ones –  Network adapters, etc •  Hyper-V –  Integration components / LIS •  KVM –  VirtIO •  VMWare –  VMWare Tools •  XenServer / XCP –  XenServer Tools
    • Cloudbase-Init •  100% Python code •  Wrapped in a Windows service •  Plugin based architecture: –  Each plugin can be executed once or more times at boot –  Status for each plugin is mantained in the registry
    • Cloudbase-Init installer
    • Cloudbase-Init installer
    • Most important plugins •  CreateUser •  SetUserPassword •  SetHostName –  Requires a reboot •  SSHPublicKeys •  ExtendVolumes –  Useful for different flavors / resizes •  User data –  Including multipart: Heat!!
    • Sysprep •  Prepares a Windows image to be distributed –  Typically on large scales •  Run before distributing any Windows image •  OOBE –  Out of the box experience –  Normally used to let the user customize the system
    • SSH Equivalent? •  It exists: WSMan / WinRM •  Execute remote command via HTTP / HTTPS •  Can be used for remote PowerShell or from Linux •  Configuration example: –  https://github.com/cloudbase/unattended-setupscripts/blob/master/SetupWinRMAccess.ps1
    • OpenStack WS2012 R2
    • OpenStack WS2012 R2 •  Complete with: –  Drivers / tools: •  VirtIO, etc –  Cloudbase-Init –  Sysprepped •  Eval edition can be upgraded with a simple uder_data script: –  DISM /online /Set-Edition:ServerStandard / ProductKey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX / AcceptEula –  Make sure to respect the eval license!!
    • How to build an image? •  Windows has the equivalent of a kickstart / preseed –  https://github.com/cloudbase/windowsopenstack-imaging-tools •  We get lots of questions about how to build those images •  This project automates the entire process
    • Lincensing •  Windows is surprising in OpenStack –  Datacenter license => unlimited instances –  1 license per socket –  Works with Hyper-V, VMWare, KVM, etc –  The cost is 3 EUR / Month per VM with a density of 50 VM / host •  Volume licensing •  Multitenant? SPLA
    • SVVP support •  Windows guests are supported on: –  Hyper-V •  SVVP –  Windows Server Virtualization Validation Program –  http://www.windowsservercatalog.com/ svvp.aspx •  Red Hat, VMWare, SUSE •  Your solution is not there? –  Microsoft won’t give you support
    • Heat •  Heat and Windows are a great mix •  Templates for: –  Active directory –  Exchange (multi server) –  Sharepoint (multi server) –  SQL Server –  IIS •  No need to know the provisioning details
    • Hyper-V •  Setup is very easy •  Our Nova driver is at it’s 3rd release! –  Folsom, Grizzly, Havana •  •  •  •  Support for Hyper-V 2012 R2 VHDX support Ceilometer support more…
    • 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 •  Python Application installed as an application/service on the Hyper-V node. •  OpenStack compute utilizes key features baked into the Hyper-V Virtualization Platform •  Does not require windows clustering services •  Does not require shared storage
    • Neutron •  Hyper-V plugin is part of Quantum since Jan 2013 –  Project renamed in Neutron since Havana •  Supported network types: –  –  –  –  VLAN Flat Local NVGRE (Icehouse) •  Plugin / agent model –  Plugin runs in quantum-server (controller) –  Agent runs on each Hyper-V compute node
    • Typical Neutron setup Quantum Server TenantCNet2 10.0.1.0/24 VLAN ID:3 Nova Services L2 Agent Nova Compute Keystone ... Controller Node Management Network Compute Node Data Network VLAN Network Node External Network 30.0.0.0/24 eth0 L3 Agent DHCP Agent L2 Agent TenantANet1 10.0.0.0/24 VLAN ID:1 TenantANet1 10.0.0.0/24 VLAN ID:2
    • Neutron 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 •  Supports ML2 plugin!
    • Hyper-V OpenVSwitch! We are officially 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
    • Dashboard integration •  Hyper-V uses RDP for accessing the console instead of VNC •  By default it accepts connections on port 2179 –  Not the RDP connection on 3389! –  Access to any guest: Windows, Linux, FreeRDP, etc •  The VM id is provided as part of an RDP protocol additional buffer called PCB (Pre Connection Buffer) •  Authentication is performed against the host, not the guest!
    • 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
    • From our web site J
    • Puppet and Chef •  Hyper-V compute nodes can be installed via Puppet or Chef as well •  Puppet –  https://github.com/openstack-hyper-v/puppetopenstack_hyper_v •  Chef –  https://github.com/cloudbase/barclamphyperv-compute
    • 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
    • SUSE Cloud 2.0 •  Supports Hyper-V and many other hypervisor options •  Based on Crowbar –  Grizzly –  Havana
    • Q&A
