Deploying SUSE Cloud in a Multi-Hypervisor Enterprise Environment
2 likes•784 views
This document discusses deploying OpenStack in a multi-hypervisor enterprise environment. It notes that enterprises currently have large investments in virtualization infrastructure like VMware, and outlines some of the challenges of introducing an open-source cloud platform. It then describes how OpenStack's drivers allow it to support multiple hypervisors like VMware and Hyper-V, providing a single control plane to manage workloads on different infrastructure. Limitations of the hypervisor drivers are also discussed.

Deploying SUSE Cloud in a Multi-Hypervisor Enterprise Environment
- 1. Deploying OpenStack In a Multi-Hypervisor Enterprise Environment Rick Ashford Senior Technical Specialist [email protected]
- 2. 2 21 Years of Adapting Open Source
- 4. 4 SUSE Cloud 3 Highlights • Based on OpenStack Havana ‒ Orchestration module (Heat) project for VM orchestration ‒ Telemetry module (Ceilometer) improves cloud measurement • New Features ‒ Full VMware support ‒ Improved networking and block storage adapter support ‒ Cisco Nexus, EMC, VMware NVP and others ‒ Updated Ceph packages ‒ SUSE Cloud 2 to SUSE Cloud 3 upgrade ‒ Manual addition of existing servers as cloud nodes • Platform for High Availability ‒ Delivered as update in March
- 6. 6 Enterprises Fear Change Cloud computingCloud computing represents arepresents a fundamental changefundamental change to IT processesto IT processes 6
- 7. 7 Enterprises Fear Change • Large investments have already been made in existing virtualization infrastructure • Investment in skilled employees • Training investment • Lack of familiarity with open-source hypervisors • Vast majority of VMware administrators are Windows users • Disaster-recovery infrastructure and procedures
- 8. What do Enterprises Need?
- 9. 9 Ideally it's all the same...
- 10. 10 What Do They Need? • No data center is homogeneous • VMware has ~56% of the market • Hyper-V is growing rapidly, but not necessarily at the expense of VMware
- 11. 11 What Do They Need? 11 Cloud computing platform needs to be agnostic
- 12. 12
- 13. 13 Mixed Hypervisor Support Matters • Advantages of running multiple hypervisors ‒ Workload optimization ‒ Licensing flexibility • Cloud can simplify heterogeneity ‒ Single control plane ‒ Schedule on any server
- 14. How Can I Make it Happen?
- 15. 15 How Do I Do It?
- 16. 16 How Do I Do It? • Major upgrade to driver in Havana • Compute node dedicated to communicating with vSphere • VMware NSX plug-in for Neutron • Cluster or clusters in vSphere dedicated to OpenStack virtual machines • Bridge interface on hosts for VLAN traffic Please don't use that! VMware driver added to OpenStack as of Grizzly
- 17. 17 Limitations • No iptables = no security groups • Havana—No Cinder support (EULA limitations) • Icehouse has new VMDK driver for Cinder • No live migration (from OpenStack)
- 18. 18 How Do I Do It?
- 19. 19 How Do I Do It? Hyper-V driver usable as of Grizzly Setup virtual switching Enable iSCSI initiator service Configure Shared-Nothing Live Migration Install Nova-Compute
- 20. 20 Limitations No iptables = no security groups No serial/VNC console—Must use RDP Vlan and Routing is only supported on Hyper-V when using the Quantum / Neutron Hyper-V Agent

- 25. 25 Image Properties If creating a VMware image, you may need to use Virtual Disk Manager to convert to an ESX-compatible format vmware-vdiskmanager -r <vmdk file> -t 4 <new file>
