Oracle VM 3.4.1 Installation
- 1. Today we are not going to install Oracle VM 3.3.3 Instead we are going to install Oracle VM 3.4.1
- 2. Simo Vilmunen Oracle eBS 10+ years Technical Architect and DBA Oracle Databases 15+ years Lately focused on virtualization & infrastructure of Oracle technology stack
- 3. Terminology for this session OVM = The actual Oracle VM OVM Manager = Management GUI OVS = Physical server under virtual machines VM = Virtual Machine Server Pool = Clustered physical servers for VMs Repository = Storage area for relevant files
- 4. Oracle VM Architecture Oracle VM Manager Web GUI Management Server Oracle VM Server Dom0 Domu Domu Domu Hypervisor Oracle VM Server Oracle VM Server
- 5. OVM Manager installation package Three (3) or more servers OVS installation package Patience People What we need for installation?
- 6. Let’s start with planning.
- 7. • Total count of CPU and RAM • Use www.spec.org to get estimate on current hardware capability • Spec CINT2006 benchmarks for processor per hardware vendor • Calculate total score for your hardware per Oracle VM server pool Server Processor Amount Spec CINT2006 processor score Total score RAM MT 1 E5640 1 119 119 16 MT 2 E52609 2 112 224 16 DB 1 E5640 2 119 238 64 DB 2 E5-2680 2 166 332 64 DB 3 E5-2650v2 2 341,5 683 64 Server pool 1 Server pool 2 How are you currently utilizing your hardware How many instances are you running Future requirements Licenses Plan your initial Oracle VM architecture (Oracle VM server pools)
- 8. 1. Processor limit per server 2. Processor frequency and cores 3. Memory 4. Network cards 5. Software licenses Hardware • Oracle Hardware Certification List for Linux and Oracle VM http://linux.oracle.com/pls/apex /f?p=117:1:0::NO:RP:: • Future requirements What to consider Decide your hardware setup
- 9. For Oracle VM 3.4.1 Oracle VM Server ISO patch ID 22902487 Oracle VM Manager Install/Upgrade ISO patch ID 22902502 Google: Oracle VM downloads
- 10. And now we can continue with installation.
- 11. To start OVM Manager installation follow readme. Mount ISO file to Linux host as root. Execute runinstaller.sh as root. Installation takes around 15 minutes to complete.

Oracle VM Manager UI: https://demovm.local:7002/ovm/console Log in with the user 'admin', and the password you set during the installation.
- 14. OVM Manager is running now.
- 15. Now it’s time to install OVS. Boot server from downloaded OVS ISO and install OVS.
- 16. 1 2 3 4 5 6 7 8
- 17. Discover just installed OVS server
- 18. OVS server is visible now in OVM Manager.
- 19. Oracle VM requires few networks Server Management Cluster Heartbeat Live Migration Storage network VM Network Add correct port from OVS to correct network.
- 20. Still needs storage access. iSCSI & multipath settings by default are not always set how your storage vendor requires.
- 21. And access to SAN
- 22. Oracle VM Storage Server pool file system holds the server pool and cluster data, and is also used for cluster heartbeat. Shared repository holds relevant data for operations. Virtual Machine files & disks, templates, ISOs and virtual appliances You can still assign disks directly from your storage system to VMs. 20G 500G
- 23. Add storage for server pool filesystem & VM repository
- 24. Create server pools as you require. We have separeted production / test pools for database & applications. Think of: Licensing Usage Hardware capability
- 25. Repository holds required files for specific server pool. Unless you have repository via NFS.
- 26. Installation and setup is now complete. Now the actual OVM can be utilized by creating virtual machines. Repeat the OVS process to as many servers as required.
- 27. Oracle has variety of prebuild templates available. Use them! Templates are optimized for OVM and create good starting point for your own gold templates.
- 28. Import template.
- 29. And create virtual machine from template.
- 30. For VMs the assigned disks will show up under info Virtual disk assigned from repository Physical disk assigned from storage system
- 31. Now you can manage your VM from OVM Manager. Live migration is only supported without hard partitioning. Hard partitioning can only be done from command line with OVM tools or editing vm.cfg.
- 32. How we have setup Oracle VM
- 33. Oracle VM 3.3.3 Dell Compellent SAN with 10GbE iSCSI (multipath) four server pools test application servers test database servers production application servers administration tools Dell M630 2x Intel E5-2667 v3 (3.2 GHz, 8c/CPU) X11 Intel x520 for 10GbE iSCSI 320GB RAM Intel x520 for 1GbE LAN
- 34. Identical hardware • Improved fault tolerance for failures • Easier manageability • Scalability possibilities Administration pool • Consolidate monitoring and administration services • Reused hardware Administration pool OVS OVS OVS OVS Test Management Monitoring Configuration management Development tools OVM Manager EM 12c non-prod MT pool OVS OVS OVS OVS non-prod DB pool OVS OVS OVS OVS prod MT pool OVS OVS OVS
- 35. Few things we have noticed with Oracle VM.
- 36. Enable hyperthreading from BIOS for OVS to maximize vCPU amount Number of dom0 vCPUs to match your configuration for optimal performance dom0_vcpus_pin dom0_max_vcpus=16 Backup mysql DB! That’s all you backup anyway.
- 37. Review iSCSI & sysctl configuration SAN refresh is slow and annoying if you work lot with LUNs - limit LUNs presented Use jumbo frames for iSCSI network
- 38. 0 50 100 150 200 250 300 0 500 1000 1500 2000 2500 OVS VM Broadcom VM tuned VM Intel VM xenblk-front VM disk alignment Throughput MB/s Latency (ms) About performance with iSCSI Linux disk alignment is a MUST!
- 39. Installing Oracle VM is relatively easy & fast Make sure your hardware is certified for production use Pay attention to performance tuning Think of your VM backup strategy

Editor's Notes
- #3: Started as Oracle Developer, quickly learned basic DBA skills and continued several years as DBA doing installations, backup&restore and basic administrative work but all the time more and more focus with performance tuning (8i through 11gr2) After some resistance learned eBS skills with 11.5.9 and then with current company 11.5.10.2 to 12.1.3
- #8: Go through all hardware utilization reports: SAN, OS utilization (use OEM), AWR for databases (OEM) Total number of instances you have now and their average usage. What do you expect in the future so there is size to grow. How many licenses you have currently because it will limit the setup. Initial server pool setup how do you want to divide the instances. Do you want to put databases in one pool and application servers in another or do you want to separate by application etc We measured current HW capability using spec int 2006 (compute-intensive integer performance) benchmarks and checked the matching or closest HW combination against our existing HW Made list of current HW which had the processor type, amount and cint2006 score per CPU and total. And RAM per each server. This gave good baseline what we have currently
- #9: From hardware vendor how many CPUs can you have in one server, what are options for CPU frequency and cores, how much memory should one server have. Story about CPU option limiting RAM Network cards should be looked closely and investigate deeper. Review HCL list to see what are currently supported .. Some new HW takes time to come up in the list and Oracle support seems to pay attention to this. And size HW based on future requirements. Scaling is relatively easy as you can just add servers when needed (although licensing) Explain the excel made
- #31: Doing live migration on hard partitioned VM will lose hard partitioning (and license implications)
- #32: Doing live migration on hard partitioned VM will lose hard partitioning (and license implications)
