Presentation I kept at OUGF Harmony'16 about installing Oracle VM

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

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

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

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.

12. [root@demovm dvd]# ./runInstaller.sh

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

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

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
