Friday Spotlight: Adopting Oracle VM Manager for Oracle VM Server for SPARC guests

Customers using Oracle VM Server for SPARC (formerly called 'logical domains') are increasingly looking at Oracle VM Manager to provide a unified management platform with Oracle VM Server for x86.  While most customers use Oracle VM Server for SPARC's native command line interface or Oracle Enterprise Manager Ops Center, Oracle VM Manager provides

  • a management solution focused on Oracle VM virtualization supporting server pools, advanced VM life-cycle and policy management, and control over the networks and storage they depend on.
  • a graphical user interface, command line interface, and API common to Oracle VM on the x86 and SPARC platforms. Administrators can use the same interactions to control servers, VMs, networks and storage on both platforms from a single screen.

The natural question is how to move existing Oracle VM Server for SPARC guests domains (virtual machines) and servers to Oracle VM Manager for their existing guests.  There is no direct way to "adopt" existing servers and VMs, but there are ways to move them to Oracle VM Manager control.

The first step is to set up at least one SPARC server in an Oracle VM Manager server pool - more servers can be added later. Guest domains can be individually moved to the server pool. This is a "cold" process (guests must be down while being moved) and applies only to guest domains (domains using physical I/O like SR-IOV cannot be moved).  Optionally, servers can be redeployed under Oracle VM Manager as capacity requirements shift from the original deployment to the new pool.

The main consideration for moving a guest is storage. Virtual disks may be on SAN LUNs (typical for production use), physical disks, ZFS volumes, or files in a file system. Oracle VM Manager supports LUNs defined as "physical disks" presented from storage arrays, so moving those virtual disks is straightforward. If virtual disks are ZFS volumes or files they must be copied to storage under Oracle VM Manager control, typically an NFS-based Oracle VM repository. File-based virtual disk images are easy to import using the Oracle VM user interface. If the virtual disks are based on ZFS volumes or internal disks, use the 'dd' command to create virtual disk images that can be imported. (The virtual disks should not be in use while being copied). 

An optimization can be used for guest ZFS pools. Make the ZFS pool a mirror using a new virtual disk of equal size as ones already in the pool, Wait for the pool to resilver, and then 'zpool split' the new virtual disk from the pool, and upload the image file into Oracle VM Manager. The advantage is that resilvering copies only "in use" disk blocks, not residual erased data, so the resulting disk image may be substantially smaller.

Whichever method is used, customers already using Oracle VM Server for SPARC may further benefit from moving to Oracle VM Manager.

Friday Spotlight: Secrets of Storage Repositories with Oracle VM

Here is some insider information for those using Oracle VM. 

You use repositories in Oracle VM to store virtual resources such as ISO files, virtual disks and assemblies. Indeed you must have at least one repository to store the configuration files of your virtual machines.

Creating and populating your Oracle VM repositories is straightforward. Relocating repositories is a bit more involved.

You might want to answer the following questions:

  • Can you move an existing repository between server pools in your Oracle VM environment?
  • What happens to your repositories if you reinstall the Oracle VM Manager software?
  • Did your Oracle VM environment retain the UUID of the Oracle VM Manager from your previous environment
  • When building your recovery site as part of disaster-recovery operations do you have a plan to reclaim any repositories that were active in the failed environment
  • Could you get comprehensive answers to all these questions in 30 minutes

To answer these questions, you can view this series of 6 demos. You will learn the steps to reclaim your repositories. The first 4 demos introduce concepts that are important when relocating repositories. Demos 5 and 6 present practice scenarios where reclaiming repositories is a critical step for recovering virtual resources.

If the information in these demos is of use to you, you could consider taking the following courses:

You can take these courses by traveling to an education center as an in-class offering or from your own desk as a live-virtual offering.

Friday Spotlight: Oracle VM Server for SPARC 3.2 features

For this week's Friday spotlight, I want to highlight the improvements in live migration and virtual disk multipathin which were delivered as part of Oracle VM Server for SPARC 3.2 released in March 2015. 

  • Provide live migration performance enhancements, including parallel memory-mapped I/O and optimized firmware copying routines. These enhancements reduce the overall migration time and the time during which the migrated guest domain is suspended. 
  • Update virtual disk management for mpgroups to show and specify the selected path to the virtual disk backend. You can see the path that is currently used and dynamically request a path switch.

To learn more details about enhanced features please see the blog entries on live migration improvements and on disk multipathing.

Oracle Virtualization at Oracle OpenWorld 2013, Part 2

If you're attending Oracle OpenWorld 2013 (and we hope you are!), the Schedule Builder tool is now available for you. Schedule Builder lets you register for the sessions you want to attend during the show. If you're interested in Oracle Virtualization, there are a number of sessions, hands on labs, and product demos that will be interesting to you. I covered several of the sessions in part 1 of this series, and in this one I'm going to cover a few more sessions. In the 3rd part of this series, I'll cover the Hands On Labs and demo stations that you can visit.


What's New with Oracle VM Server for x86 and SPARC: A Technical Deep Dive (CON9544)
Oracle VM Server virtualization solutions provide users the best combination of price, performance, certification, and advanced features tailored for ease of deployment and management. Spanning both x86 and SPARC architectures, it's designed to support a diverse set of OS workloads such as Linux, Solaris, and Windows to meet the wide ranging demands of modern IT environments. Join us to get the latest technology updates on Oracle VM Server.

High Availability and Infrastructure Best Practices with Oracle VM (CON11258)
This session will provide practical details and best practices on building and scaling an Oracle VM environment for High Availability for Database and infrastructure best practices. From information gathering and planning to analyzing needs of your environment, you will learn to plan for growth in infrastructure components to accommodate failover, DR, HA and migration. This session will also cover the methods to reduce downtime during events like system upgrades and migration and troubleshooting during system outages.

Friday Tips #33

Happy Friday, everyone!

Our tip this week is from an excellent white paper written by our own Greg King titled Oracle VM 3: Building a Demo Environment using Oracle VM VirtualBox. In it, Greg gives you everything you need to know to set up Oracle VM Server inside of Oracle VM VirtualBox for testing and demoing. The section we're highlighting below is on how to configure the network interfaces of your virtual machines:

VirtualBox comes with a few different types of network interfaces that can be used to allow communication between the VM guests and the host operating system, including network interfaces that will allow the VM guests to communicate with local and wide area networks accessed from your laptop or personal computer. However, for the purpose of the demonstration environment we will limit the network communication to include access just between your desktop and the virtual machines being managed by VirtualBox.

The install process for Oracle VM VirtualBox creates a single host-only network device on your laptop or personal computer. Using the host-only network device will allow you to open a browser on your desktop to access the Oracle VM Manager running within the VirtualBox VM guest. The device will only allow network traffic between the VM guests and your host operating system, but nothing outside the confines of your laptop or personal computer.

We will need to add a second host-only network since the Oracle VM Server appliance has both eth0 and eth1 configured. You can choose to use eth1 on the Oracle VM Servers or not use them – the choice is yours. But, at least the host side network device will exist if you decide to use it.

Greg goes on to describe in detail how to setup the network interfaces, so you can head on over to the paper and get even more info.

See you next week!

Friday Tips #21

We hope you're having a great Friday! Here is our Friday tip:

Question:
Can I run VDI with just a single server?

Answer by Chris Kawalek, Senior Principal Product Director, Oracle Desktop Virtualization Marketing:
Absolutely! Oracle Virtual Desktop Infrastructure allows you to deploy on a single server for everything you need for a VDI deployment: brokering, running VMs, and storage. Properly outfitted, this single server should be able to support up to 180-190 users. You can read exactly how to do this, what kind of server it requires and more in this new white paper:

Oracle's Single Server Solution for VDI

Another great thing about this solution is that it easily scales. If you add a second server, you can use its own internal storage for HA. And you can add external storage and more servers if you want to scale even higher. And at no point do you have to install a different product or do a massive reconfiguration to grow from a small pilot or departmental deployment to an enterprise one.

We'll see you all next week!

Friday Tips #6, Part 2

Here is a question about updating Oracle VM:


Question:
How can I perform Oracle VM 3 server updates from Oracle VM Manager?

Answer by Gregory King, Principal Best Practices Consultant, Oracle VM Product Management:
Server Update Manager is a built-in feature of the Oracle VM Manager. Basically, Server Update Manager automatically configures YUM updates on all the Oracle VM Servers, pointing each to our Unbreakable Linux Network (ULN) update channel for Oracle VM. The servers periodically check with our Oracle YUM repository and notify the Oracle VM Manager that an update is available for each server. Actual server updates must be triggered by the Oracle VM administrator – they are not executed automatically.

At this point, you can use the Oracle VM Manager to put a server into maintenance mode which live migrates all the running Oracle VM Guests to other Oracle VM Servers in the server pool. Once all the Oracle VM Guests have been migrated, the Oracle VM administrator can trigger the update on the server. The entire process is documented in the Installation and Upgrade Guide of Oracle VM Documentation so I won’t spend time detailing the steps.

However, configuring the Server Update Manager is exceedingly simple. Simply navigate to the Tools and Resources tab in the Oracle VM Manager, select the link for Server Update Manager and ensure the following values are added to the text boxes as shown in the illustration below:

  • YUM Base URL: http://public-yum.oracle.com/repo/OracleVM/OVM3/latest/x86_64
  • YUM GPG Key: file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle

Every server in the pool will be automatically configured for YUM updates once you choose the Apply button.


Many thanks to Greg and Rick for providing the answers to this week's questions. If you want to ask us something, hit up Twitter and use hashtag #AskOracleVirtualization. See you next week!
