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: Keep Your Virtualization Infrastructure Up to Date

It's important to keep all software versions and patches up-to-date, as one of the principles of good security practice. Oracle responds quickly to any potential security threat by incorporating the security fixes into errata updates. See recent security alert to address CVE-2015-3456 ("VENOM") here

The Oracle VM security architecture, by design, eliminates many security threats. The guidelines for secure deployment of virtualized solutions based on Oracle VM are largely based on network security. As these guidelines are generally applicable, they should always be reviewed for applicability in the context of each implementation and the security requirements and policies of the broader environment in which Oracle VM is deployed. Please review Oracle VM Security Guide to apply to your environment.

  • Oracle VM Server for x86 Security Guide for Release 3.3 HTML
  • Oracle VM Server for x86 Security Guide for Release 3.2 HTML
  • Oracle VM Server for SPARC Security Guide for Release 3.2 HTML

To be informed about any errata update, including security fixes, you can sign up here to receive notification on software update delivered to ULN for Oracle VM Server for x86, or you can browse the email archive.

Friday Spotlight: Develop in VirtualBox and Deploy to Oracle VM Server

Oracle has two widely used virtual machine technologies for x86: Oracle VM Server for x86 is oriented towards server applications, while Oracle VM VirtualBox is our popular desktop virtualization product. Each is designed for its target application: Oracle VM Server for x86 provides scale and performance for enterprise applications, while Oracle VM VirtualBox provides convenient and flexible desktop virtualization for end-users and developers.

VirtualBox makes it easy to share files between a host desktop or laptop and its VMs, so a programmer can develop code on the host and then test the software inside the VMs. A convenient use case is to develop a VM on VirtualBox, and then export it to Oracle VM Server for x86 where it can run in production. That leverages VirtualBox's graphic capability and ease of use for developer productivity with the ability to promote applications to the servers where they will run.

Converting a VirtualBox VM to an Oracle VM Server for x86 image has been described before, but it's even easier now than previously. First, remove the VirtualBox Guest Additions from the VM as documented in the VirtualBox User Manual. Then export the VM from VirtualBox (File -> Export Appliance). Copy the resulting .ova file to a web server that can be accessed by Oracle VM Manager, and import it as an assembly (Repositories tab, select the target repository, select the Assemblies directory, and click on the 'Import VM Assembly' icon). After the assembly has been imported, it can be used to create a template just as with other assemblies in Oracle VM.

Oracle VM VirtualBox is a user and developer-friendly desktop virtualization technology ideal for creating and testing applications, and Oracle VM Server is a robust server virtualization technology for running enterprise applications. Together, the two are a highly effective combination.

To learn more about Oracle VM VirtualBox and how to use VirtualBox to help with your test/development use cases, you can watch the recent webcast replay.

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.
