VMware released update 2 for vCenter Server 5.1 which adds some nice features and enhancements. If you haven’t updated to vSphere 5.5 yet make sure you update your 5.1 environment.

What’s new?

So what’s new with this update?

• vCenter Server is now supported on Windows Server 2012 R2
• Additional Guest Operating System Customization Support: vCenter now supports
  • Windows 8.1
  • RHEL 6.4
  • Windows Server 2012 R2
  • SLES 11 Service Pack 3
• Database support added for Microsoft® SQL Server® 2012 Service Pack 1

Another interesting point is a security update: Update to OpenSSL version openssl-0.9.8y addresses multiple security issues.

There is quite a list of resolved issues (sadly there is also a long list of know issues without a real fix), make sure you read the release notes prior to upgrading so you don’t run into any problems.

Besides upgrading your vCenter also remember to upgrade your ESXi hosts which have a new update as well.
