XenServer 7.6 Now Available for Download!

Hello everyone,

Citrix is pleased to announce general availability of XenServer 7.6, the latest release for those following the Current Release model. For information regarding the differences between the Long-Term Service Release (LTSR) and Current Release (CR) models offered by Citrix, please refer to the article published on the Citrix blog site.

7.6 introduces official support for thin provisioning on block storage for XenServer virtual disk Storage Repositories along with Networking SR-IOV for enhanced system I/O performance. Initially available as “experimental” features in the 7.5 CR release, rapid and wide implementation of these features in production environments is anticipated as customers look to achieve significant savings in storage cost and capacity as well as better overall system performance.

If it's been some time since your organization has upgraded its XenServer virtual environment, please review the following list, which highlights the various features introduced in recent versions (prior to 7.6) that are helping our customers get the most out of their virtual workloads.

7.5 CR:

  • Larger XenServer Resource Pool size: XenServer now supports up to 64 hosts participating in a resource pool
  • Support for USB Pass-Through, enabling physical USB devices to be passed through to a VM so the guest OS can use the physical USB device as a local USB device

7.1 CU1 LTSR:

  • Automated updates to simplify host maintenance
  • Delivering Windows VM drivers via Windows updates (WSUS)
  • Health Check (via Citrix Insight Services) to monitor the health of XenServer hosts
  • Live-Patching, enabling hosts to be updated (patched) without rebooting to minimize downtime
  • PVS-Accelerator -reducing/eliminating boot storms while dramatically improving virtual desktop performance
  • SMB storage, providing even more options for SRs
  • Bitdefender Hypervisor Introspection (HVI), which scans raw memory at the hypervisor later to detect and protect virtual environments from sophisticated IT attacks (i.e., viruses, malware, ransomeware and rootkit exploits)
  • Support for Nutanix, combining the benefits of a single software stack (XA/XD/XS) with the cost-effective scale and management benefits provided by hyper-converged infrastructure

Consistent with previous releases, XenServer 7.6 delivers new features to help our customers get the most out of Citrix Virtual Apps and Desktops.

For additional information pertaining to XenServer, which, along with many other Citrix products, is currently going through the rebranding process (and will soon be referred to as “Citrix Hypervisor”), please visit the XenServer/Citrix Hypervisor page on Citrix.com.

Until next time,

Andy

At some point will it launch 7.1 CUXX with the new features implemented until now (7.2 - 7.6) or do we have to wait for one in the XenServer 8xx* version?

Will the cumulative updates be just update packages already released or will they implement new features?

This information is important for companies to think about migration plan, as it is not clear if for example, from version 7.6 we can upgrade to 7.1 CU2 for example.

Or how soon will a new Cumulative Update be released?

Hi Daniel,

Any new features introduced between 7.2 and 7.6 CR will not be back-ported to 7.1 CUxx LTSR. CUxx is a roll-up of bug fixes only. New features will be introduced in the 8.x release.

Regarding the timing of the next 7.1 CU release, please refer to the Citrix Product LifeCycle matrix (https://www.citrix.com/support/product-lifecycle/milestones/citrix-hypervisor.html), which should provide some guidance to help you with your update/migration planning.

Lastly, customers can move from LTSR to CR or CR to LTSR at their discretion, but it is not recommended to move backwards (downgrade). For example, if you are currently running 7.6 CR, moving to 7.1 CU1 LTSR is not recommended. In this scenario, you could wait for the 8.x LTSR release and then upgrade/move from 7.6 CR to 8.x LTSR. Remember that LTSR releases are designed for customers whose IT requirements are satisfied by the features available in the LTSR release (i.e., they do not need or are not looking to obtain any new features) and prefer stability (i.e., do not want to or cannot upgrade frequently), while CR releases are designed for those customers who like to be able to access new features as they are made available (approximately every quarter or so).

Thank you,
Andy

Rafique,

You do not need to install any additional components or fixes for the host machine to recognize local storage. In fact, when you installed XenServer, you were prompted to select the storage to use for the installation. If you selected local storage and the installation completed successfully, the same storage should be available to you within XenCenter for use as a Storage Repository (SR) for virtual disks.
