What’s new in XenCenter

XenCenter is updated independently of the version of XenServer or Citrix Hypervisor. To remain supported, ensure that you are using the latest XenCenter version.

You can download XenCenter YYYY.x.x from the XenServer downloads page.

After installing a version of XenCenter YYYY.x.x, you can receive further updates to XenCenter automatically. For more information, see Updating XenCenter.


XenCenter YYYY.x.x is not yet supported for use with Citrix Hypervisor 8.2 CU1 in production environments. To manage your Citrix Hypervisor 8.2 CU1 production environment, use XenCenter 8.2.7. For more information, see the XenCenter 8.2.7 documentation.

You can install XenCenter 8.2.7 and XenCenter YYYY.x.x on the same system. Installing XenCenter YYYY.x.x does not overwrite your XenCenter 8.2.7 installation.

What’s new in 2024.1.0

Released Mar 06, 2024


Update to this latest version of XenCenter before applying updates released after Mar 06, 2024 to your XenServer pool.

XenCenter 2024.1.0 or later is required to receive production support with XenServer 8.

This update contains the following new features:

  • Improved update guidance: We’ve added more nuanced guidance for the tasks that are performed as part of updates. These changes are designed to minimize the disruption to your VMs that these update tasks might cause. Tasks are categorized into Mandatory, Recommended, Full-effectiveness, and Live patch. These categorizations enable you to judge whether a update task that might cause downtime or minor disruption for your hosts or VMs is necessary for your environment and risk profile. For more information, see Updating your XenServer hosts.

  • SNMP: You can now use SNMP and any NMS of your choosing to remotely monitor resources consumed by XenServer. With this feature, you can also configure traps to monitor your XenServer hosts, which are agent-initiated messages that alert the NMS that a specific event has occurred in XenServer. For more information, see Monitoring host and dom0 resources with SNMP.

  • Changes to licensing: If you used XenServer 8 during its public preview phase with a Citrix Virtual Apps and Desktops license, this license is now deprecated and will not be supported with XenServer 8 in future. XenCenter now alerts you that this license is deprecated and prevents you from upgrading from Citrix Hypervisor 8.2 CU1 to XenServer 8 until you apply a XenServer Premium Edition license to your hosts.

    To run Citrix Virtual Apps and Desktops workloads on your XenServer pool, you require a XenServer Premium Edition license. For more information, see https://xenserver.com/buy.

    Existing customers can request to participate in our promotion and receive up to 10,000 XenServer Premium Edition socket licenses for free. Learn more.

This update includes the following improvements:

  • The Advanced Options panel has been removed from VM Properties. This panel contained obsolete options that are no longer required.
  • In the Virtual Interface Properties pane, XenCenter now shows the QoS limit in MBit/s.
  • Units shown in XenCenter have been corrected to reflect accurately the base of the unit (1000 or 1024). Wherever the unit is calculated with multiples of 1024, XenCenter displays kiB, MiB, GiB, TiB, and so on. Wherever the unit is calculated with multiples of 1000, XenCenter displays kB, MB, GB, TB, and so on.
  • Usability improvements to the VM Export Wizard.
  • XenCenter now shows the object’s UUID on the Properties Dialog > General tab for all objects accessible through XenCenter.

Fixed issues in 2024.1.0

  • Previously, XenCenter allowed you to rolling pool upgrade your hosts to the same version they are currently running, which left the pool in a broken state. XenCenter now prevents this behavior.
  • Sometimes, in the VM Snapshot Schedule Properties dialog, the Snapshot Schedule panel doesn’t load. (CA-387186)
  • XenCenter can incorrectly allow an upgrade to proceed when there are failed pre-checks. (CA-386488)
  • Sometimes, VMs are not restored to their original host after exiting maintenance mode. (CA-387197)
  • Updates are not made availble to users on Standard Edition. (CA-389235)
  • XenCenter does not prompt you to save your connection state on first opening. (CA-380853)
  • When pinned to the taskbar, the XenCenter taskbar icon disappears after a XenCenter update. (CA-379341)
  • XenCenter does not preserve the power state when exporting a suspended VM as an XVA. (CA-368247)
  • XenCenter incorrectly blocks pool operators from importing appliances and VM admins from exporting appliances. (CA-389487)

Known issues in 2024.1.0

  • After a standalone host is rebooted, including when it’s rebooted after applying updates, the host’s General Tab does not display the status of the system correctly. We recommend that you refresh the host’s General Tab by clicking on a different object and back on the host, or by disconnecting and reconnecting.
  • Some updates that do not include guidance about update tasks are not displayed in the By update view. To see these updates, you can look in the By server view. (CA-389580)
  • Changing the font size or dpi on the computer on which XenCenter is running can result in the user interface appearing incorrectly. The default font size is 96 dpi; Windows 8 and Windows 10 refer to this font size as 100%. (CA-45514) (CAR-1940)
  • In XenCenter, when you attempt to import an OVF package or a disk image from a folder containing a hash character (#) in its name, the import fails with a null reference exception. (CA-368918)
  • When attempting to run XenCenter from the command line while XenCenter is already running, any arguments with whitespace characters must be wrapped in both double and single quotes: “‘example’”. (CA-389317)
  • If you connect to the same XenServer pool with multiple instances of XenCenter, neither XenCenter shows available updates. To attempt to work around this issue, you can disconnect and reconnect XenCenter from the pool. (CA-389319)
  • If more than one instance of XenCenter is attempting to install multiple updates on a pool, a host might fail to install with the error: “The update has already been applied to this server. The server will be skipped.” This error causes the whole update process to stop. (CA-359814)

    To workaround this issue:

    1. Ensure that no other XenCenter instance is in the process of updating the pool
    2. Refresh the update list in the Notifications > Updates panel
    3. Start the update from the beginning
  • When updating to XenCenter 2024.1.0 from an earlier version, you encounter an error if you attempt to Download XenCenter v2024.1.0.xxx source code.

  • On Windows 10 (1903 and later) VMs, there can be a delay of a few minutes after installing the XenServer VM Tools before the Switch to Remote Desktop option is available in XenCenter. You can restart the toolstack to make this option appear immediately. (CA-322672)

  • XenCenter gives an invalid error when you attempt to create multiple VM disks totalling > 2 TB. (XSI-1467)
