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.
Note:
Unless otherwise specified, the XenCenter articles apply to both XenServer and Citrix Hypervisor releases, even if only XenServer is explicitly mentioned.
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.
What’s new in 2025.2.0
Released May 07, 2025
This update contains the following improvements:
- Improved live patching advice. XenCenter displays extra guidance when partial live patches are available for a set of updates. Use this information to avoid unnecessary host reboots.
- Improvements to the VM import mechanism. You are now prompted to select a template when importing VMs from disk images, which provides greater consistency between imported VMs.
- Ensure compatibility between XenCenter and the latest XenServer updates. If you attempt to apply a set of updates to your pool that are not compatible with your current version of XenCenter, XenCenter blocks the update and prompts you to update your XenCenter to the latest version. This check ensures that your XenCenter does not lose connection with your pool during the update process.
- Improvements to the root password change options. The option to change the pool root password is now shown only on the Pool menu. It was previously also shown on the Server menu.
- When you select multiple pools or standalone hosts to apply licenses to at the same time, XenCenter now handles these pools in parallel, rather than sequentially. This change speeds the licensing process.
- When a host exits maintenance mode, the previously evacuated VMs are now returned to it in parallel instead of one at a time. This speeds up the process of moving VMs back to their original host.
This update contains the following change in behavior:
- XenCenter no longer associates the following file types with itself: OVF, OVA, VHD, and VMDK.
Fixed issues in 2025.2.0
- For XenServer 8.4 pools, the performance graphs in XenCenter are blank. (XSI-1824)
- In Networking > Properties, changes to the Automatically add network to new VMs setting are not saved. (CA-407424)
- When XenCenter connects to a large pool with high availability enabled, if a host in that pool fences, XenCenter can crash and report an unexpected error. (CA-404129)
- The Install Update dialog can show an error when restarting the toolstack. (CA-399639)
- An uncaught exception when attempting to view the details of the update while installing the update. (CA-407544)
- In the host Properties dialog, on the Log Destination panel, XenCenter doesn’t allow you to include a port in the field. (CA-404628)
- Incorrect help link on the New Security Certificate dialog. (CA-404836)
- Sometimes, when an import operation is interrupted, the partially imported VM cannot be deleted and the import cannot continue. (CA-380982)
- In the Copy VM dialog, if there is no storage network available to choose, the dialog allows you to proceed to the next step. This behavior causes an error. (CA-408106)
- After shutting down and reopening XenCenter, it sometimes fails to display saved hosts and pools. (CA-401317)
- The XenCenter logs can include an excessive amount of Citrix Virtual Apps and Desktops connection manager messages. (CA-408197)
- When using the Install Update wizard to update more than one standalone host, the wizard does not exit gracefully. (CA-407549)
- The data source ‘runstate_blocked’ is incorrectly shown as ‘runstate_idle’. (CA-409548)
- When you open the Conversion Manager wizard, the New Security Certificate dialog repeatedly opens after it is canceled. It continues to open even if the Conversion Manager wizard is closed. (CA-409460)
- When connecting to a pool that is part of an AD domain as a user within that domain that has not been explicitly added to the pool, the operation hangs. (CA-406952)
- An error can occur when a host exits maintenance mode during an emergency transition of the pool coordinator. (CA-404662)
Known issues in 2025.2.0
-
When exporting one or more VMs as an OVF or OVA file from XenCenter and then importing them back, XenCenter raises an error after the import process ends. Attempting to start any of the imported VMs produces a second error. (CA-411119)
To work around this issue, set the domain type of the VM by using the following xe CLI command:
xe vm-param-set domain-type=hvm uuid=<vm_uuid> - If XenCenter manages many pools that use the same AD account, when the AD account password changes, XenCenter attempts to log in to all pools with the old password and can, as a result, lock out the AD account. (CA-404715)
- 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 a different object and back on the host, or by disconnecting and reconnecting.
- 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 10 refers 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)
-
(Citrix Hypervisor 8.2 Cumulative Update 1 only) 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 work around this issue:
- Ensure that no other XenCenter instance is in the process of updating the pool.
- Refresh the update list in the Notifications > Updates panel.
- Start the update from the beginning.

Fixed issues
- When using XenCenter to change the DNS settings, the IP config on the pool can change without warning. (CA-389459)
- The Active Directory domain check when adding a host to a pool can incorrectly fail. This failure is caused by the check being case-sensitive. (CA-399256)
- When creating VMs or importing XVAs, XenCenter allows selection of host or pool with unavailable SRs. (CA-359985)
- The Exit Maintenance Mode dialog offers to restore VMs it did not shut down, suspend or evacuate. (CA-311142)
- After resizing the main panel in XenCenter, long pool or server names can obscure the licensing or log-in information. (CA-399240)
- While applying hotfixes to a Citrix Hypervisor 8.2 Cumulative Update 1 pool or server, if you select to shut down VMs from the pre-checks panel, the shutdown operation can report an error even though it succeeds. (CA-389409)
- Not all VMs are restored when XenCenter brings a host out of maintenance mode. (CA-400059, CA-400930)
- Miscellaneous user experience issues. (CA-400057, CA-401369, CA-375830, CA-393494)
XenCenter 2024.3.1
Released Oct 10, 2024
What’s new
This update contains the following new feature:
- For Windows VMs, custom templates, or snapshots, you can now manage I/O driver updates for XenServer VM Tools through Windows Update in the New VM wizard in XenCenter. For details on enabling I/O driver updates through Windows Update, see Overview of VM creation steps.
Fixed issues
- If a VM’s
has-vendor-devicefield is set to true and you then convert the VM into a template or a snapshot, XenCenter fails to retain this value, causing new VMs created from the template or snapshot to have an incorrecthas-vendor-devicevalue. (CA-391310) - During a silent installation of XenCenter, the installer fails to remove the previous version because the sequence that detects existing installations only runs during standard UI installations. (CA-399231)
- When managing large numbers of Citrix Hypervisor 8.2 CU1 hosts in XenCenter, you might encounter GUI performance issues, including high CPU usage and occasional UI freezes. (CA-397980)
- Using XenCenter 2024.1.0 or later to set or edit a custom field with a value for an object causes any values in the object’s
other_configto be deleted. This issue can cause unexpected behavior depending on the object and your environment. We strongly recommend that you do not add or edit custom field values. (CA-397587) - For XenServer 8.4 pools, when the VM Groups feature is disabled or unlicensed, some elements and menu options are incorrectly shown in XenCenter. (CA-396046)
- In the Pre-checks panel of the Install Update wizard, an info pop-up states that there are pending tasks to complete for snapshots, although this guidance is only ever applicable to VMs. (CA-395739)
- When performing a Rolling Pool Upgrade in XenCenter, the Rolling Pool Upgrade wizard’s final page incorrectly displays 24-hour log timestamps as 12-hour time. (CA-393819)
- When viewing your pool or host, the licensing information does not display correctly if your license has expired. (CA-392951)
- In XenCenter 2024.1.0, the Properties pane of your pool or VM occasionally stops rendering correctly. (CA-389831)
- When a host is offline, the shared storage is reported as broken even though all the active hosts are correctly connected to the shared storage. (CA-353531)
XenCenter 2024.3.0
Released Aug 22, 2024
What’s new
This update contains the following new feature:
-
(XenServer 8.4) You can now assign your VMs to anti-affinity placement groups that are started on hosts in your pool according to the following anti-affinity placement rules:
- No single host is the only place all VMs in a particular group are running.
- The count of VMs within the group for each host is as even as possible.
When a VM in one of these groups is started or evacuated from a host, XenServer chooses to place the VM on a host that enables the VM group to follow these rules as closely as possible.
For more information, see Manage VM groups.
This update contains the following improvements:
- (XenServer 8.4) XenCenter now supports using IPMI for host power-on. For more information, see Configuring Host Power On.
- XenCenter shows a warning if you attempt to create a GFS2 SR on a thin-provisioned LUN. This configuration is not recommended and can cause you to run out of space. For more information, see Thin-provisioned shared GFS2 block storage.
Fixed issues
- 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 you select multiple VMs in the Resources pane, the actions available from the VM menu and the actions available on the context menu are inconsistent. (CA-61207)
- Some shortcut keys in the context menu are not unique. (CA-395822)
- Inaccurate information can sometimes be displayed in the Boot Options panel for a VM. (CA-396230)
- When you select multiple items in the Organization or Infrastructure views and then switch between these views, your selections are lost. (CA-391372)
- After Aug 17, 2024, automated updates to XenCenter 2024.2.1 stopped working. This failure is caused by an expired certificate. Automated updates have now resumed with the XenCenter 2024.3.0 release.
XenCenter 2024.2.1
Released Jul 09, 2024
What’s new
This update includes the following improvements:
- Added information to the XenCenter installation wizard stating that the current installation removes all previous versions of the XenCenter application from your device.
- Improved the Conversion Manager wizard to display a warning before starting the conversion process if your VMware ESXi/vCenter VMs are running guest operating systems that are not supported for conversion.
- Removed the VM Recovery Mode feature.
Fixed issues
- On Citrix Hypervisor 8.2 Cumulative Update 1 hosts, when attempting to apply a hotfix through automated updates, XenCenter incorrectly shows the warning “The license is deprecated and may revert to Trial Edition if updates are applied”. (XSI-1676)
- When performing actions related to Workload Balancing (such as connecting, pausing, or resuming), XenCenter might fail to show the correct state of the Workload Balancing appliance. (XSI-1674)

XenCenter 2024.2.0
Released Jun 06, 2024
What’s new
Note:
- XenCenter 2024.2.0 is required to receive production support with Citrix Hypervisor 8.2 Cumulative Update 1 and XenServer 8.4.
Upgrade notes:
- XenCenter 2024.2.0 supersedes earlier versions of XenCenter, including XenCenter 8.2.x. When you install XenCenter 2024.2.0, it removes other versions of XenCenter on your system.
- If XenCenter 2024.2.0 is the first version of XenCenter with a version format YYYY.x.x that you have installed on your system, it imports your server list from any instance of XenCenter 8.2.x on the system. Passwords are not imported.
-
If you already have a version of XenCenter YYYY.x.x installed in parallel with XenCenter 8.2.x, this version does not import your server list from XenCenter 8.2.x. To migrate your server list from XenCenter 8.2.x, complete the following steps in order:
- Export your data from XenCenter 8.2.x. Go to File > Export Server List.
- Install XenCenter 2024.2.0.
- Import your data into XenCenter 2024.2.0. Go to File > Import Server List.
For more information, see Exporting and Importing a List of Managed Servers.
This update contains the following new features:
-
(XenServer 8.4) Import a VHDX or AVHDX disk image as a VM: You can now import a VHDX/AVHDX file into a pool or specific host as a VM. VHDX is an improved version of the VHD format that provides better performance, fault tolerance, and data protection features in addition to a larger capacity. For information on how to use the XenCenter Import wizard to import a VHDX/AVHDX file, see Import Disk Images.
If you are a Citrix customer, you can also use this feature to migrate your VMs from VMware to XenServer. As part of its software streaming technology, Citrix Provisioning stores a shared disk image (vDisk) as a VHDX/AVHDX file. By using the XenCenter Import wizard to import a VHDX/AVHDX file, you can easily migrate your vDisk from VMware to XenServer. For more information, see Migrating from VMware.
-
Close TCP port 80 for a pool’s management interface by using XenCenter. For more information, see Change Pool Properties.
You can also view the status of port 80 for a pool or server in its General tab in the Management Interface section.
This update includes the following improvements:
- XenCenter lists the make and model of the host hardware on the host’s General tab.
- Improvements to the display of licensing information.

- Customers with a Standard Edition license are not able to do GPU Pass-through to a Windows VM through XenCenter.
- In XenCenter 2024.1.0, when you create a new folder it does not appear until you disconnect and reconnect to the modified pool. Also, when a folder is deleted it remains visible until you reconnect.
- Importing dynamic VHDs results in an error.
- Sometimes, the License Manager can assign a non-selected license and refuse to release the license.
XenCenter 2024.1.0
Released Mar 06, 2024
What’s new
Note:
You must be using this version XenCenter or later before applying updates released after Mar 06, 2024 to your XenServer pool. Always install the latest version of XenCenter.
This update contains the following new features:
-
(XenServer 8.4) 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 an 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.
-
(XenServer 8.4) 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 8.4 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 8.4 in future. XenCenter now alerts you that this license is deprecated and prevents you from upgrading from Citrix Hypervisor 8.2 CU1 to XenServer 8.4 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 information about getting a license, see the XenServer website.
XenServer is now an entitlement of the Citrix for Private Cloud, Citrix Universal Hybrid Multi-Cloud, Citrix Universal MSP, and Citrix Platform License subscriptions for running your Citrix workloads. Read 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.
- The 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
- 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)
