What’s new in XenCenter

September 21, 2023

Contributed by:

XenCenter is updated independently of the version of XenServer or Citrix Hypervisor. Ensure that your XenCenter version is regularly updated to the latest version.

The latest version of XenCenter is version 2023.3.1 (preview). You can download this version of XenCenter from the XenServer downloads page.

Note:

XenCenter 2023.x.x is currently in preview and is not supported for production use. Note that any future references to production support apply only when XenCenter 2023.x.x and XenServer 8 go from preview status to general availability.

You can use XenCenter 2023.x.x to manage your XenServer 8 and Citrix Hypervisor 8.2 CU1 non-production environments. However, 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 2023.x.x on the same system. Installing XenCenter 2023.x.x does not overwrite your XenCenter 8.2.7 installation.

What’s new in 2023.3.1

Released Aug 24, 2023

A delivery of regular updates to XenServer 8 is made available through XenCenter, allowing you to benefit from a more efficient release process that delivers new features and bug fixes at a faster cadence than was previously possible. For more information, see Update your hosts.
XenCenter updates can be downloaded and applied from within the UI. For more information, see Update XenCenter.
You can use XenCenter to manage your XenServer 8 non-production environments.
PuTTY is no longer bundled with XenCenter. To launch an SSH console to a XenServer host by using XenCenter, you must install an external SSH console tool and ensure that XenCenter is configured to use it. For more information, see Configure XenCenter to use an external SSH console.

Fixed issues in 2023.3.1

This update includes fixes for the following issues:

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)

Known issues in 2023.3.1

This update contains the following known issues:

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)
It is not advisable to apply updates to the same pool from concurrent instances of XenCenter because this might disrupt the update process.

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
In XenCenter, if you create a VM using an earlier version of XenServer and then import, migrate, or upgrade that VM to XenServer 8, the maximum number of vCPUs supported on that VM might be incorrectly displayed.

This applies to:
- VMs imported into XenServer 8 using OVF/OVA files created from a Citrix Hypervisor 8.2 (or earlier) host.
- VMs migrated from a Citrix Hypervisor 8.2 (or earlier) host to a XenServer 8 host.
- VMs created on a Citrix Hypervisor 8.2 (or earlier) host before upgrading it to XenServer 8.
To workaround this issue, use the xe CLI or the management API to increase the number of vCPUs on your VM.
If you create a VM by importing a VHD file, you cannot increase the number of vCPUs above 16.
In pools with GFS2 SRs, using XenCenter to generate a server status report (SSR) can fail. To work around this issue, generate your SSRs by running the following command in the host console: xenserver-status-report. (CA-375900)
