Changing Server Properties
Select any connected server in the Resources pane and click on the General tab to see its properties and current status. Click Properties to change the properties of a server.
General properties - Name, Description, Folder and Tags
You can change the name, description, folder, and tags for a server on the General Properties tab of the server’s Properties dialog box.
- To change the server’s name, enter a new name in the Name box.
- To change its description, enter new text in the Description box.
- To place the server in a folder or to move it to a different folder, click Change in the Folder box and select a folder. See Using folders for more information about using folders.
- To tag and untag the server and to create and delete tags, see Using tags.
iSCSI IQN (General tab)
The server’s iSCSI IQN is used to uniquely identify it when connecting to iSCSI storage repositories (SRs). XenServer hosts support a single iSCSI initiator which is automatically created and configured with a random IQN during host installation. The single initiator can be used to connect to multiple iSCSI targets (SRs) concurrently. For more detailed information about XenServer support for iSCSI storage, see the XenServer Administrator’s Guide.
Important: The iSCSI target (SR) and all servers in the pool must have different IQNs set. If a non-unique IQN identifier is used, data corruption can occur and/or access to the target may be denied.
To change the iSCSI IQN value for a managed server
Note: Before changing a server’s iSCSI IQN value, all existing SRs must be detached. Note also that changing the server IQN may make it impossible for the server to connect to new or existing SRs unless the storage target is updated appropriately.
- Select the server in the Resources pane, click on the General tab, and then click Properties.
- On the General tab in the Properties dialog box, enter the new value in the iSCSI IQN box.
- Click OK to save your changes and close the dialog box.
Custom Fields
Custom fields allow you to add information to managed resources to make it easier to search and organize them. See Using custom fields to find out how to assign custom fields to your managed resources.
Alerts
Use this tab to configure performance alerts for the server’s CPU, memory usage, and network activity. For more information, see Configuring performance alerts.
Email Options (standalone servers)
Use this tab to configure email notification for system alerts generated on a standalone server. This feature is configured at pool level for servers in a pool. See XenCenter Alerts for information on how to receive alert notifications by email.
Multipathing
Dynamic storage multipathing support is available for Fibre Channel and iSCSI storage repositories, and can be enabled via the Multipathing tab on the server’s Properties dialog.
See Storage Multipathing for information about enabling and disabling multipathing.
Power On (standalone servers)
Use this tab to configure the XenServer Host Power On feature, allowing managed servers to be powered on remotely. For more information about configuring this feature, see Configuring Host Power On. For servers in a pool, this feature is configured at pool level.
Log Destination
XenServer system log messages may be stored locally on the server itself or on a remote server.
The remote server must be running a syslogd daemon in order to receive the logs and aggregate them correctly. The syslog daemon is a standard part of all flavors of Linux and Unix, and third-party versions are available for Windows and other operating systems. The remote server should also be configured to allow remote connections from the hosts in the pool, and have its firewall configured appropriately.
To view or change the XenServer log destination
- Select the server in the Resources pane, click on the General tab, and then click Properties.
- Click on the Log Destination tab in the Properties dialog box and then:
- To store XenServer log message locally, click Local.
- To store XenServer log messages on a different server, click Remote and enter an IP address or the hostname of a server running the syslogd daemon.
- Click OK to save your changes and close the dialog box.
GPU
The GPU tab allows you to:
- Set a GPU placement policy
- Enable Intel GPU pass-through for Windows VMs
Placement Policy
The GPU tab allows you to set a host-wide policy to assign VMs to available GPUs to achieve either maximum density or maximum performance. Select an option based on your requirements.
The GPU tab displays Mixed setting only when different settings are used for different GPU groups, that is, when certain GPU groups are configured to achieve maximum density, and the rest are configured to achieve maximum performance. Customers should note that it is not possible to set or edit the Mixed setting using XenCenter. You should use the xe Command Line Interface if you would like to use different settings for different GPU groups.
Note: GPU Virtualization is available for XenServer Enterprise Edition customers or those who have access to XenServer through their Citrix Virtual Apps and Desktops entitlement. The GPU tab is displayed when the host meets the license requirements and also has GPUs that support various virtual GPU types. For more information, see About XenServer Licensing.
Integrated GPU passthrough
When your XenServer host is connected to an Intel GPU on an Intel Server, the XenServer host’s control domain (dom0) will be connected to the integrated GPU device. In such cases, the GPU will not be available for pass-through. Select This server will not use the Integrated GPU to disable the connection between dom0 and the GPU and reboot the host for the changes to take effect. For more information, see GPU.
Note: The XenServer host’s external console output (for example, VGA, HDMI, DP) will not be available after disabling the connection between dom0 and the GPU.
