The tab-based navigation in XenCenter provides quick access to your managed resources without needing to open and close dozens of windows at the same time. The tabs available at any time depend on what you have selected in the Resources pane; for example, most resources have a General tab, while the HA and WLB tabs are available only when a pool is selected, and the Snapshots tab is only available when a VM is selected.
On this tab, you can run a console session on a VM or a managed server.
See also Run a Remote Console Session to read about the different types of remote VM console supported in XenCenter.
Switch to Remote Desktop
Switch to Default Desktop
Switches between Windows remote console types
Switch to Graphical Console
Switch to Text Console
Switches between Linux remote console types. You may need to enter your VNC password first when switching to a graphic console.
Open SSH Console
Opens an external SSH console as a pop-up window. This option is available
- On the host’s Console tab to access the Control Domain (Dom0) console
On the Console tab of a Linux VM to access the VM’s console.
Note: You must ensure that the Linux guest agent is installed on the VM to launch the SSH console.
Sends the Ctrl+Alt+Del key sequence to the remote console.
By default, most keyboard shortcuts are transmitted to the server or virtual machine when you use a remote console. However, your local system will always intercept the Ctrl+Alt+Del key sequence and prevent it from being sent if you try to type it in directly at the remote console.
Undocks the Console tab into a floating window.
To shut down or reboot a server, install XenServer Tools, shut down, reboot or suspend a virtual machine from within the floating console window, click in the top left corner of the window and then click on a command.
To use a different keyboard shortcut for docking and undocking the console, go to the XenCenter Options dialog box: click Tools > Options.
Opens the floating console window when it has been minimized or brings it to the front if it is hidden behind other windows.
Docks the floating console window back to the Console tab.
Scales the remote console screen to fit within the Console tab or window so that you can easily see everything on the remote console. Clear the check box to display the remote console screen at its normal size.
By default, the scale setting used in the Console tab is preserved when you undock the console or switch between console types (for example, VNC/text console), but this is configurable. To change this setting, go to the Console tab of the Options dialog box.
Displays the console in full-screen mode. Press Ctrl+Alt to exit full-screen mode; to use a different key sequence, go to the XenCenter Changing XenCenter Options dialog box.).
When you point to the top center of the screen in full-screen mode, the Connection bar is displayed, showing the name of the VM or server you are working on and including two controls: a Pin button to allow you to turn the Connection bar on permanently, and a Restore down button that you can click to exit full-screen mode.
You can control a number of console settings in the Options dialog box. For example, the text clipboard on your local machine is shared with the remote console by default, so that items you cut or copy will be placed on the clipboard and made available for pasting on either your local computer or on the remote console. You can turn clipboard sharing off and change a number of other console settings from the XenCenter Options dialog box; see Changing XenCenter Options.
View general properties of the selected container, virtual machine, server, resource pool, template or storage repository on the General tab; click Properties to set or change properties.
You can quickly copy any of the values shown on this pane to the Windows clipboard, for example, to paste into a text editor, by right-clicking on the value and then clicking Copy on the shortcut menu.
The GPU tab allows you to view or edit the GPU placement policy, view the available GPUs and virtual GPU types. The GPUs are grouped together based on the supported virtual GPU types. You can modify the virtual GPU types allowed on a particular GPU using the Edit Selected GPUs option. The horizontal bar in each group represents a physical GPU and it displays information about VMs running on the GPU.
For more information, see Configuring Virtual GPU.
- GPU Pass-through and Graphics Virtualization is available for XenServer Enterprise Edition customers, or those who have access to XenServer through their XenApp/XenDesktop entitlement. The GPU tab is displayed when the pool meets the license requirements and also has GPUs that support various virtual GPU types.
- There is no licensing restriction to use NVIDIA GPU pass-through for HVM Linux VMs.
On the HA tab for a pool, you can:
- Enable HA using the Configure HA button.
- Change the pool’s HA configuration using the Configure HA button.
- Disable (turn off) HA.
When HA has been enabled, you can see current HA status (failure capacity and server failure limit) and the status of the selected heartbeat SRs on the HA tab.
The Home tab allows you to add a server to the list of managed servers, open the XenCenter Help system, or open a browser window to find out more about XenServer and other Citrix products.
You can enable Dynamic Memory Control (DMC) and configure dynamic memory limits on the Memory tab. VMs can have a static memory allocation or can be configured to use DMC, which allows the amount of memory allocated to a VM to be adjusted on-the-fly as memory requirements on the server change without having to restart the VM. The Memory tab also lets you update the Control Domain (dom0) memory.
The Networking tab displays a list of networks configured on the pool, server, or the VM you have selected. It provides a centralized location to access or modify your network settings.
View detailed information about the physical network interface cards (NICs) on the selected server and configure NIC bonds on the NICs tab.
NIC bonding (or “NIC teaming”) can improve server resiliency by using two or more physical NICs as if they were one: if one NIC within the bond fails, the server’s network traffic will automatically be routed over the second NIC, ensuring server management connectivity. See Configuring NICs.
Note: You must use vSwitch as your network stack to bond four NICs. You can only bond two NICs when using Linux bridge.
Nutanix CVM Console
Note: The Nutanix CVM Console tab will be displayed on XenServer hosts that are installed as part of Nutanix Hyperconverged infrastructure.
The Nutanix CVM Console tab allows you to access the CVM terminal. A CVM is a privileged VM similar to XenServer’s control domain (dom0). The Nutanix software stack runs inside the CVM on each XenServer host. For more information, see the XenServer-Nutanix Integration Guide on the Citrix Product Documentation website.
View performance data for your VMs and managed servers on the Performance tab. Note that full performance data is only available for VMs with XenServer Tools installed.
The tab provides real-time monitoring of performance statistics across resource pools as well as graphical trending of virtual and physical machine performance. By default, graphs showing CPU, memory, network I/O and disk I/O are displayed on the tab. Click Actions to add more performance data and change the appearance of the graphs. For more information, see Configuring Performance Graphs.
Performance alerts can be generated when CPU, memory usage, network, storage throughput, or VM disk activity go over a specified threshold on a managed server, virtual machine, or storage repository. For more information, see Configuring Performance Alerts.
Select the top-level XenCenter item, a pool or a server in the Resources pane and then click on the Search tab to perform complex searches of your managed resources. You can construct queries based on object types, folders, and attributes such as name, description, tags, HA status or restart priority, and power state.
Create, delete and export VM snapshots, revert a VM to a selected snapshot, and use existing snapshots to create new VMs and templates on the Snapshots tab.
See VM Snapshots.
View the storage configuration of the selected virtual machine, server, resource pool, or storage repository on the Storage tab. The settings shown on this tab depend on the type of resource currently selected in the Resources pane.
|Selected resource||What’s shown on the Storage tab||Learn more|
|VMs and templates||Information about each virtual disk on the VM is shown, including its size and location (the SR where the virtual disk is located), its data access status and disk access priority. To edit a virtual disk’s settings, select it in the list and click Properties. Click Add to add a new disk or Attach to attach an existing disk.||Configuring Virtual Storage|
|Servers and pools||A list of the available storage repositories (SRs) is shown, with summary information about their type, size, free space, and share status. To edit the name or description of an SR, select it in the list and click Properties. Click Add to add a SR or Detach to detach the selected SR.||Managing Storage Repositories (SRs)|
