You can export one or more VMs as an OVF or OVA package using the XenCenter Export wizard. To open the wizard, select the VM you want to export and on the VM menu, click Export. Note that the VMs must be shut down or suspended before they can be exported.
Note that you need an RBAC role of Pool Admin to export to OVF/OVA. The Export wizard will perform checks when it starts up to ensure that you have a Pool Admin role before allowing you to continue. See RBAC overview for more information about RBAC roles.
The export process may take some time, depending on the size of the virtual disks, the available network bandwidth, and the disk interface speed of the XenCenter host. Progress is displayed on the status bar at the bottom of the XenCenter window and on the Events view under Notifications.
To cancel an export in progress, click Notifications and then Events, find the export in the list of events, and click Cancel.
