We can export the virtual machine we need through xencernter, we usually export the XVA format in the Xen platform, this selects a path and then completes the next step.
But sometimes we need to boast the platform to export virtual machines and then cross-platform to import the virtual machines we need, this time we need to export other formats of virtual machines such as OVF or OVA, this often we chose the Ovf\ova in Xencenter, and then choose a place to store the virtual machine, The next time, basically two minutes after the error will be prompted, "Export failed."
The solution is to give the exported virtual machine a static IP address of zero in Xencenter, which is used as the management address of the exported virtual machine to successfully export the required format of the virtual machine.
