[Xen-devel] It's said 'when the guest has PCI passthrough devices in use, operations like migration/save/restore are not possible.' where are the corresponding codes in xen?

It's said 'when the guest has PCI passthrough devices in use, operations like migration/save/restore are not possible.' where are the corresponding codes in xen?

 

I'm wondering how xend/xenlight tells whether a guest has a pci passthu device in use or not. 

1. thank you in advance!
