[Xen-devel] xc.test_assign_device() doesn''t work for devices assigned via the traditional PCI passthrough(without VT-d).
e.g., with xen parameter ''iommu=on,no-pv'', after we assign a device to pv guest1, we can still assign the device to hvm guest2 because when xend creates guest2, it''s wrongly told by xc.test_assign() the device is not assigned. To judge if a device has been assigned, xc.test_assign() is not enough; maybe we also have to scan xenstore?
