[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [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?
