PCI Backend Configuration - Permissive Flag

If the user-space quirks approach doesn't meet your needs you may want to enable the permissive flag for that device. To do so, first get the PCI domain, bus, slot, and function information from dom0 via lspci. Then augment the user-space policy for permissive devices. The permissive policy can be found in:

/etc/xen/xend-pci-permissive.sxp

Currently, the only way to reset the permissive flag is to unbind the device from the PCI Backend driver.
