[Xen-devel] [PATCH] qemu: pci_scan everytime we register a device

[Stefano Stabellini <stefano.stabellini@xxxxxxxxxxxxx>]

Hi all,
when using stubdoms the pci devices visible when issuing a pci_scan
change dynamically with the devices that are actually assigned to the
stubdom.  For this reason every time we want to assign a new device to
the guest we need to rescan the pci bus.
