[Xen-devel] [PATCH] xend: passthrough: revert some parts of changeset 20348: 9ead82c46efd

["Cui, Dexuan" <dexuan.cui@xxxxxxxxx>]

Changeset 20348 breaks the device assignment (at least) in the
non-stubdomain case, e.g.,
1) we can't assign more than 1 device to hvm guest statically: 'xm create'
complains "Error: Device 0 (pci) is already connected";
2) after we assign 1 device to hvm guest statically and we 'xm pci-detach'
the device from guest later, we can find 'xm pci-list' still shows the device
is assigned to the guest, and we can't 'xm pci-attach' the device to the guest
any longer.

The patch reverts some parts of changeset 20348 to fix the above issues.

Hope this doesn't offend the passthrough in the stub-domain case.
Stefano, please have a look.

Thanks,
-- Dexuan
