Re: [Xen-devel] [PATCH] libxl: create pci backend only when there are pci devices

[Roger Pau Monnà <roger.pau@xxxxxxxxxxxxx>]

This was commited as a part of another patch, and I've decided to
submit it alone. This solves a problem with NetBSD Dom0 and at least
Linux DomU, the DomU kernel waited a very long time at XENBUS init,
because it was unable to attach the PCI devices (although there were
no PCI devices, only an empty pci entry in xenstore). This prevents
libxl from adding the pci entries to xenstore if there are no PCI
devices and solves the problem. I don't have any Linux boxes, but I
think this should not break anything.

If the patch is correct, please add it to xen-4.1 too.

Regards, Roger.
