[Bug 790837] [NEW] Fails to start inside PV domU

[Soren Hansen]

Public bug reported:

Xen PV domU's have no PCI bus. libvirt's
src/node_device/node_device_udev.c calls pci_system_init which looks for
/sys/bus/pci. If it does not find /sys/bus/pci (which it won't in a Xen
PV domU) it returns unsuccesfully, which libvirt considers fatal.

It's perfectly reasonable to want to run libvirt in a paravirt Xen domU,
e.g. for running LXC, QEmu or UML guests. Additionally, the PCI check is
disabled on s390, and a failing check is ignored for qemu:///session, so
I don't see how it can be absolutely required for qemu:///system on
non-s390.
