Until now there has been an extra bit of code in qemuDomainDeviceCalculatePCIConnectFlag() (one of the two callers of virPCIDeviceIsPCIExpress()) that tries to determine if a device is PCIe by looking at the *length* of its sysfs config file; it only does this when libvirt is running as a non-root process. This patch takes advantage of our newfound ability to tell the difference between "I read a 0 from the device PCI config file" and "I couldn't read the PCI Express Capabilities because I don't have sufficient permission" to put the file length check down in virPCIDeviceIsPCIExpress(), and do that check any time we fail while reading the config file (not only when the process is non-root).

Libvirt API for virtualization
Libvirt provides a portable, long term stable C API for managing the virtualization technologies provided by many operating systems. It includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER Hypervisor.
For some of these hypervisors, it provides a stateful management daemon which runs on the virtualization host allowing access to the API both by non-privileged local users and remote users.
Layered packages provide bindings of the libvirt C API into other languages including Python, Perl, PHP, Go, Java, OCaml, as well as mappings into object systems such as GObject, CIM and SNMP.
