Due to debug logs like this: virPCIGetDeviceAddressFromSysfsLink:2432 : Attempting to resolve device path from device link '/sys/class/net/eth1/device/virtfn6' logStrToLong_ui:2369 : Converted '0000:07:00.7' to unsigned int 0 logStrToLong_ui:2369 : Converted '07:00.7' to unsigned int 7 logStrToLong_ui:2369 : Converted '00.7' to unsigned int 0 logStrToLong_ui:2369 : Converted '7' to unsigned int 7 virPCIGetDeviceAddressFromSysfs:1947 : virPCIDeviceAddress 0000:07:00.7 virPCIGetVirtualFunctions:2554 : Found virtual function 7 printed *once for each SR-IOV Virtual Function* of a Physical Function each time libvirt retrieved the list of VFs (so if the system has 128 VFs, there would be 900 lines of log for each call), the debug logs on any system with a large number of VFs was dominated by "information" that was possibly useful for debugging when the code was being written, but is now useless for debugging of any problem on a running system, and only serves to obscure the real useful information. This overkill has no place in production code, so this patch removes it.
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
