eb72bd63c1
There are three functions that deal with allocating and freeing devices from a networks netdev/pci device pool: network(Allocate|Notify|Release)ActualDevice(). These functions also maintain a counter of the number of domains currently using a network (regardless of whether or not that network uses a device pool). Each of these functions had multiple log messages (output using VIR_DEBUG) that were in slightly different formats and gave varying amounts of information. This patch creates a single function to log the pertinent information in a consistent manner for all three of these functions. Along with assuring that all the functions produce a consistent form of output (and making it simpler to change), it adds the MAC address of the domain interface involved in the operation, making it possible to verify which interface of which domain the operation is being done for (assuming that all MAC addresses are unique, of course). All of these messages are raised from DEBUG to INFO, since they don't happen that often (once per interface per domain/libvirtd start or domain stop), and can be very informative and helpful - eliminating the need to log debug level messages makes it much easier to sort these out.
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.
