util: more verbose error when failing to create macvtap device
Investigation of a problem with creating passthrough macvtap devices (https://bugzilla.redhat.com/show_bug.cgi?id=1185501) has shown that this slightly more verbose failure message is useful. In particular, the mac address can be used to determine the domain. You could also figure this out by looking at preceding messages in a debug log, but this gets it in a single place. (cherry picked from commit 72423df9920491f8f59455a4161a7c31d1e15c8a)
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.
