Nothing that could happen during networkNotifyActualDevice() could justify unceremoniously killing the qemu process, but that's what we were doing. In particular, new code added in commit 85bcc022 (first appearred in libvirt-3.2.0) attempts to reattach tap devices to their assigned bridge devices when libvirtd restarts (to make it easier to recover from a restart of a libvirt network). But if the network has been stopped and *not* restarted, the bridge device won't exist and networkNotifyActualDevice() will fail. This patch changes networkNotifyActualDevice() and qemuProcessNotifyNets() to return void, so that qemuProcessReconnect() will soldier on regardless of what happens (any errors will still be logged though). Partially resolves: https://bugzilla.redhat.com/1442700 (cherry picked from commit cb182eb11d3a99adb06e188989899dcd488c43fc)
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.
