In commit 991270db99 I've used virDomainNetGetActualHostdev() to get
the actual hostdev from a network when removing the network from the
list to avoid leaving the hostdev in the list. I didn't notice that this
function doesn't check if the actual network is allocated and
dereferences it. This crashes the daemon when cleaning up a domain
object in early startup phases when the actual network definition isn't
allocated. When the actual definition isn't present, the hostdev that
might correspond to it won't be present anyways so it's safe to return
NULL.
Thanks to Cole Robinson for noticing this problem.
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.
