Libvirt native C API and daemons
a24b1d9eda
introduced into the qemudNetworkIfaceConnect() function. In particular, there
is a call:
if (VIR_ALLOC_N(vm->tapfds, vm->ntapfds+2) < 0)
goto no_memory;
However, the tapfds structure is used to track *all* of the tap fds, and is
called once for each network that is being attached to the domain. VIR_ALLOC_N
maps to calloc(). So the first network would work just fine, but if you had
more than one network, subsequent calls to this function would blow away the
stored fd's that were already there and fill them all in with zeros. This
causes multiple problems, from the qemu domains not starting properly to
improper cleanup on shutdown. The attached patch just changes the VIR_ALLOC_N()
to a VIR_REALLOC_N(), and everything is happy again.

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.
