During virtual network startup, the iptables rule that allows tftp traffic is only added if network->def->tftproot is non-empty, but when the virtual network is destroyed, we had been unconditionally trying to delete the rule. This was harmless, except that it created a bogus error message. This patch conditionalizes the delete command in the same manner that the insert command is already conditionalized.
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.
