[libvirt] [PATCH 12/33] Fix error reporting in port profile parsing/formatting APIs
Daniel P. Berrange

Thu Nov 3 17:30:08 UTC 2011
From: "Daniel P. Berrange" <berrange at redhat.com>
The virtual port profile parsing/formatting APIs do not
correctly handle unknown profile type strings/numbers.
They behave as a no-op, instead of raising an error
* src/util/network.c, src/util/network.h: Fix error
handling of port profile APIs
* src/conf/domain_conf.c, src/conf/network_conf.c: Update
for API changes
