I recently installed the updates for Fedora 17, among which was an upgrade from Linux Kernel 3.7.x to 3.8.x. Now I can't build Libvirt! It is giving me this error:

checking linux/if_bridge.h usability... no
checking linux/if_bridge.h presence... yes
configure: WARNING: linux/if_bridge.h: present but cannot be compiled
configure: WARNING: linux/if_bridge.h:     check for missing prerequisite headers?
configure: WARNING: linux/if_bridge.h: see the Autoconf documentation
configure: WARNING: linux/if_bridge.h:     section "Present But Cannot Be Compiled"
configure: WARNING: linux/if_bridge.h: proceeding with the compiler's result
configure: WARNING:     ## ------------------------------------- ##
configure: WARNING:     ## Report this to libvir-list redhat com ##
configure: WARNING:     ## ------------------------------------- ##
checking for linux/if_bridge.h... no

How can I fix this so I can build Libvirt again?

Apparently the build failure was being caused by the header file /usr/include/linux/if_bridge.h. Fortunately the fix is quite easy (once you know what to do).

  1. Open /usr/include/linux/if_bridge.h in a text editor
  2. Add this include line, #include <netinet/ip6.h>
  3. Rebuild

You will have to reapply this fix each time you boot into a different kernel version since the /usr/include/linux/ header files are wiped out.
