Partially reverts commit 5754dbd. The code in the specfile adds a MAC address to every <bridge>, even for <forward mode='bridge'> for which we don't support changing MAC addresses. Remove it completely. For new networks, we have been adding MAC addresses on definition/creation since the commit mentioned above. For existing networks (pre-0.9.0), the MAC is added by the previous commit. https://bugzilla.redhat.com/show_bug.cgi?id=1156367 --- libvirt.spec.in | 42 ------------------------------------------ src/conf/network_conf.c | 4 ++++ 2 files changed, 4 insertions(+), 42 deletions(-) diff --git a/libvirt.spec.in b/libvirt.spec.in index 6fcaa3e..43b3899 100644 --- a/libvirt.spec.in +++ b/libvirt.spec.in @@ -1606,48 +1606,6 @@ exit 0 %post daemon - %if %{with_network} -# All newly defined networks will have a mac address for the bridge -# auto-generated, but networks already existing at the time of upgrade -# will not.
