Yes it works.
Thanks. You saved my life.
Let me ask something I can't see it in the code:
This is the code that i found:
static int
networkStartNetworkVirtual(virNetworkObjPtr network)
{
size_t i;
bool v4present = false, v6present = false;
virErrorPtr save_err = NULL;
virNetworkIpDefPtr ipdef;
virNetworkRouteDefPtr routedef;
char *macTapIfName = NULL;
int tapfd = -1;
/* Check to see if any network IP collides with an existing
route */
if (networkCheckRouteCollision(network->def) < 0)
return -1;
/* Create and configure the bridge device */
if (virNetDevBridgeCreate(network->def->bridge) < 0)
return -1;
....
It either create device or return -1. So I was hopeless about a
solution :)
But your method saved me.

Hello,
Simply I want to create a network on an existing bridge.
My XML:
<network>
<name>nn1</name>
<bridge name="br-nn1" />
</network>
I think what you want is this:
<network>
<name>nn1</name>
<forward mode='bridge'/>
<bridge name='br-nn1'/>
</network>
https://libvirt.org/formatnetwork.html#examplesBridge
(Originally a network with no <forward> element was
considered to be a virtual network with bridge created by libvirt
but no physical device attached. When support for networks that
used an existing bridge was added, we had to maintain backward
compatibility, so we decided that the new type of network would be
identified by setting <forward mode='bridge'/> on a network
that has a bridge name defined.)
when i want to start network I got "File exist" error.
error: Failed to start network nn1
error: Unable to create bridge br-nn1: File exist
I could define on older releases but now I can't.
Ubuntu 15.04 / libvirt version: 1.2.12
No, that wouldn't have worked in any older release of libvirt.
Perhaps you've forgotten that you previously had <forward
mode='bridge'/> in your definition?
virsh version:
Compiled against library: libvirt 1.2.12
Using library: libvirt 1.2.12
Using API: QEMU 1.2.12
Running hypervisor: QEMU 2.2.0
Is there any way to activate network?
Regards.
