Hello,<br>
<br>
Simply I want to create a network on an existing bridge.<br>
My XML:<br>
<br>
<meta http-equiv="content-type" content="text/html; charset=utf-8">
<network><br>
<name>nn1</name><br>
<bridge name="br-nn1" /><br>
</network><br>

I think what you want is this:<br>
<br>
<network><br>
<name>nn1</name><br>
<forward mode='bridge'/><br>
<bridge name='br-nn1'/><br>
</network><br>
<br>

<br>
(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.)<br>

when i want to start network I got "File exist" error.<br>

error: Failed to start network nn1<br>
error: Unable to create bridge br-nn1: File exist<br>

I could define on older releases but now I can't.<br>

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?<br>

Is there any way to activate network?<br>
