Hi all,

When I defined a network use the host bridge “virbr1” an error occurred :

“libvir:  error : Unable to create bridge virbr1: File exists”

But how can I define this network use the host bridge “virbr1” ?

<network>              

<name>def1</name>    

<bridge name='virbr1'/>

<forward mode='nat'>   

<interface dev='eth0'/>

</forward>             

</network>             

Thanks,

Kevin
