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
