[CentOS-virt] Discover what vnet is attached to a kvm guest
Hi all, How can I see what vnet is attached to a certain kvm guest?? For example: I have a kvmguest1. When I launch this guest with virsh command, virsh creates a new vnetX interface for this guest. How can I extract this virtual net interface (vnet0, vnet1, vnet2 or so on) using a script?? Thanks. -- CL Martinez carlopmart {at} gmail {d0t} com

However, you could define this in the domain XML using the target tag within the interface container, e.g. using the libvirt example <interface type='network'> <source network='default'/> <target dev='vnet7'/> <mac address="00:11:22:33:44:55"/> </interface>>From there, I suppose you could extract the information from therelevant xml with your script.
