Hello All,

I am having trouble simulating a network cable disconnect with KVM. I
would like to test active backup bonding for a switch IOS upgrade in a
production environment.

Basically I have the VM running on a bridged network which is also tied
into GNS3 simulating a small-scale version of the production

I have tried bringing down the vnetX interface and the actual virtual
network itself (virbrX) with no luck.

Has anyone had to do this before/maybe knows some tips?

If more info is required about my setup, I can give it.
