[Background: I'd like to actually test How to take down a static network interface when not connected? ]
I'm setting up a QEMU-KVM virtual machine using libvirt (via
virt-manager). I put two NICs on it (both virtio). They are bridged to a physical NIC on the host.
I want to test what NetworkManager does when I "unplug" one. But there isn't button/checkbox for that in virt-manager, nor a quick Google search turn up anything.
How do I emulate unplugging the network cable?
