[libvirt-users] simulate "network cable unplugged"
Hi All, Using the virt-manager/libvirtd/qemu-kvm stack (centos 6), is it possible to leave a NIC "installed" but cause it to simulate that the network cable is unplugged? Preferably this could be "hot" plugged/unplugged but otherwise doing it cold. Guest os is also centos 6, in case it matters (shouldn't). Any pointers? Thanks, David Mansfield Cobite, INC.

Libvirt 0.9.5 added the ability to do <link state='down'/> for various networks; I'm not sure if this has been backported to your version of CentOS, or if you'll have to upgrade to something newer.
